Microsoft NetMeeting RDS local session hijacking

netmeeting-rds-session-hijacking (10119) The risk level is classified as MediumMedium Risk


Microsoft NetMeeting could allow a local attacker to hijack a remote user's sessions when the Remote Desktop Sharing (RDS) feature is being used. A local attacker could monitor an RDS session and when the remote user makes a change to a file or setting, the attacker could then enter CTRL-ALT-DEL to initiate a system shut down. This would cause control over the system to be returned to the local user, which would allow the attacker to gain unauthorized access to the system with the same privileges as the remote user.
