⚠️ Risk & Real-World Impact

🔴

Worst Case

Attackers could steal session cookies, perform actions as authenticated users, redirect to malicious sites, or deface the portal interface.

🟠

Likely Case

Attackers steal session cookies or authentication tokens to hijack user sessions and gain unauthorized access to portal functions.

🟢

If Mitigated

With proper input validation and output encoding, malicious scripts would be neutralized before reaching users' browsers.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: LOW

XSS vulnerabilities typically require user interaction or social engineering to trigger, but exploitation is technically straightforward once the injection point is identified.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 12.0.3 and 11.9.3

Vendor Advisory: https://security.intrexx.com/en/security-advisories/ixsa-20250310-02/

Restart Required: Yes

1. Download the latest version from the Intrexx customer portal. 2. Backup your current installation. 3. Apply the update following Intrexx upgrade procedures. 4. Restart the portal server.

🔧 Temporary Workarounds

Input Validation Filter

all

Implement server-side input validation to sanitize user input before processing by Velocity scripts.

Content Security Policy

all

Implement strict Content Security Policy headers to restrict script execution sources.

Add 'Content-Security-Policy: script-src 'self'' to HTTP headers

🧯 If You Can't Patch

  • Implement Web Application Firewall (WAF) rules to detect and block XSS payloads
  • Disable or restrict access to affected Velocity script functionality if not required

🔍 How to Verify

Check if Vulnerable:

Check the portal version in the administration interface or by examining the installation directory version files.

Check Version:

Check the version.txt file in the Intrexx installation directory or use the portal administration interface.

Verify Fix Applied:

Verify the portal version shows 12.0.3 or higher, or 11.9.3 or higher after patching.

📡 Detection & Monitoring

Log Indicators:

  • Unusual script tags or JavaScript in request parameters
  • Multiple failed XSS attempts in web server logs

Network Indicators:

  • HTTP requests containing suspicious script patterns or encoded payloads

SIEM Query:

web_requests WHERE (url CONTAINS '<script' OR parameters CONTAINS 'javascript:' OR parameters CONTAINS 'onload=' OR parameters CONTAINS 'onerror=')
