CVE-2023-35724
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedD-Link DAP-2622 Telnet CLI Use of Hardcoded Credentials Authentication Bypass Vulnerability. This vulnerability allows network-adjacent attackers to bypass authentication on affected installations of D-Link DAP-2622 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the CLI service, which listens on TCP port 23. The server program contains hard-coded credentials. An attacker can leverage this vulnerability to bypass authentication on the system. . Was ZDI-CAN-20050.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysisA password or key is baked into the source or binary, so anyone who obtains the code obtains the credential. These are trivially found once the software is distributed. Remediation means removing the secret, rotating it, and loading credentials from secured configuration at runtime.
