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.
