CVE-2025-64791

5.4 MEDIUM

📋 TL;DR

This 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, potentially leading to session hijacking, data theft, or unauthorized actions. Organizations using Adobe Experience Manager versions 6.5.23 and earlier are affected.

💻 Affected Systems

Products:
  • Adobe Experience Manager
Versions: 6.5.23 and earlier
Operating Systems: All supported platforms
Default Config Vulnerable: ⚠️ Yes
Notes: Requires low-privileged attacker access to vulnerable form fields. All deployment types (on-premise, cloud) are affected.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Attackers could steal administrator credentials, perform account takeovers, deface websites, or redirect users to malicious sites, potentially leading to complete system compromise.

🟠

Likely Case

Attackers with low privileges could steal session cookies, perform actions as authenticated users, or capture sensitive data entered by users.

🟢

If Mitigated

With proper input validation and output encoding, the vulnerability would be prevented, though the underlying code flaw remains.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

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

Exploitation requires low-privileged access to vulnerable form fields. The vulnerability is stored/persistent, making it more dangerous than reflected XSS.

🛠️ 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 specific deployment type. 3. Apply the update to all affected instances. 4. Restart the AEM service. 5. Verify the update was successful.

🔧 Temporary Workarounds

Input Validation Filter

all

Implement server-side input validation to sanitize user input in form fields

Configure AEM's XSS Protection API or implement custom servlet filters

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
  • Restrict low-privileged user access to content editing capabilities

🔍 How to Verify

Check if Vulnerable:

Check AEM version via OSGi console or CRXDE. If version is 6.5.23 or earlier, the system is vulnerable.

Check Version:

curl -u admin:admin http://localhost:4502/system/console/status-productinfo | grep 'Adobe Experience Manager'

Verify Fix Applied:

After patching, verify version is 6.5.24 or later and test form fields with XSS payloads to ensure they're properly sanitized.

📡 Detection & Monitoring

Log Indicators:

  • Unusual content modifications in form fields
  • Suspicious script tags in content submissions
  • Multiple failed XSS attempts

Network Indicators:

  • Malicious script payloads in HTTP POST requests
  • Unexpected external script loads from AEM pages

SIEM Query:

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