CVE-2006-6383 EXPLOIT

4.6
MEDIUM · CVSS 2.0 · EPSS 1.1% (pctl 66)

Patch early

A public exploit exists.

Description

PHP 5.2.0 and 4.4 allows local users to bypass safe_mode and open_basedir restrictions via a malicious path and a null byte before a ";" in a session_save_path argument, followed by an allowed path, which causes a parsing inconsistency in which PHP validates the allowed path but sets session.save_path to the malicious path.
