  • CVE-2013-1603: RTSP authentication bypass via hard-coded credentials — monitor RTSP DESCRIBE requests to D-Link IP cameras for sessions that succeed without valid user-supplied credentials, particularly where a previously stored authentication response is replayed.
  • Detect HTTP GET requests to /cgi-bin/rtpd.cgi with query strings containing shell metacharacters (semicolons, ampersands used as argument separators) indicative of OS command injection (CVE-2013-1599, same advisory).
  • ·The hard-coded backdoor credentials (CVE-2013-1603) enable RTSP video stream access; the exact credential values are not disclosed in the available source text — only the vulnerability class (CWE-798, Use of hard-coded credentials) is confirmed.
  • ·A wide range of D-Link firmware versions are affected; detection rules should not be scoped to a single firmware version. Other SKUs beyond those listed may also be vulnerable.
  • ·The PoC exploit code implements a TCP tunnel and UDP dispatcher to proxy RTSP traffic, meaning attack traffic may originate from a local proxy port rather than directly from the attacker's IP — network-layer attribution may be unreliable.
