TP-Link IP Cameras Multiple Vulnerabilities
1. *Advisory Information*
Title: TP-Link IP Cameras Multiple Vulnerabilities
Advisory ID: CORE-2013-0318
Date published: 2013-05-28
Date of last update: 2013-05-28
Vendors contacted: TP-Link
Release mode: Coordinated release
2. *Vulnerability Information*
Class: Use of hard-coded credentials [CWE-798], OS command injection [CWE-78]
Impact: Code execution, Security bypass
Remotely Exploitable: Yes
Locally Exploitable: No
CVE Name: CVE-2013-2572, CVE-2013-2573
3. *Vulnerability Description*
Multiple vulnerabilities have been found in TP-Link IP cameras based on
firmware v1.6.18P12 and below, that could allow an unauthenticated
1. [CVE-2013-2572] to bypass user web interface authentication using
2. [CVE-2013-2573] to execute arbitrary commands from the
administration web interface. This flaw can also be used to obtain all
credentials of registered users.
4. *Vulnerable Packages*
. TP-Link IP cameras based on firmware v1.6.18P12 and below.
Tests and PoC were run on:
. TL-SC 3130 [CVE-2013-2572] works with this device only
. TL-SC 3130G
. TL-SC 3171G
. TL-SC 4171G
Other TP-Link cameras and firmware versions are probably affected too,
but they were not checked.
5. *Vendor Information, Solutions and Workarounds*
Vendor provides the links to patched firmware versions. This software is
*beta*, TP-Link will release the final versions with release notes and
some new functions and fixes in the following days.
These vulnerabilities were discovered and researched by Nahuel Riva and
Francisco Falcon from Core Exploit Writers Team. The publication of this
advisory was coordinated by Fernando Miranda from Core Advisories Team.
7. *Technical Description / Proof of Concept Code*
7.1. *Hard-Coded Credentials in Administrative Web Interface*
[CVE-2013-2572] TP-Link IP cameras use the Boa web server , a popular
tiny server for embedded Linux devices. 'boa.conf' is the Boa
configuration file, and the following account can be found inside:
# MFT: Specify manufacture commands user name and password
MFT manufacture erutcafunam
This account is not visible from the user web interface; users are not
aware of the existence and cannot eliminate it. Through this account it
is possible to access two CGI files located in '/cgi-bin/mft/':
The last file contains the OS command injection showed in the following
7.2. *OS Command Injection in wireless_mft.cgi*
[CVE-2013-2573] The file '/cgi-bin/mft/wireless_mft.cgi', has an OS
command injection in the parameter 'ap' that can be exploited using the
hard-coded credentials showed in the previous section:
The following proof of concept copies the file where the user
credentials are stored in the web server root directory:
Afterwards, the user credentials can be obtained by requesting:
