What is CVE-2015-10141?
CVE-2015-10141 is a critical command injection vulnerability in Xdebug, published on 23 Jul 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official 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.
