A vulnerability, which was classified as critical, was found in PHP (Programming Language Software). This affects some unknown functionality of the file rfc1867.c of the component File Upload. The manipulation of the argument _FILES with an unknown input leads to a input validation vulnerability. CWE is classifying the issue as CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. This is going to have an impact on integrity, and availability. The summary by CVE is:

The file-upload implementation in rfc1867.c in PHP before 5.4.0 does not properly handle invalid [ (open square bracket) characters in name values, which makes it easier for remote attackers to cause a denial of service (malformed $_FILES indexes) or conduct directory traversal attacks during multi-file uploads by leveraging a script that lacks its own filename restrictions.

The weakness was published 05/23/2012 (Website). The advisory is shared at svn.php.net. This vulnerability is uniquely identified as CVE-2012-1172 since 02/14/2012. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details are known, but no exploit is available.

The vulnerability scanner Nessus provides a plugin with the ID 74607 (openSUSE Security Update : php5 (openSUSE-SU-2012:0551-1)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family SuSE Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 185005 (HP-UX Apache Web Server Running PHP Denial of Service Vulenrability (HPSBUX02791)).

Upgrading to version 5.1.0 eliminates this vulnerability.

The vulnerability is also documented in the databases at X-Force (75426) and Tenable (74607). Similar entries are available at 4600, 5319, 9012 and 60729.
