|
||||
https://github.com/fjserna/CVE-2015-7547
|
||||
|
||||
Technical information:
|
||||
|
||||
glibc reserves 2048 bytes in the stack through alloca() for the DNS answer at _nss_dns_gethostbyname4_r() for hosting responses to a DNS query.
|
||||
|
||||
Later on, at send_dg() and send_vc(), if the response is larger than 2048 bytes, a new buffer is allocated from the heap and all the information (buffer pointer, new buffer size and response size) is updated.
|
||||
|
||||
Under certain conditions a mismatch between the stack buffer and the new heap allocation will happen. The final effect is that the stack buffer will be used to store the DNS response, even though the response is larger than the stack buffer and a heap buffer was allocated. This behavior leads to the stack buffer overflow.
|
||||
|
||||
The vectors to trigger this buffer overflow are very common and can include ssh, sudo, and curl. We are confident that the exploitation vectors are diverse and widespread; we have not attempted to enumerate these vectors further.
|
||||
|
||||
We are providing this code as-is. You are responsible for protecting yourself,
|
||||
your property and data, and others from any risks caused by this code. This
|
||||
code may cause unexpected and undesirable behavior to occur on your machine.
|
||||
This code may not detect the vulnerability on your system.
|
||||
|
||||
Note that this POC consists of two components: server code and client code.
|
||||
The server code triggers the vulnerability and therefore will crash the client
|
||||
code. Note also that it is necessary to set the nameserver to point to the
|
||||
server code, and doing so could cause other programs that call into the
|
||||
getaddrinfo() function to crash while testing is underway. This POC code is
|
||||
provided "as is" with no warranties, whether express or implied, including
|
||||
without limitation any warranties or merchantability, fitness for a particular
|
||||
use and noninfringement. Google assumes no responsibility for your proper
|
||||
installation and use of the POC code.

About Vulnerability
|
||||
-------------------
|
||||
This Application is vulnerable to a combination of CSRF/XSS attack meaning that if an admin user can be tricked to visit a crafted URL created by attacker (via spear phishing/social engineering), the attacker can insert arbitrary script into admin page. Once exploited, admin?s browser can be made t do almost anything the admin user could typically do by hijacking admin's cookies etc.
|
||||
|
||||
Vulnerability Class
|
||||
===================
|
||||
Cross Site Request Forgery (https://www.owasp.org/index.php/Cross-Site_Request_Forgery_%28CSRF%29)

||||
Cross Site Scripting (https://www.owasp.org/index.php/Top_10_2013-A3-Cross-Site_Scripting_(XSS)
|
||||
|
||||
Steps to Reproduce: (POC)
|
||||
=========================
|
||||
|
||||
* Add follwing code to webserver and send that malicious link to application Admin.
|
||||
* The admin should be loggedin when he clicks on the link.
|
||||
* Soical enginering might help here

===========================
|

phpMyBackupPro v.2.5 (PMBP)
|
||||
|
||||
phpMyBackup Pro is a very easy to use, free, web-based MySQL backup
|
||||
application, licensed under the GNU GPL.
|
||||
You can create scheduled backups, manage and restore them, download or
|
||||
email them and a lot more.
|

|
||||
Vulnerability Type:
|
||||
=========================
|
||||
Remote Command Execution / CSRF
|
||||
|
||||
|
||||
CVE Reference:
|
||||
==============
|
||||
N/A
|
||||
|
||||
|
||||
Vulnerability Details:
|
||||
=====================
|
||||
|
||||
phpMyBackupPro uses PHP configuration files (global_conf.php) to manage
|
||||
settings, allowing user to change things like sql host, language, email
|
||||
etc..
|
||||
However, a malicious local user can also inject persistent arbitrary PHP/OS
|
||||
commands into the configuration to be executed on the host system.
|
||||
The remote command execution can also be a result of a CSRF driveby by if
|
||||
currently logged admin visits an attackers webpage.
|
||||
|
||||
Attackers can inject and write to disk arbitrary PHP code into the
|
||||
global_conf.php configuration file if a victim visits a malicious webpage
|
||||
or clicks an
|
||||
infected link via a CSRF vector or additionally from a local malicious user
|
||||
in shared host type environment.
|
||||
|
||||
first we escape the single quotes etc... so we can close the expected
|
||||
entry, then we leverage the backtick "`" operator to have PHP execute OS
|
||||
commands
|
||||
on victims system as it works just as well without having to deal with all
|
||||
the quote escaping.
|
||||
|
||||
e.g. payload that handles the single "'" quote an forward slashes "/"...
|
||||
|
||||
''///\\');exec(`c:/\Windows/\system32/\calc.exe`); ///\';
|
||||
|
||||
|
||||
The above when injected will result in a write to $CONF variables in
|
||||
global_conf.php as follows...
|
||||
|
||||
$CONF['lang']=ue('\'\'///\\');exec(`c:/Windows/system32/calc.exe`);
|
||||
///\';');
|
||||
|
||||
OR...
|
||||
|
||||
$CONF['email']=ue('\'\'///\\');exec(`c:/Windows/system32/calc.exe`);
|
||||
///\';');
|
||||
|
||||
|
||||
Exploit code(s):
|
||||
===============
|
||||
|
||||
Send admin infected link or convince them to visit our malicious webpage,
|
||||
then if the user is logged in and...
|
||||
a) clicks our link or visits our evil webpage or
|
||||
b) submits the form locally (malicious user) then BOOOOOOOOOOOM!
