CVE-2004-1063

NVD-CWE-noinfoPublished: January 10, 2005· Updated: Jun 16, 2026

10.0

CVSS v3.1

Official Description

PHP 4.x to 4.3.9, and PHP 5.x to 5.0.2, when running in safe mode on a multithreaded Unix webserver, allows local users to bypass safe_mode_exec_dir restrictions and execute commands outside of the intended safe_mode_exec_dir via shell metacharacters in the current directory name. NOTE: this issue was originally REJECTed by its CNA before publication, but that decision is in active dispute. This candidate may change significantly in the future as a result of further discussion.

Technical Analysis

CVE-2004-1063 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
