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. The specific flaw exists within the prog.cgi binary, which handles HNAP requests made to the lighttpd webserver. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. An attacker can leverage this vulnerability 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 vulnerability.
