CVE-2021-34865
EUVD-2021-2151225.01.2022, 16:15
This vulnerability allows network-adjacent attackers to bypass authentication on affected installations of multiple NETGEAR routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the mini_httpd service, which listens on TCP port 80 by default. The issue results from incorrect string matching logic when accessing protected pages. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of root. Was ZDI-CAN-13313.Enginsight

Common Weakness Enumeration
- 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.
- CWE-697 - Incorrect ComparisonThe software compares two entities in a security-relevant context, but the comparison is incorrect, which may lead to resultant weaknesses.
