Attack-Flow Graph

Executive Summary

This is a vulnerability in Oracle Solaris 11.4's Filesystems component. It allows a low-privileged attacker with local access to compromise the system. Successful exploitation can lead to unauthorized data modification, deletion, or creation, and may cause the system to crash repeatedly or become unavailable.

Detection Guidance

This CVE affects Oracle Solaris 11.4 filesystems with low-privilege local access required for exploitation. Detection involves checking filesystem integrity and monitoring for unauthorized modifications. Review system logs for suspicious activity and verify file permissions. Use commands like 'pkg info' to check installed versions, 'zfs list' for filesystem snapshots, and 'auditctl' to enable filesystem auditing. Compare file checksums against known good states.

Impact Analysis

If you use Oracle Solaris 11.4, an attacker with local access could alter, delete, or create critical files without authorization. This could disrupt services, corrupt data, or make the system unusable, leading to downtime and potential data loss.

Compliance Impact

This vulnerability could lead to unauthorized data access or modification, violating GDPR's integrity and availability requirements or HIPAA's security rules. Compliance may be compromised if critical data is altered or lost due to exploitation.

Mitigation Strategies

Apply the latest Oracle Solaris patches from Oracle as soon as possible to address the vulnerability in the Filesystems component. Ensure only trusted users have logon access to systems running Oracle Solaris 11.4.
