A vulnerability classified as critical has been found in D-Link DCS-5009, DCS-5010 and DCS-5020L (affected version not known). Affected is some unknown functionality of the file /setSystemAdmin of the component alphapd. The manipulation of the argument AdminID
with an unknown input leads to a command injection vulnerability. CWE is classifying the issue as CWE-77. The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:
On D-Link DCS-5009 devices with firmware 1.08.11 and earlier, DCS-5010 devices with firmware 1.14.09 and earlier, and DCS-5020L devices with firmware before 1.15.01, command injection in alphapd (binary responsible for running the camera's web server) allows remote authenticated attackers to execute code through sanitized /setSystemAdmin user input in the AdminID field being passed directly to a call to system.
