CVE-2022-44801

Vulnerability

The D-Link DIR-878 router running firmware version 1.02B05 contains an incorrect access control vulnerability [1]. The issue resides in the router's web management interface, where access control checks are insufficiently enforced. An attacker who is already on the local network may be able to bypass authentication or privilege checks to access restricted functions or data.

Exploitation

An attacker must be on the same local network as the vulnerable router and be able to reach the web management interface [1]. No other specific preconditions are disclosed in the available references. The exact sequence of steps to trigger the vulnerability is not provided in the public information.

Impact

Successful exploitation could allow an attacker to gain unauthorized access to router configuration settings or other protected resources [1]. The exact CIA impact (confidentiality, integrity, availability) is not detailed in the available references, but given the nature of an access control flaw, potential outcomes include information disclosure and unauthorized modification of device settings.

Mitigation

D-Link's security bulletin advises users to check for firmware updates and follow the vendor's security guidance [1]. As of the publication date (2022-11-22), no specific patched version has been identified in the available references. Users should monitor the D-Link support page for future firmware releases. If the device is end-of-life (EOL), no fix may be available, and replacement is recommended.
