What is CVE-2025-34048?

A path traversal vulnerability has been identified in the web management interface of several D-Link ADSL routers. This security flaw arises from insufficient input validation in the getpage parameter of the /cgi-bin/webproc CGI script. By exploiting this vulnerability, an unauthenticated remote attacker can execute crafted requests leading to unauthorized access to arbitrary files on the affected devices. This presents a significant risk for users of D-Link DSL-2730U, DSL-2750U, and DSL-2750E models with specified firmware versions.
