A vulnerability classified as critical has been found in PHP 5.3.7/5.3.8 (Programming Language Software). Affected is the function __autoload. The manipulation with an unknown input leads to a code injection vulnerability. CWE is classifying the issue as 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. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

The is_a function in PHP 5.3.7 and 5.3.8 triggers a call to the __autoload function, which makes it easier for remote attackers to execute arbitrary code by providing a crafted URL and leveraging potentially unsafe behavior in certain PEAR packages and custom autoloaders.

The weakness was shared 11/03/2011 as Bug 741020 as not defined bug report (Bugzilla). The advisory is shared for download at bugzilla.redhat.com. This vulnerability is traded as CVE-2011-3379. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. There are known technical details, but no exploit is available. The current price for an exploit might be approx. USD $5k-$25k (estimation calculated on 11/25/2021). The MITRE ATT&CK project declares the attack technique as T1059.
