VAR-202508-2757
Vulnerability from variot - Updated: 2025-09-20 23:12D-Link DCS-825L firmware version 1.08.01 and possibly prior versions contain an insecure implementation in the mydlink-watch-dog.sh script. The script monitors and respawns the dcp and signalc binaries without validating their integrity, origin, or permissions. An attacker with filesystem access (e.g., via UART or firmware modification) may replace these binaries to achieve persistent arbitrary code execution with root privileges. The issue stems from improper handling of executable trust and absence of integrity checks in the watchdog logic. D-Link Corporation of DCS-825L The firmware contains vulnerabilities related to privilege management, lack of authentication for critical functions, and insufficient integrity verification of downloaded code.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state
