Published Oct 4, 2021EPSS 0.56%

Overview

CVE-2021-41285 is a high-severity vulnerability. It was published on October 4, 2021 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

Ballistix MOD Utility through 2.0.2.5 is vulnerable to privilege escalation in the MODAPI.sys driver component. The vulnerability is triggered by sending a specific IOCTL request that allows low-privileged users to directly interact with physical memory via the MmMapIoSpace function call (mapping physical memory into a virtual address space). Attackers could exploit this issue to achieve local privilege escalation to NT AUTHORITY\SYSTEM.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
