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.
