Lifecycle Timeline
3DescriptionCVE.org
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.

Technical ContextAI
This vulnerability is classified as Improper Privilege Management (CWE-269), which allows attackers to escalate privileges to gain unauthorized elevated access. 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. Affected products include: Dlink Dcs-825L Firmware.
RemediationAI
No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Apply principle of least privilege, validate privilege transitions, implement proper role separation.
