CVE-2025-47039

5.4 MEDIUM

📋 TL;DR

A stored Cross-Site Scripting (XSS) vulnerability in Adobe Experience Manager allows low-privileged attackers to inject malicious JavaScript into vulnerable form fields. When victims browse pages containing these fields, their browsers execute the attacker's scripts. This affects AEM versions 6.5.22 and earlier.

💻 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.

📦 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, defacement of web pages, or data exfiltration from user browsers.

🟢

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 to 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 AEM instances. 4. Verify the update was successful.

🔧 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

Deploy servlet filter to sanitize form inputs

Implement custom filter to validate and encode user inputs

🧯 If You Can't Patch

  • Restrict low-privileged user access to form 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 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-productinfo

Verify Fix Applied:

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

📡 Detection & Monitoring

Log Indicators:

  • Unusual form submissions with script tags
  • Requests containing JavaScript payloads in parameters

Network Indicators:

  • HTTP requests with script payloads in POST data
  • Unusual outbound connections from user browsers

SIEM Query:

source="aem-access.log" AND ("<script>" OR "javascript:" OR "onerror=" OR "onload=")
