CVE-2013-2573

TITLE

plural  TP-Link IP Camera  In products  OS  Command injection vulnerability

DESCRIPTION

A Command Injection vulnerability exists in the ap parameter to the /cgi-bin/mft/wireless_mft.cgi file in TP-Link IP Cameras TL-SC 3130, TL-SC 3130G, 3171G. and 4171G 1.6.18P12s, which could let a malicious user execute arbitrary code. plural TP-Link IP Camera Products include OS A command injection vulnerability exists.Information is acquired, information is falsified, and denial of service (DoS) May be in a state. TP-LINK IP Cameras are network camera products. A remote attacker can bypass the authentication by using a hard-coded username and password for the affected product (see CVE-2013-2572), and then use this command to inject the vulnerability to execute arbitrary commands from the administrator's web interface. *Advisory Information* Title: TP-Link IP Cameras Multiple Vulnerabilities Advisory ID: CORE-2013-0318 Advisory URL: http://www.coresecurity.com/advisories/tp-link-IP-cameras-multiple-vulnerabilities Date published: 2013-05-28 Date of last update: 2013-05-28 Vendors contacted: TP-Link Release mode: Coordinated release 2. *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 remote attacker: 1. [CVE-2013-2572] to bypass user web interface authentication using hard-coded credentials. 2. This flaw can also be used to obtain all credentials of registered users. 4. *Vulnerable Packages* . Tests and PoC were run on: . TL-SC 3130 [CVE-2013-2572] works with this device only . TL-SC 3130G . TL-SC 3171G . 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. http://www.tp-link.com/resources/software/TL-SC3430_V1_130527.zip . http://www.tp-link.com/resources/software/TL-SC3430N_V1_130527.zip . http://www.tp-link.com/resources/software/TL-SC3130_V1_130527.zip . http://www.tp-link.com/resources/software/TL-SC3130G_V1_130527.zip . http://www.tp-link.com/resources/software/TL-SC3171_V1_130527.zip . http://www.tp-link.com/resources/software/TL-SC3171G_V1_130527.zip . http://www.tp-link.com/resources/software/TL-SC4171G_V1_130527.zip 6. *Credits* 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 [1], 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/': 1. 'manufacture.cgi' 2. 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: /----- 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 -----/ 8. *Report Timeline* . 2013-04-29: Core Security Technologies notifies the TP-Link Customer Support of the vulnerabilities. Publication date is set for May 28th, 2013. 2013-04-30: TP-Link team asks for a report with technical information. 2013-05-02: Technical details sent to TP-Link. 2013-05-12: Vendor notifies that a new firmware will be released around May 20th. 2013-05-16: Core asks vendor if they are ready for coordinated public disclosure on May 20th. 2013-05-17: Vendor notifies that they have fixed the firmware but the testing process won't be ready before May 24th. 2013-05-20: Core notifies that the advisory publication was re-scheduled for Monday 27th. 2013-05-23: Vendor sends a copy of the beta firmware in order to confirm if issues were fixed. 2013-05-27: Vendor notifies that consumers are able to download the Beta firmware from TP-Link website. The final release will be made public in the following days, and will increase some new functions. 2013-05-28: Advisory CORE-2013-0318 published. 9. *References* [1] http://www.boa.org/. 10. *About CoreLabs* CoreLabs, the research center of Core Security Technologies, is charged with anticipating the future needs and requirements for information security technologies.
