CVE-2025-46914
📋 TL;DR
Adobe Experience Manager versions 6.5.22 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, potentially leading to complete system compromise.
Likely Case
Low-privileged users inject malicious scripts that execute when other users view affected pages, potentially stealing session tokens or performing unauthorized actions.
If Mitigated
With proper input validation and output encoding, malicious scripts are neutralized before execution, preventing successful exploitation.
🎯 Exploit Status
Requires low-privileged authenticated access. Exploitation involves injecting JavaScript into vulnerable form fields.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 6.5.23 or later
Vendor Advisory: https://helpx.adobe.com/security/products/experience-manager/apsb25-48.html
Restart Required: Yes
Instructions:
1. Download AEM 6.5.23 or later from Adobe distribution. 2. Backup current instance. 3. Apply the update following Adobe's upgrade documentation. 4. Restart the AEM instance. 5. Verify the update was successful.
🔧 Temporary Workarounds
Input Validation Filter
allImplement server-side input validation to sanitize form field inputs before processing.
Implement custom servlet filter or use AEM's XSS protection API
Content Security Policy
allDeploy strict Content Security Policy headers to limit script execution.
Add 'Content-Security-Policy: default-src 'self'; script-src 'self'' to HTTP headers
🧯 If You Can't Patch
- Restrict low-privileged user access to form creation/modification 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 6.5.22 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 6.5.23 or later and test form fields with XSS payloads to ensure they're properly sanitized.📡 Detection & Monitoring
Log Indicators:
- Unusual form submissions with script tags
- Multiple failed XSS attempts in request logs
- Suspicious user input patterns in form fields
Network Indicators:
- HTTP requests containing script injection patterns
- Unusual outbound connections from AEM to external domains
SIEM Query:
source="aem_access.log" AND ("<script>" OR "javascript:" OR "onload=" OR "onerror=")
