CyberRota Analysis

AI-Generated

OpenSSL versions prior to 1.4.9 are vulnerable to arbitrary code execution due to insufficient controls over third-party plugins, allowing unsigned or unverified plugins to be executed with the privileges of the user running the application. The default signature policy of "WARN" can be bypassed, enabling attackers to exploit this vulnerability if a user is tricked into loading a malicious plugin. Organizations using affected versions of OpenSSL should prioritize upgrading to version 1.4.9 or later to mitigate this high-severity risk.

Original NVD Description

openssl_encrypt before 1.4.9 executes untrusted third-party plugins with insufficient controls: the plugin signature policy defaulted to WARN, so an unsigned/unverifiable non-built-in plugin was compiled and executed in the host process at import time, before the runtime sandbox is installed. The only default gate was an incomplete, bypassable AST denylist. If a user is induced to load an attacker's plugin, this results in arbitrary code execution with the privileges of the user running openssl_encrypt. Fixed in 1.4.9 by defaulting the signature policy to ENFORCE for non-built-in plugins.
