CVE-2025-52629
📋 TL;DR
HCL AION 2.0 lacks a Content-Security-Policy header, which could allow attackers to execute malicious scripts or inject unauthorized content in web pages. This affects all deployments of HCL AION version 2.0 that haven't implemented CSP headers through other means.

⚠️ Risk & Real-World Impact
Worst Case
Successful cross-site scripting attacks leading to session hijacking, credential theft, or complete compromise of user accounts and data.
Likely Case
Limited content injection or script execution that could deface pages or steal limited user data.
If Mitigated
Minimal impact if other security controls like input validation and output encoding are properly implemented.
🎯 Exploit Status
Exploitation requires finding other injection vulnerabilities first; CSP absence makes those easier to exploit.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check vendor advisory for specific patch version
Vendor Advisory: https://support.hcl-software.com/csm?id=kb_article&sysparm_article=KB0127972
Restart Required: Yes
Instructions:
1. Review vendor advisory KB0127972
2. Apply recommended patch from HCL
3. Restart AION services
4. Verify CSP headers are present
🔧 Temporary Workarounds
Manual CSP Header Implementation
allAdd Content-Security-Policy headers through web server configuration or application settings
For Apache: Header set Content-Security-Policy "default-src 'self'"
For Nginx: add_header Content-Security-Policy "default-src 'self';";
🧯 If You Can't Patch
- Implement web application firewall with CSP injection capability
- Deploy reverse proxy that adds CSP headers to responses
🔍 How to Verify
Check if Vulnerable:
Use browser developer tools or curl to check HTTP response headers for missing Content-Security-Policy headerCheck Version:
Check AION administration console or configuration files for version informationVerify Fix Applied:
Verify Content-Security-Policy header appears in HTTP responses with appropriate directives📡 Detection & Monitoring
Log Indicators:
- Unusual script execution patterns
- Unexpected content modifications
Network Indicators:
- HTTP responses without CSP headers
- Suspicious script sources in page loads
SIEM Query:
http.response.headers NOT Content-Security-Policy AND dest_port IN (80, 443) AND dest_ip IN (AION_SERVERS)
