CVE-2025-46888
📋 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 administrator session cookies, perform actions as authenticated users, deface websites, or redirect users to malicious sites, potentially leading to full system compromise.
Likely Case
Low-privileged users inject malicious scripts that execute in other users' browsers, enabling session hijacking, credential theft, or limited content manipulation.
If Mitigated
With proper input validation and output encoding, the vulnerability would be prevented, though the underlying code flaw remains.
🎯 Exploit Status
Exploitation requires authenticated low-privileged access; stored XSS typically has straightforward exploitation patterns.
🛠️ 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. Apply the service pack following Adobe's upgrade documentation. 3. Restart all AEM instances. 4. Verify the update completed successfully.
🔧 Temporary Workarounds
Implement Input Validation
allAdd server-side validation to sanitize all user input in form fields before processing.
Enable Content Security Policy
allImplement CSP headers to restrict script execution sources and mitigate XSS impact.
🧯 If You Can't Patch
- Restrict low-privileged user access to vulnerable form fields and components.
- Implement web application firewall rules to detect and block XSS payloads.
🔍 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-productinfoVerify Fix Applied:
After patching, confirm version is 6.5.23 or later and test form fields with basic XSS payloads to ensure they're sanitized.📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to form endpoints with script tags
- Multiple failed validation attempts on form submissions
Network Indicators:
- HTTP requests containing script injection patterns to AEM endpoints
SIEM Query:
source="aem_access.log" AND ("<script>" OR "javascript:" OR "onerror=" OR "onload=")
