CVE-2025-46943
📋 TL;DR
Adobe Experience Manager versions 6.5.22 and earlier contain a stored XSS vulnerability where low-privileged attackers can inject malicious scripts into form fields. When users visit pages with these compromised fields, their browsers execute the attacker's JavaScript. 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 session cookies, redirect users to malicious sites, perform actions on behalf of authenticated users, or deploy additional malware payloads.
Likely Case
Session hijacking, credential theft, defacement of web pages, or limited data exfiltration from user browsers.
If Mitigated
Minimal impact with proper input validation, output encoding, and Content Security Policy (CSP) headers in place.
🎯 Exploit Status
Exploitation requires low-privileged access to vulnerable form fields. Attackers need to understand AEM's form structure but no advanced technical skills are required.
🛠️ 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's distribution portal. 2. Backup current instance and content. 3. Apply the update following Adobe's upgrade documentation. 4. Restart the AEM instance. 5. Verify the update was successful.
🔧 Temporary Workarounds
Implement Content Security Policy
allAdd CSP headers to restrict script execution sources and prevent XSS payloads from running.
Add 'Content-Security-Policy' header with appropriate directives to web server configuration
Input Validation Filter
allImplement server-side input validation for all form fields to reject malicious scripts.
Configure AEM's XSS protection filters or implement custom servlet filters
🧯 If You Can't Patch
- Implement strict Content Security Policy headers with script-src directives
- Apply output encoding to all user-controlled data displayed in web pages
🔍 How to Verify
Check if Vulnerable:
Check AEM version via CRXDE Lite or OSGi console. If version is 6.5.22 or earlier, the system is vulnerable.Check Version:
Check via AEM's welcome page or use: curl -u admin:password http://localhost:4502/system/console/status-productinfoVerify Fix Applied:
Verify AEM 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 content creation by low-privileged users
Network Indicators:
- HTTP requests containing script injection patterns
- Unexpected external script loads from AEM pages
SIEM Query:
source="aem_access.log" AND ("<script" OR "javascript:" OR "onload=" OR "onerror=")
