CVE-2025-64881

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 Adobe Experience Manager versions 6.5.23 and earlier.

💻 Affected Systems

Products:
  • Adobe Experience Manager
Versions: 6.5.23 and earlier
Operating Systems: All
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, or defacement of web pages through injected content.

🟢

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: 6.5.24 or later

Vendor Advisory: https://helpx.adobe.com/security/products/experience-manager/apsb25-115.html

Restart Required: Yes

Instructions:

1. Download Adobe Experience Manager 6.5.24 or later from Adobe's official distribution. 2. Follow Adobe's upgrade documentation for your deployment type (on-premise or cloud). 3. Restart the AEM instance after applying the update.

🔧 Temporary Workarounds

Implement Content Security Policy (CSP)

all

Add CSP headers to restrict script execution sources and mitigate XSS impact.

Add 'Content-Security-Policy' header with appropriate directives in web server or application configuration.

Input Validation and Output Encoding

all

Implement server-side validation and proper output encoding for all user inputs in form fields.

Configure AEM to use OWASP Java Encoder or similar libraries for output encoding.

🧯 If You Can't Patch

  • Restrict low-privileged user access to vulnerable form fields and components.
  • Implement web application firewall (WAF) rules to block XSS payloads in form submissions.

🔍 How to Verify

Check if Vulnerable:

Check Adobe Experience Manager version via AEM Web Console (/system/console) or by examining the CRX package manager.

Check Version:

curl -k https://<aem-host>:<port>/system/console/status-productinfo 2>/dev/null | grep 'Adobe Experience Manager'

Verify Fix Applied:

Confirm version is 6.5.24 or later and test form fields with XSS payloads to ensure they are properly sanitized.

📡 Detection & Monitoring

Log Indicators:

  • Unusual form submissions with script tags or JavaScript payloads in request logs.
  • Multiple failed login attempts followed by form submissions from same IP.

Network Indicators:

  • HTTP requests containing <script> tags or JavaScript functions in POST data to AEM form endpoints.

SIEM Query:

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