Name of the Vulnerable Software and Affected Versions D-Link DIR-X3260 (affected versions not specified)

Description This issue allows network-adjacent attackers to execute arbitrary code on affected installations of D-Link DIR-X3260 routers. Although authentication is required to exploit this issue, the existing authentication mechanism can be bypassed. The specific flaw exists within the prog.cgi component, 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 issue to execute code in the context of root.

Recommendations At the moment, there is no information about a newer version that contains a fix for this issue.
