CVE-2025-64622
📋 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
Low-privileged users could escalate privileges, steal session data from other users, or perform limited client-side attacks.
If Mitigated
With proper input validation and output encoding, the vulnerability would be prevented despite the underlying code flaw.
🎯 Exploit Status
Exploitation requires authenticated low-privileged access. The vulnerability is in form fields where user input is not properly sanitized.
🛠️ 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. Follow Adobe's upgrade documentation for your deployment type (on-premise or cloud). 3. Apply the update package. 4. Restart AEM services. 5. Verify the update completed successfully.
🔧 Temporary Workarounds
Input Validation Filter
allImplement custom servlet filters to sanitize form field input before processing
Implement Java servlet filter with OWASP Java Encoder library for XSS prevention
Content Security Policy
allDeploy strict CSP headers to mitigate script execution even if injection occurs
Add 'Content-Security-Policy: default-src 'self'; script-src 'self'' to HTTP responses
🧯 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:
After patching, verify version is 6.5.24 or later. Test form fields with basic XSS payloads to confirm sanitization.📡 Detection & Monitoring
Log Indicators:
- Unusual form submissions with script tags
- Multiple failed XSS attempts in request logs
- Suspicious content authoring activity
Network Indicators:
- HTTP requests containing script payloads in form parameters
- Unusual outbound connections from AEM to external domains
SIEM Query:
source="aem-access.log" AND ("<script>" OR "javascript:" OR "onload=" OR "onerror=")
