CVE-2025-52624
📋 TL;DR
This vulnerability allows attackers to bypass script allowlist configurations in HCL AION due to an incorrectly configured Content-Security-Policy header. This could enable unauthorized script execution, potentially leading to cross-site scripting and other injection attacks. It affects HCL AION version 2.0.

⚠️ Risk & Real-World Impact
Worst Case
Attackers could execute arbitrary scripts in user browsers, leading to session hijacking, credential theft, or complete compromise of user accounts and data.
Likely Case
Cross-site scripting attacks that steal session cookies or perform unauthorized actions on behalf of authenticated users.
If Mitigated
With proper CSP headers and input validation, the risk is significantly reduced to low-level information disclosure.
🎯 Exploit Status
Exploitation requires understanding of CSP bypass techniques and access to inject malicious scripts.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check vendor advisory for specific patched version
Vendor Advisory: https://support.hcl-software.com/csm?id=kb_article&sysparm_article=KB0124444
Restart Required: No
Instructions:
1. Review the HCL advisory KB0124444
2. Apply the recommended patch or update
3. Verify CSP headers are properly configured
4. Test for script execution bypass
🔧 Temporary Workarounds
Strengthen Content-Security-Policy
allManually configure strict CSP headers to prevent script execution bypass
Configure 'script-src' directive to only allow trusted sources
Implement 'unsafe-inline' and 'unsafe-eval' restrictions
Add 'strict-dynamic' if supported
🧯 If You Can't Patch
- Implement web application firewall rules to block suspicious script injection patterns
- Enable additional browser security headers like X-Content-Type-Options and X-Frame-Options
🔍 How to Verify
Check if Vulnerable:
Inspect HTTP response headers for Content-Security-Policy configuration and test script injection bypass techniquesCheck Version:
Check AION administration interface or configuration files for version informationVerify Fix Applied:
Verify CSP headers are properly configured and test that unauthorized scripts cannot execute📡 Detection & Monitoring
