Detailsinfo

A vulnerability, which was classified as critical, was found in PHP 5.2.0 (Programming Language Software). Affected is an unknown function. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Buffer underflow in the PHP_FILTER_TRIM_DEFAULT macro in the filtering extension (ext/filter) in PHP 5.2.0 allows context-dependent attackers to execute arbitrary code by calling filter_var with certain modes such as FILTER_VALIDATE_INT, which causes filter to write a null byte in whitespace that precedes the buffer.

The bug was discovered 03/12/2007. The weakness was released 03/14/2007 by Stefan Esser (Website). The advisory is shared for download at debian.org. This vulnerability is traded as CVE-2007-1453 since 03/14/2007. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Technical details are unknown but a public exploit is available.

The exploit is shared for download at securityfocus.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 2 days. During that time the estimated underground price was around $25k-$100k. The vulnerability scanner Nessus provides a plugin with the ID 25100 (Debian DSA-1283-1 : php5 - several vulnerabilities), which helps to determine the existence of the flaw in a target environment.
