Network Time Protocol Deja Vu: Broadcast Mode Replay Vulnerability

Summary Expected Behavior: RFC 5905 page 29 Section 8 states that the on-wire protocol resists replay of server response packet in broadcast mode. Also on page 55 section 15, the RFC claims security in authenticated mode against on-path attackers where an attacker can: a Intercept and archive...

Network Time Protocol ntpq Buffer Overflow Vulnerability

Network Time Protocol ntpq Control Protocol Replay Vulnerability

CERT VU357792 Summary The ntpq protocol is vulnerable to replay attacks. The sequence number being included under the signature fails to prevent replay attacks for two reasons. Commands that don’t require authentication can be used to move the sequence number forward, and NTP doesn’t actually car...

Network Time Protocol ntpq and ntpdc Infinite Loop Vulnerability

CERT VU357792 Summary ntpq processes incoming packets in a loop in getresponse. The loop’s only stopping conditions are receiving a complete and correct response or hitting a small number of error conditions.
