Attack-Flow Graph

Executive Summary

This vulnerability is in the OPSWAT AppRemover Driver (ardrv.sys) version 2017.10.02.1551 or earlier. It involves an issue in the IOCTL handler 0x2420031 where any local user can open the device and send process termination requests without proper privilege checks.

Detection Guidance

This vulnerability involves a local privilege escalation in OPSWAT AppRemover Driver (ardrv.sys) due to improper IOCTL handler validation. Detection requires checking for unauthorized process termination requests or unusual activity involving the driver. No specific commands are provided in the context, but monitoring for unexpected device interactions with ardrv.sys may help.

Impact Analysis

An attacker with local access could terminate arbitrary processes on the system, potentially disrupting critical applications or services. This could lead to denial of service, data loss, or unauthorized system changes depending on which processes are terminated.

Compliance Impact

This vulnerability allows local users to terminate processes without privilege validation, which could lead to unauthorized system modifications or data access. Such unauthorized access may violate compliance requirements under GDPR (data protection) and HIPAA (health information security) by enabling unauthorized data exposure or system manipulation.

Mitigation Strategies

Update OPSWAT AppRemover Driver to a version later than v2017.10.02.1551 to address the IOCTL handler privilege validation issue.
