Analysis

Impact

A vulnerability has been identified in D‑Link DIR‑816 firmware version 1.10CNB05. The flaw exists within the goahead component’s redirect.asp file, where manipulating the token_id argument can bypass intended access controls. This improper authorization can allow an attacker to gain unauthorized administrative or configuration access to the device. The weakness is classified under CWE‑266 and CWE‑284.

Affected Systems

The affected product is the D‑Link DIR‑816 running firmware version 1.10CNB05. No other firmware versions or variants are explicitly stated as vulnerable in the CVE data.

Risk and Exploitability

The CVSS score of 6.9 indicates medium severity, while the EPSS score is reported as less than 1 %. The vulnerability is not listed in the CISA KEV catalog. Attack code is publicly available, and the exploit can be initiated remotely, which means that unsupported devices remain at a moderate to high risk until a firmware update is obtained or mitigations are applied.

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

OpenCVE Recommended Actions

Check the D‑Link website or contact support for a firmware update that addresses the redirect.asp access control flaw.
If an update is available, install it immediately on the DIR‑816 device.
If no firmware update exists, disable or restrict remote management functionality to trusted IP addresses only.
Monitor device logs for anomalous access attempts and consider blocking exploitation of the token_id parameter from external requests if possible.
