ZDI-23-1519: (0Day) D-Link DIR-X3260 SetTriggerPPPoEValidate Username Command Injection Remote Code Execution Vulnerability

First published: Wed Oct 04 2023(Updated: )

This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of D-Link DIR-X3260 routers. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the prog.cgi program, which handles HNAP requests made to the lighttpd webserver listening on TCP ports 80 and 443. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of root.
