- CWE-321
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.
