CyberPanel 2.4.3 Authenticated Command Injection via starRemoteTransfer
CVSS 4.0
8.7High
Official description
CyberPanel 2.4.3, fixed in commit eca0c3c, contains an authenticated command injection vulnerability in the remote backup transfer feature that allows authenticated attackers to execute arbitrary OS commands by controlling a remote server's API response. Attackers can inject malicious commands through a crafted directory name in the remote server's API response, which bypasses security middleware validation and is passed unsanitized to the OS command execution function.
