CVE-2026-2218Public exploitNetwork attack vector

Authenticated command execution via unsanitized AdminID

Published Feb 9, 2026 · Updated Feb 9, 2026

Command injection in D-Link DCS-933L firmware 1.14.0 through 1.14.11 allows remote authenticated users to execute OS commands. The alphapd setSystemAdmin handler takes AdminID from a POST request, strips only HTML whitespace, enforces a 1-to-12-character length, and inserts the remaining text directly into a shell command. Valid HTTP Digest administrator credentials are required; shell metacharacters can start services or run other commands with the camera's operating-system privileges.
