An unauthenticated denial-of-service issue exists due to improper handling of exceptional request conditions, which can lead to a NULL pointer dereference (a situation where the software attempts to read from a memory address that is null, causing a crash). A remote attacker on an adjacent network can send a specially crafted HTTP request to crash the HTTP service process, rendering the web management interface and HTTP-dependent functionality temporarily unavailable.

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.
