Reported to Mozilla: 2016-12-06
Mozilla made public: 2016-12-15
Declined bounty: 2017-01-30
Advisory released: 2017-05-16
Technical Details:
==============
A stack overflow DoS vulnerability affecting Firefox versions 50 through 55 was discovered by Geeknik Labs. This flaw does NOT affect ESR 45 or the latest version of the Tor Browser Bundle. This flaw can be triggered by simply visiting a website with the PoC code embedded in it and requires no further user interaction nor does it require any special privileges. Successful exploitation results in the browser tab crashing.

'Name' => 'WordPress PHPMailer Host Header Command Injection',
'Description' => %q{
This module exploits a command injection vulnerability in WordPress
version 4.6 with Exim as an MTA via a spoofed Host header to PHPMailer,
a mail-sending library that is bundled with WordPress.
A valid WordPress username is required to exploit the vulnerability.
Additionally, due to the altered Host header, exploitation is limited to
the default virtual host, assuming the header isn't mangled in transit.
If the target is running Apache 2.2.32 or 2.4.24 and later, the server
may have HttpProtocolOptions set to Strict, preventing a Host header
containing parens from passing through, making exploitation unlikely.

Windows: Running Object Table Register ROTFLAGS_ALLOWANYCLIENT EoP
Platform: Windows 10 10586/14393 not tested 8.1 Update 2 or Windows 7
Class: Elevation of Privilege
Summary:
By setting an appropriate AppID its possible for a normal user process to set a global ROT entry. This can be abused to elevate privileges.
Description:
NOTE: Im not sure which part of this chain to really report. As far as I can tell its pretty much all by design and fixing the initial vector seems difficult. Perhaps this is only a bug which can be fixed to prevent sandbox escapes?
When registering an object in the ROT the default is to only expose that registration to the same user identity on the same desktop/window station. This includes preventing the same user at different ILs (such as between sandbox and normal user) from seeing the same registration. However it could be imagined that you might want to register an entry for all users/contexts so IRunningObjectTable::Register takes a grfFlags parameter with the value ROTFLAGS_ALLOWANYCLIENT which allows the ROT entry to be exposed to all users.
The description of this flag indicates it can only be used if the COM process is a Local Service or a RunAs application. In fact theres an explicit ROTFlags value for the AppID which would grant the privilege to a normal application. Quick testing proves this to be correct, a “normal” application cannot expose the ROT entry to any client as RPCSS does a check that the calling process is allowed to expose the entry. However there are two clear problems with the check. Creating a RunAs COM object in the current session would typically run at the same privilege level as the caller, therefore an application which wanted to abuse this feature could inject code into that process. Secondly while its not possible to register a per-user COM object which specifies a RunAs AppID its possible to explicitly set the AppID when calling CoInitializeSecurity (either via the GUID or by naming your program to match one which maps to the correct AppID).
Therefore in the current implementation effectively any process, including sandboxed ones should be able to register a global ROT entry. What can we do with this? The ROT is mainly used for OLE duties, for example Word and Visual Studio register entries for each document/project open. It would be nice not to rely on this, so instead Ill abuse another OLE component, which weve seen before, the fact that LoadTypeLib will fall back to a moniker if it cant find the type library file specified.
If the file loading fails then LoadTypeLib will effectively call MkParseDisplayName on the passed in string. One of the things MPDN does is try and create a file moniker with the string passed in as an argument. File Monikers have an interesting feature, the COM libraries will check if theres a registered ROT entry for this file moniker already present, if it is instead of creating a new object it will call IRunningObjectTable::GetObject instead when binding. So as we can register a ROT entry for any user in any context we can provide our own implementation of ITypeLib running inside our process, by registering it against the path to the type library any other process which tries to open that library would instead get our spoofed one, assuming we can force the file open to fail.
This is the next key part, looking at the LoadTypeLib implementation the code calls FindTypeLib if this function fails the code will fall back to the moniker route. Theres two opportunities here, firstly CreateFile is called on the path, we could cause this to fail by opening the file with no sharing mode, in theory it should fail. However in practice it doesnt most type libraries are in system location, if you dont have the possibility of write permission on the file the OS automatically applies FILE_SHARE_READ which makes it impossible to lock the file in its entirety. Also some TLBs are stored inside a DLL which is then used so this route is out. Instead the other route is more promising, VerifyIsExeOrTlb is called once the file is open to check the type of file to parse. This function tries to load the first 64 bytes and checks for magic signatures. We can cause the read to fail by using the LockFile API to put an exclusive lock on that part of the file. This also has the advantage that it doesnt affect file mappings so will also work with loaded DLLs.
We now can cause any user of a type library to get redirected to our “fake” one without abusing impersonation/symbolic link tricks. How can we use this to our advantage? The final trick is to abuse again the auto-generation of Stubs/Proxies from automation compatible interfaces. If we can get a more privileged process to use our type library when creating a COM stub we can cause a number of memory safety issues such as type confusion, arbitrary memory read/writes and extending the vtable to call arbitrary functions. This is an extremely powerful primitive, as long as you can find a more privileged process which uses a dual automation interface. For example the FlashBroker which is installed on every Win8+ machine is intentionally allowed to be created by sandboxed IE/Edge and uses dual interfaces with auto-generated Stubs. We could abuse for example the BrokerPrefSetExceptionDialogSize and BrokerPrefGetExceptionDialogSize to do arbitrary memory writes. This all works because the stub creation has no was of ensuring that the actual server implementation matches the generated stub (at least without full symbols) so it will blindly marshal pointers or call outside of the object's vtable.
Proof of Concept:
Ive provided a PoC as a C# project. You need to compile it first. It fakes out the Windows Search Services type library to modify the IGatherManagerAdmin2::GetBackoffReason method so that instead of marshaling a pointer to an integer for returning the caller can specify an arbitrary pointer value. When the method on the server side completes it will try and write a value to this address which will cause a Write AV. The Windows Search service would be ideal for abuse but many of the functions seem to require Administrator access to call. Thats not to say you couldnt convert this into a full working exploit but I didnt.
1) Compile the C# project. It should be compiled as a 64 bit executable.
2) Restart the Windows Search service just to ensure it hasnt cached the stub previously. This probably isnt necessary but just to be certain.
3) Attach a debugger to SearchIndexer.exe to catch the crash.
4) Execute the PoC as a normal user (do not run under the VSHOST as the CoInitializeSecurity call will fail). You need to pass the path to the provided mssitlb.tlb file which has been modified appropriately.
5) The service should crash trying to write a value to address 0x12345678

Windows: COM Aggregate Marshaler/IRemUnknown2 Type Confusion EoP
Platform: Windows 10 10586/14393 not tested 8.1 Update 2
Class: Elevation of Privilege
Summary:
When accessing an OOP COM object using IRemUnknown2 the local unmarshaled proxy can be for a different interface to that requested by QueryInterface resulting in a type confusion which can result in EoP.
Description:
Querying for an IID on a OOP (or remote) COM object calls the ORPC method RemQueryInterface or RemQueryInterface2 on the default proxy. This request is passed to the remote object which queries the implementation object and if successful returns a marshaled representation of that interface to the caller.
The difference between RemQueryInterface and RemQueryInterface2 (RQI2) is how the objects are passed back to the caller. For RemQueryInterface the interface is passed back as a STDOBJREF which only contains the basic OXID/OID/IPID information to connect back. RemQueryInterface2 on the other hand passes back MInterfacePointer structures which is an entire OBJREF. The rationale, as far as I can tell, is that RQI2 is used for implementing in-process handlers, some interfaces can be marshaled using the standard marshaler and others can be custom marshaled. This is exposed through the Aggregate Standard Marshaler.
The bug lies in the implementation of unpacking the results of the the RQI2 request in CStdMarshal::Finish_RemQIAndUnmarshal2. For each MInterfacePointer CStdMarshal::UnmarshalInterface is called passing the IID of the expected interface and the binary data wrapped in an IStream. CStdMarshal::UnmarshalInterface blindly unmarshals the interface, which creates a local proxy object but the proxy is created for the IID in the OBJREF stream and NOT the IID requested in RQI2. No further verification occurs at this point and the created proxy is passed back up the call stack until the received by the caller (through a void** obviously).
If the IID in the OBJREF doesnt match the IID requested the caller doesnt know, if it calls any methods on the expected interface it will be calling a type confused object. This could result in crashes in the caller when it tries to access methods on the expected interface which arent there or are implemented differently. You could probably also return a standard OBJREF to a object local to the caller, this will result in returning the local object itself which might have more scope for exploiting the type confusion. In order to get the caller to use RQI2 we just need to pass it back an object which is custom marshaled with the Aggregate Standard Marshaler. This will set a flag on the marshaler which indicates to always use the aggregate marshaler which results in using RQI2 instead of RQI. As this class is a core component of COM its trusted and so isnt affected by the EOAC_NO_CUSTOM_MARSHAL setting.
In order to exploit this a different caller needs to call QueryInterface on an object under a less trusted user's control. This could be a more privileged user (such as a sandbox broker), or a privileged service. This is pretty easy pattern to find, any method in an exposed interface on a more trusted COM object which takes an interface pointer or variant would potentially be vulnerable. For example IPersistStream takes an IStream interface pointer and will call methods on it. Another type of method is one of the various notification interfaces such as IBackgroundCopyCallback for BITS. This can probably also be used remotely if the attacker has the opportunity to inject an OBJREF stream into a connection which is set to CONNECT level security (which seems to be the default activation security).
On to exploitation, as you well know Ive little interest in exploiting memory corruptions, especially as this would either this will trigger CFG on modern systems or would require a very precise lineup of expected method and actual called method which could be tricky to exploit reliably. However I think at least using this to escape a sandbox it might be your only option. So Im not going to do that, instead Im going to exploit it logically, the only problem is this is probably unexploitable from a sandbox (maybe) and requires a very specific type of callback into our object.
The thing Im going to exploit is in the handling of OLE Automation auto-proxy creation from type libraries. When you implement an Automation compatible object you could implement an explicit proxy but if youve already got a Type library built from your IDL then OLEAUT32 provides an alternative. If you register your interface with a Proxy CLSID for PSOAInterface or PSDispatch then instead of loading your PS DLL it will load OLEAUT32. The proxy loader code will lookup the interface entry for the passed IID to see if theres a registered type library associated with it. If there is the code will call LoadTypeLib on that library and look up the interface entry in the type library. It will then construct a custom proxy object based on the type library information.
The trick here is while in general we dont control the location of the type library (so its probably in a location we can write to such as system32) if we can get an object unmarshaled which indicates its IID is one of these auto-proxy interfaces while the privileged service is impersonating us we can redirect the C: drive to anywhere we like and so get the service to load an arbitrary type library file instead of a the system one. One easy place where this exact scenario occurs is in the aforementioned BITS SetNotifyInterface function. The service first impersonates the caller before calling QI on the notify interface. We can then return an OBJREF for a automation IID even though the service asked for a BITS callback interface.
So what? Well its been known for almost 10 years that the Type library file format is completely unsafe. It was reported and it wasnt changed, Tombkeeper highlighted this in his Sexrets [sic] of LoadLibrary presentation at CSW 2015. You can craft a TLB which will directly control EIP. Now youd assume therefore Im trading a unreliable way of getting EIP control for one which is much easier, if you assume that youd be wrong. Instead Im going to abuse the fact that TLBs can have referenced type libraries, which is used instead of embedding the type definitions inside the TLB itself. When a reference type is loaded the loader will try and look up the TLB by its GUID, if that fails it will take the filename string and pass it verbatim to LoadTypeLib. Its a lesser know fact that this function, if it fails to find a file with the correct name will try and parse the name as a moniker. Therefore we can insert a scriptlet moniker into the type library, when the auto-proxy generator tries to find how many functions the interface implements it walks the inheritance chain, which causes the referenced TLB to be loaded, which causes a scriptlet moniker to be loaded and bound which results in arbitrary execution in a scripting language inside the privileged COM caller.
The need to replace the C: drive is why this wont work as a sandbox escape. Also it's a more general technique, not specific to this vulnerability as such, you could exploit it in the low-level NDR marshaler layer, however its rare to find something impersonating the caller during the low-level unmarshal. Type libraries are not loaded using the flag added after CVE-2015-1644 which prevent DLLs being loaded from the impersonate device map. I think you might want to fix this as well as theres other places and scenarios this can occur, for example theres a number of WMI services (such as anything which touches GPOs) which result in the ActiveDS com object being created, this is automation compatible and so will load a type library while impersonating the caller. Perhaps the auto-proxy generated should temporarily disable impersonation when loading the type library to prevent this happening.
Proof of Concept:
Ive provided a PoC as a C++ source code file. You need to compile it first. It abuses the BITS SetNotifyInterface to get a type library loaded under impersonation. We cause it to load a type library which references a scriptlet moniker which gets us code execution inside the BITS service.
1) Compile the C++ source code file.
2) Execute the PoC from a directory writable by the current user.
3) An admin command running as local system should appear on the current desktop.
Expected Result:
The caller should realize theres an IID mismatch and refuse to unmarshal, or at least QI the local proxy for the correct interface.
Observed Result:
The wrong proxy is created to that requested resulting in type confusion and an automation proxy being created resulting in code execution in the BITS server.

This module exploits an unauthenticated remote command execution vulnerability
in the console component of Serviio Media Server versions 1.4 to 1.8 on
Windows operating systems.
The console service (on port 23423 by default) exposes a REST API which
which does not require authentication.
The 'action' API endpoint does not sufficiently sanitize user-supplied data
in the 'VIDEO' parameter of the 'checkStreamUrl' method. This parameter is
used in a call to cmd.exe resulting in execution of arbitrary commands.
This module has been tested successfully on Serviio Media Server versions

SQL injection in INFOR EAM V11.0 Build 201410 search fields (web/base/..) via filtervalue parameter
-------------------
Assigned CVE: CVE-2017-7952
Reproduction steps:
-------------------
1. Log in with your EAM account
2. Go to any page with a search or filter field in it (for example web/base/WSJOBS.xmlhttp)
3. Make any search and intercept the request with a proxy
4. In the intercepted request, replace the value of "filteroperator" parameter with IN.
5. The "filtervalue" become vulnerable to SQL Injection
Example:
-------------------
URL:http://<EAM_IP>/web/base/WSJOBS.xmlhttp
POST DATA:
GRID_ID=<ID>&GRID_NAME=WSJOBS&DATASPY_ID=<ID>&USER_FUNCTION_NAME=WSJOBS&SYSTEM_FUNCTION_NAME=WSJOBS&CURRENT_TAB_NAME=LST&COMPONENT_INFO_TYPE=DATA_ONLY&filterfields=<field>&filteroperator=IN&filtervalue=<injection point>
Exploitability
-------------------
Since the SQL injection vulnerability is available for any logged users, an
attacker needs a valid credential to exploit that vulnerability. By
exploiting that SQL Injection the attacker could obtain any available data
(even if they dont belongs directly to him), eventually deleting and
replacing data as well.
Impact
-------------------
This vulnerability allows full database access. It includes sensitive
information that normally should be accessed by specific users.
An attacker could dump the user table, which contains usernames and
password hashes, and proceed to bruteforcing passwords offline and could
possibly obtain administrative credentials, or could access private files
or personal details such as: telephone numbers, physical address and
private assets.
Obtaining administrative credentials would allow an attacker to perform
actions like: add or deleting users, jobs, and everything else an admin can
do.
By having access to sensible information the attacker could eventually
pivoting them to perform further attacks on different target assets.

Stored XSS in INFOR EAM V11.0 Build 201410 via comment fields
-------------------
Assigned CVE: CVE-2017-7953
Reproduction steps:
-------------------
1. Log in with your EAM account
2. Go to the jobs page
3. Click on a record and open its page
4. Go to "Comments" tab
4. Click the add new comment button
5. Insert a comment containing javascript code, e.g. <img src=fakesource onerror="alert(document.cookie)"> Fake comment here
6. Save, and after page reloading the XSS should trigger
Example:
-------------------
PoC Screenshot: https://www.dropbox.com/s/2b859x9go8v9f2l/xss.png?dl=0
Exploitability
-------------------
In EAM software user comments have read classification to every
authenticated users. Any authenticated user could became a valid victim to
the described attack by navigate (spontaneously or not) to the infected
page. The comment visualization triggers injected javascript code.
On the other side any user able to write a comment could become a possible
attacker by introducing javascript into the comment body.
Impact
-------------------
By reading browser cookies an attacker could ultimately grab administrative
credentials having access to each available EAM action.
The vulnerability could ultimately allow an attacker to steal credential,
leak sensitive data, trick user to download malware.
