CVE-2025-47055

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. AEM instances with custom form configurations may have different exposure levels.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Attackers could steal administrator credentials, perform actions as authenticated users, deface websites, or redirect users to malicious sites.

🟠

Likely Case

Attackers with low privileges could steal session cookies, perform limited actions as other users, or modify content they shouldn't have access to.

🟢

If Mitigated

With proper input validation and output encoding, malicious scripts would be neutralized before reaching user browsers.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

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

Exploitation requires authenticated low-privileged access. Attackers need to identify and access 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 the AEM instance. 4. Verify the update was successful.

🔧 Temporary Workarounds

Input Validation Filter

all

Implement custom servlet filters to sanitize user input in form fields

Implement Java servlet filter with OWASP Java Encoder library

Content Security Policy

all

Implement strict CSP headers to limit script execution

Add 'Content-Security-Policy' header with script-src directives

🧯 If You Can't Patch

  • Implement web application firewall (WAF) rules to block XSS payloads
  • Review and restrict low-privileged user access to form editing capabilities

🔍 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 | grep 'Adobe Experience Manager'

Verify Fix Applied:

After patching, verify version is 6.5.23 or later. Test form fields with safe XSS payloads to confirm sanitization.

📡 Detection & Monitoring

Log Indicators:

  • Unusual form submissions with script tags
  • Multiple failed XSS attempts in request logs
  • Suspicious content modifications by low-privileged users

Network Indicators:

  • HTTP requests containing script injection patterns
  • Unusual outbound connections from AEM to external domains

SIEM Query:

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