Technical details
A vulnerability exists in the cpdavd component of cPanel & WHM, specifically within the attachment download endpoints. The flaw stems from a combination of execution with unnecessary privileges (CWE-250) and insufficient path filtering. A remote, unauthenticated attacker can exploit this by sending specially crafted requests to the affected endpoints to bypass directory restrictions. This allows for the unauthorized reading of arbitrary files on the server's filesystem. cPanel has released a security update to address this issue.
