Title: YaSoft Switch Off Large Packet Remote Denial Of Service Vulnerability
Severity: MODERATE
Description:
Switch Off is a freely available remote PC management suite. It is available for the Microsoft Windows platform.
A vulnerability has been identified in the YaSoft Switch Off software package when handling large packets. This may make it possible for a remote user to deny service to legitimate users of the service.
The problem is in the handling of traffic on the management port. The software launches a service that binds to TCP port 8000, allowing remote users to connect via a web browser. However, when a request of 10240 bytes followed by two Carriage-Return and Line-Feed sequences (CRLF) is sent to the service, the software enters a loop that stops only when the process is terminated. The issue reportedly exists in 'swnet.dll'. A manual restart of the service is required to resume normal functionality.
