Action Type Old Value New Value Changed Description GoAhead before 5.1.2 mishandles the nonce value during Digest authentication. This may permit request replay attacks for local requests over HTTP. The HTTP Digest Authentication in the GoAhead web server before 5.1.2 does not completely protect against replay attacks. This allows an unauthenticated remote attacker to bypass authentication via capture-replay if TLS is not used to protect the underlying communication channel. -
