CVE-2025-46865
📋 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. This affects Adobe Experience Manager versions 6.5.22 and earlier.
💻 Affected Systems
- Adobe Experience Manager
📦 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 install malware on victim systems.
Likely Case
Session hijacking, credential theft, defacement of web pages, or data exfiltration from user browsers.
If Mitigated
Limited impact with proper input validation, output encoding, and Content Security Policy (CSP) headers in place.
🎯 Exploit Status
Exploitation requires authenticated low-privileged access. Stored XSS typically has low complexity once vulnerable fields are identified.
🛠️ 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 official distribution. 2. Follow Adobe's upgrade documentation for your deployment type (on-premise or cloud). 3. Apply the update to all affected instances. 4. Restart the AEM service. 5. Verify the update was successful.
🔧 Temporary Workarounds
Implement Content Security Policy
allAdd CSP headers to restrict script execution sources and prevent inline script execution.
Add 'Content-Security-Policy: default-src 'self'; script-src 'self'' to web server configuration
Input Validation and Output Encoding
allImplement server-side validation and proper output encoding for all user inputs in form fields.
Implement input validation using Adobe Experience Manager's XSS API: org.apache.sling.xss.XSSAPI
🧯 If You Can't Patch
- Restrict access to vulnerable form fields using AEM permissions and access controls.
- Implement web application firewall (WAF) rules to block XSS payloads in form submissions.
🔍 How to Verify
Check if Vulnerable:
Check Adobe Experience Manager version via AEM Web Console (/system/console/status-productinfo) or CRXDE Lite. If version is 6.5.22 or earlier, system is vulnerable.Check Version:
curl -k https://<aem-host>:<port>/system/console/status-productinfo | grep 'Adobe Experience Manager'Verify Fix Applied:
Verify version is 6.5.23 or later via AEM Web Console. Test form fields with safe XSS payloads to confirm proper sanitization.📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to form submission endpoints with script tags or JavaScript payloads
- Multiple failed login attempts followed by form submissions
Network Indicators:
- HTTP requests containing <script> tags or JavaScript in form parameters
- Unusual outbound connections from AEM server after form submissions
SIEM Query:
source="aem_access.log" AND ("<script>" OR "javascript:" OR "onload=" OR "onerror=")
