CVE-2025-46978

5.4 MEDIUM

📋 TL;DR

Adobe Experience Manager versions 6.5.22 and earlier contain a stored XSS vulnerability where low-privileged attackers can inject malicious scripts into form fields. When victims browse pages containing these compromised fields, their browsers execute the attacker's JavaScript. This affects organizations using vulnerable AEM instances for content management.

💻 Affected Systems

Products:
  • Adobe Experience Manager
Versions: 6.5.22 and earlier
Operating Systems: All supported platforms
Default Config Vulnerable: ⚠️ Yes
Notes: Requires low-privileged attacker access to vulnerable form fields.

⚠️ Risk & Real-World Impact

🔴

Worst Case

Attackers could steal session cookies, redirect users to malicious sites, perform actions on behalf of authenticated users, or deploy additional malware payloads.

🟠

Likely Case

Session hijacking, credential theft, or defacement of web content through script injection.

🟢

If Mitigated

Limited impact with proper input validation and output encoding controls 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

🔧 Temporary Workarounds

Input Validation Filter

all

Implement custom servlet filters to sanitize form field inputs before processing.

Custom Java servlet filter implementation required

Content Security Policy

all

Implement strict CSP headers to limit script execution sources.

Add 'Content-Security-Policy' header configuration to web server

🧯 If You Can't Patch

  • Restrict low-privileged user access to content editing interfaces
  • Implement web application firewall rules to block XSS payload patterns

🔍 How to Verify

Check if Vulnerable:

Check AEM version via CRXDE Lite or system console. Versions 6.5.22 or earlier are vulnerable.

Check Version:

curl -u admin:password http://localhost:4502/system/console/status-productinfo

Verify Fix Applied:

Verify AEM version is 6.5.23 or later and test form fields with XSS payloads.

📡 Detection & Monitoring

Log Indicators:

  • Unusual content modifications by low-privileged users
  • Script tags or JavaScript in form submission logs

Network Indicators:

  • HTTP requests containing script injection patterns to form endpoints

SIEM Query:

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