CVE-2025-1091
📋 TL;DR
This CVE describes a broken authorization vulnerability where authenticated users can download IOA script and configuration files by knowing specific URLs. This affects systems running vulnerable versions of the affected software where users have authenticated access but shouldn't have access to these sensitive files.
💻 Affected Systems
- Tenable IOA (Indicators of Attack)
⚠️ Manual Verification Required
This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.
Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

- Check vendor security advisories for your specific version
- Test if the vulnerability is exploitable in your environment
- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Attackers could exfiltrate sensitive IOA scripts and configurations, potentially revealing security controls, detection logic, or enabling further attacks by understanding the security posture.
Likely Case
Insider threats or compromised accounts accessing sensitive configuration data that should be restricted, potentially leading to information disclosure about security controls.
If Mitigated
With proper access controls and monitoring, impact is limited to authorized users accessing files they shouldn't, which can be detected and investigated.
🎯 Exploit Status
Exploitation requires authenticated access and knowledge of specific URLs; no public exploit code identified
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Refer to Tenable advisory TNS-2025-01 for specific patched versions
Vendor Advisory: https://www.tenable.com/security/tns-2025-01
Restart Required: Yes
Instructions:
1. Review Tenable advisory TNS-2025-01
2. Identify affected Tenable IOA versions
3. Apply the security update provided by Tenable
4. Restart affected services as required
🔧 Temporary Workarounds
Restrict Access to IOA Management Interfaces
allLimit network access to Tenable IOA management interfaces to only authorized administrative networks
Implement Additional Access Controls
allUse network segmentation or web application firewalls to add additional authorization checks for IOA file access
🧯 If You Can't Patch
- Implement strict network segmentation to isolate Tenable IOA management interfaces
- Enhance monitoring and alerting for unusual file access patterns to IOA resources
🔍 How to Verify
Check if Vulnerable:
Check Tenable IOA version against advisory TNS-2025-01; test authenticated access to IOA script/config URLs that should be restrictedCheck Version:
Check Tenable IOA version through administrative interface or consult Tenable documentationVerify Fix Applied:
Verify Tenable IOA is updated to patched version per advisory; test that authenticated users can no longer access restricted IOA files📡 Detection & Monitoring
Log Indicators:
- Unauthorized access attempts to IOA script/config file paths
- Multiple file download requests from single authenticated user
- Access to sensitive IOA URLs from non-admin accounts
Network Indicators:
- Unusual volume of requests to IOA file endpoints
- Patterns of file downloads from IOA interfaces
