Technical ContextAI · show details

This vulnerability is classified as Out-of-bounds Write (CWE-787), which allows attackers to write data beyond allocated buffer boundaries leading to code execution or crashes. 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). Affected products include: Dlink Dcs-930L Firmware, Dlink Dcs-931L Firmware, Dlink Dcs-932L Firmware, Dlink Dcs-933L Firmware, Dlink Dcs-934L Firmware.

What every action level means

Emergency Immediate action required. Criteria: CRITICAL + in CISA KEV (actively exploited) without patch, OR CRITICAL + EPSS > 30% without patch, OR CRITICAL + active threat signals without patch.

Act Now Prioritize within 24-48h. Criteria: in KEV with patch available, OR CRITICAL + public POC, OR HIGH + EPSS > 10%, OR CRITICAL + active threat, OR any CRITICAL severity.

This Week Schedule remediation this week. Criteria: HIGH severity (CVSS 7.0-8.9). Patch within normal change window.

This Month Plan within 30 days. Criteria: MEDIUM severity (CVSS 4.0-6.9), lower exploitation probability. Include in regular patch cycle.

Monitor Track and reassess. Criteria: LOW severity (CVSS 0.1-3.9), minimal exploitation risk. No immediate action needed.

Attack Technique

Buffer Overflow HIGH

A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.

Memory Corruption HIGH

Memory corruption occurs when a program writes data beyond the boundaries of allocated memory regions or accesses memory in unintended ways, violating the integrity of the process's address space.

Remote Code Execution CRITICAL

Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
