What is CVE-2021-47949?

CyberPanel 2.1 is affected by a command execution vulnerability that enables authenticated attackers to exploit symlink attacks via the filemanager controller endpoint. By manipulating the completeStartingPath parameter in POST requests directed to /filemanager/controller, adversaries can create symbolic links allowing them to read sensitive files, including database credentials. Furthermore, through the /websites/fetchFolderDetails endpoint, attackers can execute arbitrary shell commands, potentially compromising the integrity of the system.

Affected Version(s)

CyberPanel <= 2.1

Exploit Proof of Concept (PoC)
