PHP 5.2.3 fnmatch pattern code injection

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.

A vulnerability was found in PHP 5.2.3 (Programming Language Software). It has been rated as problematic. This issue affects the function fnmatch. The manipulation of the argument pattern with an unknown input leads to a code injection vulnerability. Using CWE to declare the problem leads to CWE-94. The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. Impacted is availability. The summary by CVE is:

PHP before 5.2.3 allows context-dependent attackers to cause a denial of service (application crash) via (1) a long string in the pattern parameter to the glob function; or (2) a long string in the string parameter to the fnmatch function, accompanied by a pattern parameter value with undefined characteristics, as demonstrated by a "*[1]e" value. NOTE: this might not be a vulnerability in most web server environments that support multiple threads, unless these issues can be demonstrated for code execution.

The bug was discovered 09/04/2007. The weakness was shared 09/04/2007 by Rasmus Lerdorf with SecurityReason (Website). It is possible to read the advisory at redhat.com. The identification of this vulnerability is CVE-2007-4782 since 09/10/2007. The exploitation is known to be easy. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Technical details as well as a public exploit are known. The attack technique deployed by this issue is T1059 according to MITRE ATT&CK.

The exploit is available at securityfocus.com. It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 67711 (Oracle Linux 3 / 5 : php (ELSA-2008-0544)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Oracle Linux Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 165666 (SUSE Enterprise Linux Security Update php4, php5 (SUSE-SA:2008:004)).

Upgrading to version 5.2.3 eliminates this vulnerability. A possible mitigation has been published 12 months after the disclosure of the vulnerability.
