[ Description ]Official description

getresetstatus in dns/views.py and ftp/views.py in CyberPanel (aka Cyber Panel) before 1c0c6cb allows remote attackers to bypass authentication and execute arbitrary commands via /dns/getresetstatus or /ftp/getresetstatus by bypassing secMiddleware (which is only for a POST request) and using shell metacharacters in the statusfile property, as exploited in the wild in October 2024 by PSAUX. Versions through 2.3.6 and (unpatched) 2.3.7 are affected.

CISA: CyberPanel contains an incorrect default permissions vulnerability that allows for authentication bypass and the execution of arbitrary commands using shell metacharacters in the statusfile property.
