CVE-2000-0441: Medium severity IBM AIX vulnerability
Vulnerability in AIX 3.2.x and 4.x allows local users to gain write access to files on locally or remotely mounted AIX filesystems.
Affected Software
Remediation
Recommended actions to resolve this vulnerability, in priority order.
- Configuration
Where feasible, mount locally or remotely mounted AIX filesystems as read-only to prevent local users from gaining write access until a vendor fix is available.
AIX filesystem mounts mount_mode = read-only - Configuration
Restrict or remove non-privileged users' ability to mount filesystems; allow mounting only by trusted administrators.
AIX system user_mount_privileges = restricted - Configuration
Unmount remote AIX filesystems that are not strictly required to eliminate the exposure from remotely mounted filesystems until a fix is available.
AIX filesystem mounts mounted_remote_filesystems = none/unmount_if_not_required - Compensating control
Restrict network access to hosts that export or access AIX filesystems using firewalls or ACLs; avoid mounting remote AIX filesystems from untrusted networks.
- Operational
Audit mounted AIX filesystems for unauthorized write operations, identify files modified by local users, and restore or remediate affected files and review local accounts for improper privileges.
