VAR-200412-1188
Vulnerability from variot - Updated: 2025-04-03 22:30Stack-based buffer overflow in swnet.dll in YaSoft Switch Off 2.3 and earlier allows remote authenticated users to execute arbitrary code via a long message parameter in a SendMsg action to action.htm. A vulnerability has been identified in the YaSoft Switch Off software package when handling message requests. The buffer overrun condition exists in the 'swnet.dll' module of the software due to insufficient bounds checking performed by the affected component. The overflow may be caused by sending an excessively long 'message' parameter to the application. This may make it possible for a remote user to execute arbitrary code through a vulnerable server. Switch Off is an easy-to-use tray-based system tool that automates frequently used operations, such as shutting down or restarting a computer, closing a dial-up connection, and more. A remote attacker can use this vulnerability to overflow the buffer of the service program. Carefully submitting data may execute arbitrary instructions on the system with the SYSTEM process privilege. The problem exists in the action.htm script
