CVE-2025-46965

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 6.5.22 and earlier.

💻 Affected Systems

Products:
  • Adobe Experience Manager
Versions: 6.5.22 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 deploy ransomware-like payloads within the application context.

🟠

Likely Case

Session hijacking, credential theft, or defacement of application 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: 6.5.23 or later

Vendor Advisory: https://helpx.adobe.com/security/products/experience-manager/apsb25-48.html

Restart Required: Yes

Instructions:

1. Download Adobe Experience Manager 6.5.23 or later from Adobe's distribution portal. 2. Follow Adobe's upgrade documentation for your deployment type (AEM as a Cloud Service, AMS, or on-premise). 3. Apply the update and restart all AEM instances.

🔧 Temporary Workarounds

Implement Content Security Policy

all

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

Add 'Content-Security-Policy' header to web server configuration with appropriate directives.

Input Validation Filter

all

Deploy custom servlet filter to sanitize form field inputs before processing.

Implement Java servlet filter using OWASP Java Encoder or similar library to sanitize user inputs.

🧯 If You Can't Patch

  • Restrict low-privileged user access to form creation/modification capabilities.
  • Implement web application firewall (WAF) rules to detect and block XSS payloads.

🔍 How to Verify

Check if Vulnerable:

Check AEM version via OSGi console (http://[host]:[port]/system/console/bundles) or CRXDE Lite package manager.

Check Version:

curl -s http://localhost:4502/system/console/bundles | grep 'Adobe Experience Manager'

Verify Fix Applied:

Confirm version is 6.5.23 or later and test form fields with XSS payloads to ensure sanitization.

📡 Detection & Monitoring

Log Indicators:

  • Unusual form submissions with script tags or JavaScript payloads in request parameters.
  • Multiple failed XSS attempts from same user/IP.

Network Indicators:

  • HTTP requests containing <script>, javascript:, or encoded XSS payloads in POST data.

SIEM Query:

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