Description
A hard-coded cryptographic key vulnerability exists in TP-Link RE305 V3 and Archer C7 V5. The same RSA-1024 private key is stored within firmware configuration files and reused across devices. An attacker who obtains the private key and captures an HTTP Web UI login session may use the key to decrypt the administrator password. Successful exploitation may disclose the administrator password captured from an HTTP login session and compromise session confidentiality.
