PHP up to 5.1.2 Session Identifier Stored memory corruption

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability was found in PHP (Programming Language Software). It has been classified as critical. This affects an unknown code of the component Session Identifier. The manipulation with an unknown input leads to a memory corruption vulnerability (Stored). 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. The summary by CVE is:

PHP before 4.4.3 and 5.x before 5.1.4 does not limit the character set of the session identifier (PHPSESSID) for third party session handlers, which might make it easier for remote attackers to exploit other vulnerabilities by inserting PHP code into the PHPSESSID, which is stored in the session file. NOTE: it could be argued that this not a vulnerability in PHP itself, rather a design limitation that enables certain attacks against session handlers that do not account for this limitation.

The bug was discovered 08/21/2006. The weakness was released 08/24/2006 by Stefan Esser as not defined posting (Bugtraq). The advisory is shared at securityfocus.com. This vulnerability is uniquely identified as CVE-2006-4433 since 08/28/2006. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Neither technical details nor an exploit are publicly available.

It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 22268 (PHP < 4.4.3 / 5.1.4 Multiple Vulnerabilities), which helps to determine the existence of the flaw in a target environment. It is assigned to the family CGI abuses and running in the context r.

Upgrading to version 4.4.3 eliminates this vulnerability. A possible mitigation has been published before and not just after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at Tenable (22268), SecurityFocus (BID 17296†), OSVDB (28233†), Secunia (SA21573†) and Vulnerability Center (SBV-18837†). Entries connected to this vulnerability are available at VDB-2115, VDB-2493, VDB-2492 and VDB-32000. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
