CVE-2020-8863
23.03.2020, 21:15
This vulnerability allows network-adjacent attackers to bypass authentication on affected installations of D-Link DIR-867, DIR-878, and DIR-882 routers with firmware 1.10B04. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of HNAP login requests. The issue results from the lack of proper implementation of the authentication algorithm. An attacker can leverage this vulnerability to escalate privileges and execute code in the context of the router. Was ZDI-CAN-9470.Enginsight

Common Weakness Enumeration
- CWE-303 - Incorrect Implementation of Authentication AlgorithmThe requirements for the software dictate the use of an established authentication algorithm, but the implementation of the algorithm is incorrect.
- CWE-287 - Improper AuthenticationWhen an actor claims to have a given identity, the software does not prove or insufficiently proves that the claim is correct.
