CVE-2025-47008

5.4 MEDIUM

📋 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 victims browse pages containing these compromised fields, their browsers execute the attacker's JavaScript. This affects organizations using vulnerable AEM instances for content management.

💻 Affected Systems

Products:
  • Adobe Experience Manager
Versions: 6.5.22 and earlier
Operating Systems: All platforms running AEM
Default Config Vulnerable: ⚠️ Yes
Notes: Affects both author and publish instances; requires attacker to have low-privileged access to inject scripts.

📦 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

Attackers with low privileges inject malicious scripts to steal session cookies or credentials from users who view compromised pages, enabling privilege escalation or data theft.

🟢

If Mitigated

With proper input validation and output encoding, malicious scripts are neutralized, preventing execution and limiting impact to failed injection attempts.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: LOW

Exploitation requires authenticated low-privileged access; stored XSS is straightforward once vulnerable fields are identified.

🛠️ 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. Backup AEM instance. 2. Download and apply AEM 6.5.23+ update from Adobe Distribution. 3. Restart AEM services. 4. Verify update via AEM console.

🔧 Temporary Workarounds

Implement Input Validation Filters

all

Add custom servlet filters to sanitize user input in form fields before processing.

Create and deploy custom Java filter implementing javax.servlet.Filter to sanitize parameters

Enable Content Security Policy

all

Configure CSP headers to restrict script execution sources.

Set HTTP header: Content-Security-Policy: script-src 'self'

🧯 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 OSGi console (http://host:port/system/console/bundles) or CRXDE; if version ≤6.5.22, vulnerable.

Check Version:

curl -s http://localhost:4502/system/console/bundles | grep 'Adobe Experience Manager'

Verify Fix Applied:

Confirm AEM version is 6.5.23+ and test form fields with XSS payloads (e.g., <script>alert('test')</script>) to ensure sanitization.

📡 Detection & Monitoring

Log Indicators:

  • Unusual POST requests to form handlers with script tags
  • Error logs showing malformed input rejection

Network Indicators:

  • HTTP traffic containing script payloads in form parameters
  • Unexpected outbound connections from AEM to external domains

SIEM Query:

source="aem_access.log" AND ("<script" OR "javascript:" OR "onerror=" OR "onload=")
