CVE-2025-47029

5.4 MEDIUM

📋 TL;DR

This stored XSS vulnerability in Adobe Experience Manager allows low-privileged attackers to inject malicious JavaScript into form fields. When victims browse pages containing the injected scripts, their browsers execute the malicious code. Organizations using AEM versions 6.5.22 and earlier are affected.

💻 Affected Systems

Products:
  • Adobe Experience Manager
Versions: 6.5.22 and earlier
Operating Systems: All supported platforms
Default Config Vulnerable: ⚠️ Yes
Notes: Requires low-privileged attacker access to vulnerable form fields. AEM as a Cloud Service is not affected.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Attackers could steal session cookies, perform actions as authenticated users, redirect to malicious sites, or install malware on victim systems.

🟠

Likely Case

Session hijacking, credential theft, or defacement of AEM content pages through injected scripts.

🟢

If Mitigated

Limited impact with proper input validation, output encoding, and Content Security Policy (CSP) headers in place.

🌐 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 typically has lower complexity than reflected XSS.

🛠️ 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 AEM instances. 4. Verify successful upgrade.

🔧 Temporary Workarounds

Implement Content Security Policy

all

Add CSP headers to restrict script execution sources

Add 'Content-Security-Policy' header to web server configuration

Input Validation Filter

all

Implement server-side input validation for form fields

Configure AEM filters to sanitize user input

🧯 If You Can't Patch

  • Restrict low-privileged user access to content editing capabilities
  • Implement web application firewall (WAF) rules to block XSS payloads

🔍 How to Verify

Check if Vulnerable:

Check AEM version via CRXDE Lite or OSGi console. Versions 6.5.22 and earlier are vulnerable.

Check Version:

curl -u admin:password http://localhost:4502/system/console/status-productinfo

Verify Fix Applied:

Verify AEM version is 6.5.23 or later and test form fields for XSS injection.

📡 Detection & Monitoring

Log Indicators:

  • Unusual content modifications
  • Suspicious script tags in content nodes
  • Multiple failed XSS attempts

Network Indicators:

  • Malicious script payloads in HTTP requests
  • Unexpected external script loads

SIEM Query:

source="aem.log" AND ("script" OR "javascript" OR "onload" OR "onerror")
