CVE-2024-4190
📋 TL;DR
Stored Cross-Site Scripting (XSS) vulnerabilities in OpenText ArcSight Logger allow attackers to inject malicious scripts that persist in the application and execute when other users view affected pages. This could lead to session hijacking, data theft, or unauthorized actions performed on behalf of legitimate users. Organizations using vulnerable versions of ArcSight Logger are affected.
💻 Affected Systems
- OpenText ArcSight Logger
⚠️ 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).

- Review the CVE details at 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 steal administrator credentials, compromise the entire ArcSight Logger instance, pivot to other systems, and maintain persistent access to sensitive security logs and infrastructure.
Likely Case
Attackers inject malicious JavaScript to steal session cookies, redirect users to phishing sites, or perform unauthorized actions within the ArcSight Logger interface.
If Mitigated
With proper input validation, output encoding, and Content Security Policy (CSP) headers, the impact is limited to potential UI disruption without data compromise.
🎯 Exploit Status
Stored XSS typically requires some level of access to input fields, but exploitation is straightforward once access is obtained.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check vendor advisory for specific patched versions
Vendor Advisory: https://portal.microfocus.com/s/article/KM000030655
Restart Required: Yes
Instructions:
1. Review vendor advisory KM000030655. 2. Download and apply the latest security patch from OpenText. 3. Restart ArcSight Logger services. 4. Verify the patch is applied successfully.
🔧 Temporary Workarounds
Implement Content Security Policy
allAdd CSP headers to restrict script execution sources
Add to web server configuration: Content-Security-Policy: default-src 'self'; script-src 'self'
Input Validation Rules
allConfigure WAF or application firewall to block XSS patterns
Configure WAF rules to detect and block <script>, javascript:, and other XSS patterns
🧯 If You Can't Patch
- Isolate ArcSight Logger instance from internet access
- Implement strict access controls and monitor for suspicious input patterns
🔍 How to Verify
Check if Vulnerable:
Check ArcSight Logger version against vendor advisory; test input fields for script injectionCheck Version:
Check ArcSight Logger web interface or installation directory for version informationVerify Fix Applied:
Verify patch version is installed and test previously vulnerable input fields📡 Detection & Monitoring
Log Indicators:
- Unusual input patterns containing script tags or JavaScript in web logs
- Multiple failed input validation attempts
Network Indicators:
- HTTP requests containing suspicious script payloads to ArcSight Logger endpoints
SIEM Query:
source="arcsight_logger" AND (http_uri CONTAINS "<script>" OR http_body CONTAINS "javascript:")
