Vulnerability from fkie_nvd - Published: 2025-08-27 20:15 - Updated: 2025-09-09 15:20
Severity ?
Summary
D-Link DCS-825L firmware v1.08.01 contains a vulnerability in the watchdog script `mydlink-watch-dog.sh`, which blindly respawns binaries such as `dcp` and `signalc` without verifying integrity, authenticity, or permissions. An attacker with local filesystem access (via physical access, firmware modification, or debug interfaces) can replace these binaries with malicious payloads. The script executes these binaries as root in an infinite loop, leading to persistent privilege escalation and arbitrary code execution. This issue is mitigated in v1.09.02, but the product is officially End-of-Life and unsupported.

Un atacante con acceso al sistema de archivos local (mediante acceso f\u00edsico, modificaci\u00f3n del firmware o interfaces de depuraci\u00f3n) puede reemplazar estos archivos binarios con payloads maliciosos. El script ejecuta estos archivos binarios como root en un bucle infinito, lo que provoca una escalada persistente de privilegios y la ejecuci\u00f3n de c\u00f3digo arbitrario. Este problema se ha mitigado en la v1.09.02, pero el producto ha finalizado oficialmente su ciclo de vida y no recibe soporte."
