Description
Inadequate Encryption Strength vulnerability in TP-Link Archer C7 v5 and v5.8 (uhttpd modules) allows Password Recovery Exploitation. The web interface encrypts the admin password client-side using RSA-1024 before sending it to the router during login.
An adjacent attacker with the ability to intercept network traffic could potentially perform a brute-force or factorization attack against the 1024-bit RSA key to recover the plaintext administrator password, leading to unauthorized access and compromise of the device configuration. This issue affects Archer C7: through Build 20220715.
