Overview

The DCS-825L, including all models, Derivative Models, All Revisions, and All Firmware, has reached its End-of-Life (EOL)/End-of-Service Life (EOS) lifecycle. D-Link Corporation and D-Link North America (D-Link Systems, Inc.) recommend that all current users take one or more of the following actions:

1.             Transition to a current-generation product that has active firmware development and customer support.

2.             Perform comprehensive data backup.

3.             Contact our local regional office for further recommendations or information (LINK). 

By standard industry practice, products that have reached EOL/EOS status may no longer receive technical support or firmware updates. Please read the detailed information and recommendations provided below.

3rd Party Report information

Report 1:  08/22/2025 - CVE-2025-55581 - Link - F/W v1.08.01 - 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.

Report 2:  08/27/2025 - CVE-2025-55582 - Link - F/W v1.08.01 - 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.

Recommendation for End of Support /End of Life Products

From time to time, D-Link will determine that some of its products have reached the End of Support ("EOS") or End of Life (“EOL”). D-Link may choose to EOS/EOL a product due to the evolution of technology, market demands,   innovations, product efficiencies based on new technologies, or the product matures over time. It should be replaced by functionally superior technology.

For US Consumer

If a product has reached its End of Support ("EOS") and End of Life ("EOL"), there is usually no further extended support or development available for it.

Typically, for these products, D-Link will be unable to resolve device or firmware issues since all development and customer support have ceased. 

D-Link strongly recommends that this product be retired and cautions that any further use of this product may be a risk to devices connected to it. If US consumers continue to use these devices against D-Link's recommendation, please ensure the device has the most recent firmware, frequently update the device's unique password to access its web configuration, and always enable Wi-Fi encryption with a unique password.
