CVE-2015-10141 PoC — Xdebug Remote Debugger Unauthenticated OS Command Execution

Title:Xdebug Remote Debugger Unauthenticated OS Command Execution (CVE-2015-10141)
Description:An unauthenticated OS command injection vulnerability exists within Xdebug versions 2.5.5 and earlier, a PHP debugging extension developed by Derick Rethans. When remote debugging is enabled, Xdebug listens on port 9000 and accepts debugger protocol commands without authentication. An attacker can send a crafted eval command over this interface to execute arbitrary PHP code, which may invoke system-level functions such as system() or passthru(). This results in full compromise of the host under the privileges of the web server user.

Xdebug <= 2.5.5 contains an unauthenticated command injection caused by accepting debugger protocol commands without authentication when remote debugging is enabled, letting remote attackers execute arbitrary PHP code and system commands, exploit requires remote debugging enabled.
