CVE-2025-58153
📋 TL;DR
This vulnerability causes hardware systems with a High-Speed Bridge (HSB) to lock up under specific undisclosed traffic conditions combined with external factors beyond attacker control. It affects F5 hardware systems with HSB components. Systems running software versions that have reached End of Technical Support are not evaluated for this vulnerability.
💻 Affected Systems
- F5 hardware systems with High-Speed Bridge (HSB)
⚠️ Risk & Real-World Impact
Worst Case
Complete system lockup requiring physical intervention and hardware reset, leading to extended service disruption and potential data loss.
Likely Case
Service disruption requiring manual intervention to restore functionality, with potential for partial system degradation.
If Mitigated
Minimal impact with proper monitoring and rapid response procedures in place.
🎯 Exploit Status
Exploitation requires specific undisclosed traffic conditions AND conditions beyond attacker's control, making reliable exploitation difficult.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not specified in CVE description - check vendor advisory
Vendor Advisory: https://my.f5.com/manage/s/article/K000151658
Restart Required: Yes
Instructions:
1. Review F5 advisory K000151658 for specific affected versions and patches. 2. Apply recommended firmware/software updates from F5. 3. Restart affected systems as required by the patch.
🔧 Temporary Workarounds
Traffic monitoring and rate limiting
allImplement traffic monitoring and rate limiting to prevent the specific conditions that trigger the HSB lockup.
Redundancy configuration
allConfigure redundant systems to maintain service availability if one system experiences HSB lockup.
🧯 If You Can't Patch
- Implement strict traffic monitoring and alerting for unusual traffic patterns
- Ensure redundant systems are properly configured and tested for failover scenarios
🔍 How to Verify
Check if Vulnerable:
Check system hardware for HSB components and review F5 advisory K000151658 for specific affected models and versions.Check Version:
System-specific commands vary by F5 platform - consult F5 documentation for version checking commands.Verify Fix Applied:
Verify patch installation through system version checks and monitor for HSB lockup events post-patch.📡 Detection & Monitoring
