CVE-2026-2227Public exploitNetwork attack vector

Command execution via unsanitized AdminID parameter

Published Feb 9, 2026 · Updated Feb 9, 2026

Command injection in D-Link DCS-931L firmware 1.13.0 and earlier allows remote authenticated users to execute system commands. The doSystem function in /setSystemAdmin passes a manipulated AdminID argument to command processing without neutralizing command syntax. Exploitation requires high privileges and can read or alter camera data and interrupt its service through injected commands.
