Security readout for executives and security teams
Plain-English summary
CVE-2000-1193 is a denial-of-service issue in the PMCD service within Performance Co-Pilot on IRIX 6.x. A remote attacker could send an extremely long string to the PMCD port and cause resource exhaustion. This is mainly a concern for organizations still running exposed legacy IRIX systems.
Executive priority
Treat this as a legacy-system risk. It is not supported by evidence of active exploitation, but exposed IRIX 6.x PMCD services could be disrupted remotely. Prioritize if these systems support production, safety, or regulated workflows.
Technical view
The CVE describes resource exhaustion in Performance Metrics Collector Daemon (PMCD) in Performance Co-Pilot for IRIX 6.x. The trigger is an extremely long string sent remotely to the PMCD port. Public source data does not provide CVSS, CWE, patch details, or deeper protocol-level impact.
Likely exposure
Exposure is likely limited to legacy IRIX 6.x systems with Performance Co-Pilot PMCD enabled and reachable over the network. Internet exposure would raise urgency, but the provided sources do not show current exposure data.
Exploitation context
The issue is remotely reachable when the PMCD port is accessible. The source bundle does not indicate active exploitation, public exploit availability, or inclusion in CISA KEV. Impact is described as denial of service through resource exhaustion, not code execution.
Researcher notes
Evidence is sparse and old. The CVE record states IRIX 6.x, Performance Co-Pilot PMCD, remote denial of service, and long-string resource exhaustion. No CVSS, affected CPEs, exploit status, or vendor fix is included in the provided sources.
Mitigation direction
- Identify any IRIX 6.x systems running Performance Co-Pilot PMCD.
- Restrict PMCD access to trusted management networks only.
- Disable PMCD where it is not required for operations.
- Check legacy SGI/IRIX support guidance for any available fixes or advisories.
- Monitor exposed legacy systems for abnormal PMCD resource usage.
Validation and detection
- Inventory IRIX 6.x hosts and confirm whether PMCD is installed or enabled.
- Verify PMCD is not reachable from untrusted networks.
- Review firewall rules controlling access to the PMCD service.
- Check system logs for PMCD crashes, hangs, or resource exhaustion symptoms.
- Document business owners for any remaining IRIX dependencies.
