CyberRota Analysis
AI-GeneratedThe rsync daemon versions prior to 3.5.0 are vulnerable to a denial of service attack that allows unauthenticated remote attackers to exhaust connection slots by manipulating the handshake process. This can lead to service disruption for legitimate users as attackers can maintain multiple connections without triggering timeouts. Organizations using affected versions of rsync should prioritize patching to mitigate this high-severity vulnerability.

Original NVD Description
rsync daemon 2.0.0 before 3.5.0 contains a denial of service vulnerability that allows unauthenticated remote attackers to exhaust daemon connection slots by stalling the handshake process before or after module selection without triggering the I/O timeout. Attackers can open many simultaneous connections and trickle data at the minimum rate to avoid timeout, or stall entirely before module selection where no timeout applies, consuming all available connection slots and denying service to legitimate clients.
