CVE-2025-51308
📋 TL;DR
In Gatling Enterprise versions below 1.25.0, low-privileged users without admin roles can access read-only REST API endpoints due to missing authorization checks, allowing unauthorized information collection. This affects all deployments using vulnerable versions where non-admin users have access to the application.
💻 Affected Systems
- Gatling Enterprise
📦 What is this software?
Gatling by Gatling
⚠️ Risk & Real-World Impact
Worst Case
An attacker with low-privileged access could enumerate sensitive system information, user data, or configuration details that could facilitate further attacks or data exfiltration.
Likely Case
Internal users or compromised low-privileged accounts accessing information they shouldn't have permission to view, potentially exposing operational data or system details.
If Mitigated
With proper network segmentation and access controls, impact is limited to information disclosure within the application's data scope accessible to low-privileged users.
🎯 Exploit Status
Exploitation requires authenticated low-privileged access and knowledge of API endpoints.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 1.25.0 or later
Vendor Advisory: https://gatling.io/products
Restart Required: No
Instructions:
1. Backup current configuration. 2. Download Gatling Enterprise 1.25.0 or later from official sources. 3. Follow vendor upgrade documentation. 4. Verify authorization checks are functioning.
🔧 Temporary Workarounds
Network Access Restriction
allRestrict network access to Gatling Enterprise API endpoints to only authorized users or systems.
API Endpoint Monitoring
allImplement monitoring and alerting for unauthorized API access attempts by non-admin users.
🧯 If You Can't Patch
- Implement strict network segmentation to isolate Gatling Enterprise from untrusted networks.
- Review and minimize low-privileged user accounts and monitor their API access patterns.
🔍 How to Verify
Check if Vulnerable:
Check Gatling Enterprise version via web interface or configuration files. If version is below 1.25.0, system is vulnerable.Check Version:
Check web interface or consult gatling-enterprise configuration files for version information.Verify Fix Applied:
After upgrading to 1.25.0 or later, test that low-privileged users cannot access read-only API endpoints they shouldn't have access to.📡 Detection & Monitoring
Log Indicators:
