CVE-2025-31969
📋 TL;DR
HCL Unica Platform has a misconfigured Content Security Policy (CSP) that could allow attackers to load malicious resources in users' browsers. This could lead to cross-site scripting (XSS) or clickjacking attacks against users accessing the platform. Organizations using HCL Unica Platform are affected.

⚠️ Risk & Real-World Impact
Worst Case
Attackers could execute arbitrary JavaScript in users' browsers, potentially stealing session cookies, credentials, or performing actions on behalf of authenticated users.
Likely Case
Limited XSS attacks that steal session data or perform clickjacking to trick users into unintended actions.
If Mitigated
Minimal impact with proper CSP headers and other web security controls in place.
🎯 Exploit Status
Exploitation requires the attacker to inject malicious content or manipulate CSP headers, typically requiring some level of access or user interaction.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Refer to HCL advisory KB0124417 for specific patched versions
Vendor Advisory: https://support.hcl-software.com/csm?id=kb_article&sysparm_article=KB0124417
Restart Required: No
Instructions:
1. Review HCL advisory KB0124417. 2. Apply the recommended patch or update to a fixed version. 3. Verify CSP headers are properly configured post-update.
🔧 Temporary Workarounds
Manual CSP Header Configuration
allManually configure Content Security Policy headers to restrict resource loading
Configure web server (e.g., Apache, Nginx) or application to set appropriate CSP headers
🧯 If You Can't Patch
- Implement web application firewall (WAF) rules to detect and block XSS attempts
- Deploy browser security extensions or policies that enforce CSP at the client level
🔍 How to Verify
Check if Vulnerable:
Check HTTP response headers for missing or weak Content-Security-Policy headers using browser developer tools or curl.
Check Version:
Check HCL Unica Platform version through admin interface or consult system documentation.
Verify Fix Applied:
Verify that Content-Security-Policy headers are present and properly configured in HTTP responses.
📡 Detection & Monitoring
Log Indicators:
- Unusual JavaScript execution patterns
- Multiple failed CSP violation reports
Network Indicators:
- HTTP requests with suspicious script sources in CSP headers
SIEM Query:
Search for web server logs containing CSP violation reports or unusual script loading patterns.
