CVE-2025-64833
📋 TL;DR
Adobe Experience Manager versions 6.5.23 and earlier contain a stored cross-site scripting vulnerability in form fields. Low-privileged attackers can inject malicious JavaScript that executes in victims' browsers when they visit compromised pages. This affects organizations using vulnerable AEM instances for content management.
💻 Affected Systems
- Adobe Experience Manager
📦 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
Session hijacking of low-privileged users, credential theft, or limited website defacement through injected content.
If Mitigated
Limited impact with proper input validation and output encoding, though some user data exposure may still occur.
🎯 Exploit Status
Requires authenticated access but low technical skill to exploit once access is obtained.
🛠️ 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
Instructions:
1. Download AEM 6.5.24 or later from Adobe's distribution portal. 2. Apply the service pack following Adobe's upgrade documentation. 3. Restart the AEM instance. 4. Verify the update completed successfully.
🔧 Temporary Workarounds
Input Validation Filter
allImplement custom servlet filters to sanitize form field inputs before processing.
Implement Java servlet filter with OWASP Java Encoder library for input sanitization
Content Security Policy
allDeploy strict CSP headers to limit script execution sources.
Add 'Content-Security-Policy: script-src 'self'' to HTTP response headers
🧯 If You Can't Patch
- Restrict low-privileged user access to form editing capabilities
- Implement web application firewall rules to block XSS payload patterns
🔍 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 | grep 'Adobe Experience Manager'Verify Fix Applied:
Verify AEM version is 6.5.24 or later and test form fields with basic XSS payloads like <script>alert('test')</script>.📡 Detection & Monitoring
Log Indicators:
- Unusual form submissions with script tags
- Multiple failed login attempts followed by form submissions
- Requests containing common XSS payload patterns
Network Indicators:
- HTTP requests with encoded script tags in form parameters
- Unusual outbound connections after form submissions
SIEM Query:
source="aem-access.log" AND ("<script" OR "javascript:" OR "onerror=" OR "onload=")
