This is a PoC exploit for CVE-2021-44228, a remote code execution vulnerability in the Apache Log4j logging library. The repository, mirrors_yahoo/check-log4j, contains a tool called check-log4j that attempts to determine if a host is vulnerable to this vulnerability by looking for the presence of the vulnerable Log4j version in running Java processes and inside Java archive files. The tool is designed to be non-intrusive and does not attempt to exploit the vulnerability, but rather to provide a way for host owners to determine if they have a vulnerable version of Log4j on their system. The tool can be installed and run on a system to check for vulnerability, and it provides a manual page with details on how to use it.
