Name of the Vulnerable Software and Affected Versions 2345 Security Guard version 3.6

Description The issue allows local users to cause a denial of service (BSOD) or possibly have unspecified other impact. This is due to the driver file (2345NetFirewall.sys) not validating input values from IOCtl 0x00222040.

Recommendations For 2345 Security Guard version 3.6, consider updating to a newer version that addresses the issue of not validating input values from IOCtl 0x00222040, if available. As a temporary workaround, restrict access to the 2345NetFirewall.sys driver file to minimize the risk of exploitation.
