CVE-2025-46931

5.4 MEDIUM

📋 TL;DR

This stored 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 compromising user sessions or stealing sensitive data. Organizations using Adobe Experience Manager versions 6.5.22 and earlier are affected.

💻 Affected Systems

⚠️ Risk & Real-World Impact

🔴

Worst Case

Attackers could steal administrator credentials, hijack user sessions, 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 form data submitted by users.

🟢

If Mitigated

With proper input validation and output encoding, the risk is limited to potential data leakage from the specific vulnerable field.

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

Configure AEM's XSS protection filters to validate and sanitize form field inputs

Content Security Policy

all

Implement strict Content Security Policy headers to limit script execution

Add 'Content-Security-Policy: script-src 'self'' to HTTP response headers

🧯 If You Can't Patch

  • Restrict low-privileged user access to vulnerable form fields and components
  • Implement web application firewall rules to detect and block XSS payloads

🔍 How to Verify

Check if Vulnerable:

Check AEM version via AEM Web Console (/system/console/bundles) or CRXDE Lite, verify version is 6.5.22 or earlier

Check Version:

curl -k https://<aem-host>:<port>/system/console/bundles | grep 'Adobe Experience Manager'

Verify Fix Applied:

Verify AEM version is 6.5.23 or later, test form fields with XSS payloads to ensure they're properly sanitized

📡 Detection & Monitoring

Log Indicators:

  • Unusual POST requests to form endpoints with script tags or JavaScript payloads
  • Multiple failed XSS attempts in request logs

Network Indicators:

  • HTTP requests containing <script> tags or JavaScript functions in form parameters

SIEM Query:

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