📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal administrator session cookies, perform actions as authenticated users, deface websites, or redirect users to malicious sites.
Likely Case
Attackers with low privileges could steal session tokens from other users, perform limited actions within their permission scope, or deploy credential harvesting pages.
If Mitigated
With proper input validation and output encoding, malicious scripts would be neutralized before reaching victim browsers.
🎯 Exploit Status
Exploitation requires authenticated low-privileged access and knowledge of vulnerable form fields.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 6.5.24 or later
Vendor Advisory: https://helpx.adobe.com/security/products/experience-manager/apsb25-115.html
Restart Required: Yes

allImplement server-side input validation to sanitize form field inputs before storage.
Implement custom servlet filter or use AEM's built-in XSS protection features
Content Security Policy
allDeploy strict Content Security Policy headers to limit script execution.
Add 'Content-Security-Policy: script-src 'self'' to HTTP responses
🧯 If You Can't Patch
- Implement web application firewall (WAF) rules to block XSS payloads in form submissions
- Review and restrict low-privileged user access to form editing capabilities
🔍 How to Verify
Check if Vulnerable:
Check AEM version via CRXDE Lite or system console. If version is 6.5.23 or earlier, system is vulnerable.Check Version:
curl -u admin:password http://localhost:4502/system/console/status-productinfo.json | grep 'Adobe Experience Manager'Verify Fix Applied:
After patching, verify version is 6.5.24 or later and test form fields with XSS payloads to ensure they're properly sanitized.📡 Detection & Monitoring
