| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Ballistix MOD Utility versions 2.0.2.5 and earlier
Description
The issue is related to a privilege escalation vulnerability in the MODAPI.sys driver component. It is triggered by sending a specific IOCTL request, allowing low-privileged users to directly interact with physical memory via the
MmMapIoSpace function call, which maps physical memory into a virtual address space. This could enable attackers to achieve local privilege escalation to NT AUTHORITYSYSTEM. The vulnerability is associated with inadequate access control in the MmMapIoSpace function.Recommendations
For Ballistix MOD Utility versions 2.0.2.5 and earlier, as a temporary workaround, consider disabling the
MmMapIoSpace function until a patch is available. Restrict access to the MODAPI.sys driver component to minimize the risk of exploitation. Avoid using the IOCTL request that triggers the vulnerability in the affected driver component until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.Exploit
