Security readout for executives and security teams
Plain-English summary
CVE-1999-1116 is an old local privilege escalation issue in SGI IRIX 6.3 and 6.4. A user with local access could gain root privileges through runpriv in the Indigo Magic System Administration subsystem. Business urgency is mainly for organizations still operating legacy SGI systems.
Executive priority
Treat as a legacy-system risk. Immediate action is warranted only if SGI IRIX 6.3 or 6.4 is still present. Focus on inventory, access restriction, isolation, and retirement planning.
Technical view
The CVE describes a vulnerability in runpriv within the Indigo Magic System Administration subsystem on SGI IRIX 6.3 and 6.4. The reported impact is local root privilege gain. No CVSS score, CWE, patch details, or exploit details are provided in the supplied sources.
Likely exposure
Exposure is likely limited to legacy environments running SGI IRIX 6.3 or 6.4. Systems without local user access are less exposed. Modern environments are unlikely to be affected unless they retain SGI IRIX hosts for specialized workloads.
Exploitation context
The vulnerability requires local user access according to the CVE description. The provided sources do not state active exploitation, and this CVE is not listed as KEV in the supplied data.
Researcher notes
Evidence is sparse. The public CVE record and X-Force reference identify local root privilege escalation but do not provide scoring, root cause detail, affected package versions, exploit status, or patch identifiers in the supplied bundle.
Mitigation direction
- Inventory for SGI IRIX 6.3 and 6.4 systems.
- Restrict local shell access on affected legacy hosts.
- Review SGI or IBM X-Force historical guidance for vendor-specific remediation.
- Prioritize retirement or isolation of unsupported IRIX systems.
Validation and detection
- Confirm whether any SGI IRIX 6.3 or 6.4 hosts remain in service.
- Check whether the Indigo Magic System Administration subsystem is installed.
- Review local account access and administrative privilege boundaries.
- Document compensating controls for any system that cannot be patched or retired.
