Better CVE-2022-29464
Certain WSO2 products allow unrestricted file upload with resultant remote code execution. The attacker must use a /fileupload endpoint with a Content-Disposition directory traversal sequence to reach a directory under the web root, such as a ../../../../repository/deployment/server/webapps directory.
Usage
python3 main.py https://example.com shell.jsp
Replace https://example.com with the vulnerable server and shell.jsp with a filename you want to use for upload.
Edit shell.jsp file as you want, but current shell works just fine too (better than other JSP shells, at least).
This shell can harvest output from stdout and stderr. CMDs are ran using /bin/sh.
Exposure
Mostly, sysadmins run WSO2 products as superuser. Using this exploit, you'll have superuser permissions over the whole system.
Database files are located at ~/repository/database directory.
- username: wso2carbon
- password: wso2carbon
- DBMS: H2 1.4.196
You can use the IntelliJ IDEA to open H2 type databases, like this.
Download files from the server
Using this exploit, you can copy any file from any directory to ~/repository/deployment/server/webapps/authenticationendpoint. authenticationendpoint directory serves JSP, but can be used to serve other files too.
Example:
cp ~/repository/database/WSO2CARBON_DB.h2.db ~/repository/deployment/server/webapps/authenticationendpoint/WSO2CARBON_DB.h2.db
This command will copy the main DB file to a directory we can use to download it from.
