CyberRota Analysis

AI-Generated

A vulnerability exists in the web module of TP-Link Archer AX55 v4 due to a hard-coded cryptographic key, allowing a local attacker to capture and decrypt the administrator password from an HTTP login session. This weakness compromises session confidentiality, making it easier for attackers to exploit the device. Network administrators using this router should prioritize remediation to protect against potential unauthorized access.

Original NVD Description

A hard-coded cryptographic key vulnerability exists in the web module of TP-Link Archer AX55 v4. A LAN attacker who captures an HTTP login session may use the known shared RSA private key to decrypt the administrator password; the weakened AES session key further reduces the effort required to compromise session confidentiality. Successful exploitation may disclose the administrator password captured from an HTTP login session and compromise session confidentiality.
