SECUNIA ADVISORY ID: SA31295

VERIFY ADVISORY: http://secunia.com/advisories/31295/

CRITICAL: Moderately critical

IMPACT: Exposure of system information, Exposure of sensitive information

SOFTWARE: Coppermine Photo Gallery 1.x - http://secunia.com/product/1427/

DESCRIPTION: EgiX has discovered a vulnerability in Coppermine Photo Gallery, which can be exploited by malicious people to disclose sensitive information.

Input passed in the "lang" part encoded in the "data" cookie is not properly verified before being used to include files. This can be exploited to include arbitrary files from local resources via directory traversal attacks and NULL bytes. Successful exploitation requires that "Character encoding" is set to "Unicode (recommended) (utf-8)", which is the default value. The vulnerability is confirmed in version 1.4.18. Other versions may also be affected.

SOLUTION: Edit the source code to ensure that input is properly verified. Set "Character encoding" to another value than "Unicode".

PROVIDED AND/OR DISCOVERED BY: EgiX
