PHP Misconfiguration: Missing safe_mode_exec_dir Entry

Abstract

Configuring PHP to invoke arbitrary programs can allow attackers to execute malicious commands.

Explanation

When safe_mode is enabled, the safe_mode_exec_dir option restricts PHP to executing commands from only the specified directories. Although the absence of a safe_mode_exec_dir entry does not represent a security vulnerability itself, this added leniency can be exploited by attackers in conjunction with other vulnerabilities to make exploits more dangerous.
