Description
A Zip Slip issue exists in the ISP Upgrade functionality of the WebUI. This occurs when the system fails to properly validate archives, allowing an authenticated administrator to perform arbitrary file writes via a crafted archive containing directory traversal sequences. Directory traversal is a technique used to access files and directories that are stored outside the web root folder. Successful exploitation can lead to the overwriting of arbitrary files on the underlying system, compromising system integrity and availability.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
