CVE-2025-64841

5.4 MEDIUM

📋 TL;DR

Adobe Experience Manager versions 6.5.23 and earlier contain a stored Cross-Site Scripting vulnerability that allows low-privileged attackers to inject malicious scripts into form fields. When users visit pages containing these compromised fields, their browsers execute the attacker's JavaScript, potentially leading to session hijacking or data theft.

💻 Affected Systems

Products:
  • Adobe Experience Manager
Versions: 6.5.23 and earlier
Operating Systems: All platforms running AEM
Default Config Vulnerable: ⚠️ Yes
Notes: Requires attacker to have at least contributor-level permissions to access vulnerable form fields.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Attacker steals administrator session cookies, gains full system control, and exfiltrates sensitive data or deploys ransomware.

🟠

Likely Case

Low-privileged attacker steals user session tokens, escalates privileges, and accesses unauthorized data.

🟢

If Mitigated

Attack limited to same-origin context with proper CSP headers and input validation in place.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

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

Exploitation requires authenticated access but uses common XSS techniques that are well-documented.

🛠️ 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 AEM 6.5.24+ from Adobe Distribution portal. 2. Backup current instance. 3. Apply Service Pack using Package Manager. 4. Restart AEM instance. 5. Verify successful update.

🔧 Temporary Workarounds

Input Validation Filter

all

Implement custom servlet filter to sanitize form field inputs

Deploy custom XSS filter via OSGi component or servlet filter

Content Security Policy

all

Implement strict CSP headers to block inline script execution

Configure Apache/Dispatcher with: Header set Content-Security-Policy "default-src 'self'; script-src 'self'"
Add CSP via AEM OSGi configuration

🧯 If You Can't Patch

  • Restrict form field permissions to trusted users only
  • Implement web application firewall with XSS protection rules

🔍 How to Verify

Check if Vulnerable:

Check AEM version via CRXDE Lite or System Console. If version is 6.5.23 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 6.5.24+ and test form fields with XSS payloads like <script>alert('test')</script>

📡 Detection & Monitoring

Log Indicators:

  • Unusual POST requests to form submission endpoints
  • Requests containing script tags or JavaScript in form parameters
  • Multiple failed login attempts followed by form submissions

Network Indicators:

  • Outbound connections to suspicious domains from AEM server
  • Unusual traffic patterns to form handler endpoints

SIEM Query:

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