CVE-2025-47057
📋 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 containing 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.
Likely Case
Attackers with low privileges could elevate their access, steal user session data, or manipulate content displayed to other users.
If Mitigated
With proper input validation and output encoding, the risk is limited to potential data integrity issues in specific form fields.
🎯 Exploit Status
Requires authenticated low-privileged access. Exploitation involves injecting scripts 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's distribution portal. 2. Apply the service pack following Adobe's upgrade documentation. 3. Restart all AEM instances. 4. Verify the update was successful.
🔧 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 limit script execution sources.
Add 'Content-Security-Policy: script-src 'self'' to HTTP response headers
🧯 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 6.5.22 or earlier, system is vulnerable.Check Version:
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 confirm sanitization.📡 Detection & Monitoring
Log Indicators:
- Unusual form submissions with script tags
- Multiple failed XSS attempts in request logs
- Suspicious user agent strings in form submissions
Network Indicators:
- HTTP requests containing script injection patterns to form endpoints
- Unusual outbound connections from AEM instances
SIEM Query:
source="aem_logs" AND ("<script>" OR "javascript:" OR "onerror=" OR "onload=")
