CVE-2025-64817
📋 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, or redirect users to malicious sites, potentially leading to full system compromise.
Likely Case
Low-privileged users inject malicious scripts that execute when other users view affected pages, potentially stealing session data or performing unauthorized actions.
If Mitigated
With proper input validation and output encoding, malicious scripts would be neutralized before execution, preventing successful exploitation.
🎯 Exploit Status
Exploitation requires authenticated access with at least contributor permissions. Attack involves injecting scripts into 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
Instructions:
1. Download AEM 6.5.24 or later from Adobe Distribution. 2. Apply the Service Pack following Adobe's installation guide. 3. Restart AEM instances. 4. Verify successful update via AEM welcome screen.
🔧 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
allImplement strict CSP headers to prevent script execution from untrusted sources
Add 'Content-Security-Policy: default-src 'self'; script-src 'self'' to HTTP headers
🧯 If You Can't Patch
- Restrict contributor permissions to trusted users only
- Implement web application firewall rules to block XSS payloads
🔍 How to Verify
Check if Vulnerable:
Check AEM version via Welcome screen or CRXDE. Versions 6.5.23 and earlier are vulnerable.Check Version:
Navigate to AEM welcome screen or use 'curl -k https://aem-host:port/libs/granite/core/content/login.html | grep version'Verify Fix Applied:
Verify AEM version is 6.5.24 or later. Test form fields with XSS payloads to confirm sanitization.📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to form endpoints with script tags
- Multiple failed login attempts followed by form submissions
Network Indicators:
- HTTP requests containing <script> tags in form parameters
- Outbound connections to suspicious domains after form submissions
SIEM Query:
source="aem-access.log" AND ("<script>" OR "javascript:" OR "onerror=" OR "onload=")
