CVE-2003-0863: PHP

High severity, CVSS 7.5. EPSS: 6.9% chance of exploitation in the next 30 days.

The php_check_safe_mode_include_dir function in fopen_wrappers.c of PHP 4.3.x returns a success value (0) when the safe_mode_include_dir variable is not specified in configuration, which differs from the previous failure value and may allow remote attackers to exploit file include vulnerabilities in PHP applications.

Affected products

• PHP PHP: version 4.3.0 only; version 4.3.1 only; version 4.3.2 only
