The D-Link DCS series of Wi-Fi cameras contains a stack-based buffer overflow in alphapd, the camera's web server. The overflow allows a remotely authenticated attacker to execute arbitrary code by providing a long string in the WEPEncryption parameter when requesting wireless.htm. Vulnerable devices include DCS-5009L (1.08.11 and below), DCS-5010L (1.14.09 and below), DCS-5020L (1.15.12 and below), DCS-5025L (1.03.07 and below), DCS-5030L (1.04.10 and below), DCS-930L (2.16.01 and below), DCS-931L (1.14.11 and below), DCS-932L (2.17.01 and below), DCS-933L (1.14.11 and below), and DCS-934L (1.05.04 and below).

process alphapd↗

• → Monitor HTTP requests to /wireless.htm containing an abnormally long WEPEncryption parameter value, indicative of a stack-based buffer overflow exploitation attempt against D-Link DCS camera web server (alphapd). ↗
• → Target process to monitor for anomalous behavior or crashes is alphapd, the built-in web server on affected D-Link DCS cameras. ↗

• · Exploitation requires prior authentication; unauthenticated attackers cannot directly trigger the overflow. ↗
• · Affected firmware versions are device-specific; patch applicability must be verified per model (DCS-5009L ≤1.08.11, DCS-5010L ≤1.14.09, DCS-5020L ≤1.15.12, DCS-5025L ≤1.03.07, DCS-5030L ≤1.04.10, DCS-930L ≤2.16.01, DCS-931L ≤1.14.11, DCS-932L ≤2.17.01, DCS-933L ≤1.14.11, DCS-934L ≤1.05.04). ↗
