Security readout for executives and security teams
Plain-English summary
CVE-1999-0313 is an old local privilege escalation issue in SGI IRIX 6.4 S2MP on Origin/Onyx2 systems. A local user could reportedly abuse relative path handling in disk_bandwidth to gain root access. Business urgency is mainly for organizations still operating legacy SGI IRIX environments.
Executive priority
Prioritize if legacy SGI IRIX systems remain in production or support sensitive operations. The issue can lead to root access, but requires local access and affects a very old platform. If no such systems exist, document non-exposure and close.
Technical view
The CVE describes disk_bandwidth on SGI IRIX 6.4 S2MP for Origin/Onyx2 allowing local users to gain root access through relative pathnames. Public details are sparse, and the provided sources do not include CVSS, CWE, patch status, or detailed vendor remediation.
Likely exposure
Exposure appears limited to legacy SGI IRIX 6.4 S2MP deployments on Origin/Onyx2 systems where local shell access exists. Modern environments are unlikely to be affected unless they retain these systems for specialized workloads or archival operations.
Exploitation context
The source bundle supports local privilege escalation, not remote compromise. CISA KEV status is false in the provided data, and no cited source confirms active exploitation. Practical risk depends on whether untrusted or lower-privileged users can access affected IRIX hosts.
Researcher notes
Evidence is limited to the CVE description and IBM X-Force reference. No exploit details, CVSS vector, CWE mapping, or official fix information are included in the provided sources. Avoid assuming affected versions beyond SGI IRIX 6.4 S2MP for Origin/Onyx2.
Mitigation direction
- Inventory any SGI IRIX 6.4 S2MP Origin/Onyx2 systems.
- Check SGI or trusted archival vendor guidance for patches or advisories.
- Restrict local shell access to trusted administrators only.
- Apply least privilege and monitor privileged account activity.
- Consider isolating legacy IRIX systems from general user networks.
Validation and detection
- Confirm whether any Origin/Onyx2 systems run IRIX 6.4 S2MP.
- Determine whether disk_bandwidth is present and accessible to local users.
- Review local accounts for unnecessary interactive access.
- Check system documentation for applied SGI security updates.
- Record compensating controls if vendor fixes are unavailable.
