Apache Apereo CAS Log4Shell Direct Check (CVE-2021-44228)

The version of Apache Apereo CAS running on the remote web server is affected by a remote code execution vulnerability in the bundled Apache Log4j logging library. Apache Log4j is vulnerable due to insufficient protections on message lookup substitutions when dealing with user controlled input. A remote, unauthenticated attacker can exploit this, via a web request, to execute arbitrary code with the permission level of the running Java process.

This plugin requires that both the scanner and target machine have internet access.
