CVE-2025-1395
📋 TL;DR
This CVE describes an information disclosure vulnerability in HeyGarson software where error messages reveal sensitive information during fuzzing attacks. Attackers can use this to map application internals and identify potential attack vectors. All HeyGarson installations through version 30012026 are affected.
💻 Affected Systems
- Codriapp Innovation and Software Technologies Inc. HeyGarson
⚠️ 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.

⚠️ Risk & Real-World Impact
Worst Case
Attackers obtain detailed internal application information, system paths, database schemas, or authentication mechanisms, enabling targeted follow-on attacks like SQL injection or authentication bypass.
Likely Case
Attackers discover application structure, endpoints, and internal error handling, facilitating more precise attacks against the application.
If Mitigated
Limited information disclosure with no direct system compromise, though attackers gain reconnaissance advantages.
🎯 Exploit Status
Fuzzing tools can trigger error messages. No authentication required based on CWE-209 pattern.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available
Restart Required: No
Instructions:
No official patch available. Vendor has not responded to disclosure attempts.
🔧 Temporary Workarounds
Implement generic error handling
allConfigure application to return generic error messages without sensitive details
Application-specific configuration required
Web application firewall rules
allBlock requests that trigger verbose error responses
WAF-specific configuration required
🧯 If You Can't Patch
- Isolate HeyGarson behind reverse proxy with request filtering
- Implement network segmentation to limit access to HeyGarson instances
🔍 How to Verify
Check if Vulnerable:
Send malformed requests to HeyGarson endpoints and check if error responses contain internal paths, stack traces, or system informationCheck Version:
Application-specific - check HeyGarson version in admin interface or configuration filesVerify Fix Applied:
Test that error responses contain only generic messages without sensitive details📡 Detection & Monitoring
Log Indicators:
- Unusual error message patterns
- Multiple 500 errors with detailed information
- Requests with malformed parameters
Network Indicators:
- Unusual request patterns to application endpoints
- Fuzzing tool signatures in HTTP requests
