Name of the Vulnerable Software and Affected Versions TG Soft Vir.IT eXplorer Lite version 8.5.65

Description The issue concerns a driver file, specifically VIRAGTLT.SYS, which does not validate input values from the IOCtl 0x82730068 endpoint. This lack of validation allows local users to potentially cause a denial of service, resulting in a Blue Screen of Death (BSOD), or possibly have other unspecified impacts.

Recommendations For TG Soft Vir.IT eXplorer Lite version 8.5.65, as a temporary workaround, consider restricting access to the VIRAGTLT.SYS driver file until a patch is available. Additionally, avoid using the IOCtl 0x82730068 endpoint in the affected driver file to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this issue.
