Text4Shell-Exploit - A Custom Python-based Proof-Of-Concept (PoC) Exploit Targeting Text4Shell (CVE-2022-42889), A Critical Remote Code Execution Vulnerability In Apache Commons Text Versions < 1.10
A Python-based proof-of-concept exploit exists for Text4Shell (CVE-2022-42889), a critical vulnerability in Apache Commons Text. This vulnerability allows remote code execution in Java applications using the StringSubstitutor class with interpolation enabled. Exploitation occurs through injection of malicious expressions within the vulnerable parameter, often through the data query parameter. The exploit leverages the ${script:...} syntax to execute arbitrary system commands. This specific PoC uses a reverse shell payload sent via a POST request. Users must adapt the payload and request path based on the target application. The exploit is intended for educational and authorized penetration testing only. It has been tested against Apache Commons Text versions prior to 1.10.0. Users should exercise caution and use it responsibly.
