CVE-2025-46953
📋 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, potentially leading to session hijacking, data theft, or unauthorized actions. Organizations using Adobe Experience Manager versions 6.5.22 and earlier are affected.
💻 Affected Systems
- Adobe Experience Manager
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal administrator sessions, compromise user accounts, exfiltrate sensitive data, or perform unauthorized administrative actions within the AEM environment.
Likely Case
Attackers with low privileges could hijack user sessions, steal authentication cookies, redirect users to malicious sites, or deface content pages.
If Mitigated
With proper input validation and output encoding controls, the risk is reduced to minimal, though the vulnerability still exists in the codebase.
🎯 Exploit Status
Exploitation requires low-privileged access to vulnerable form fields. The vulnerability is stored XSS, meaning malicious payloads persist until removed.
🛠️ 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 channels. 2. Backup your current AEM instance and all custom configurations. 3. Apply the update following Adobe's official upgrade procedures. 4. Restart the AEM service to apply changes. 5. Verify the update was successful by checking the version.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation and output encoding for all form fields to prevent XSS payloads from being stored and executed.
Content Security Policy (CSP)
allImplement a strict Content Security Policy header to restrict script execution sources and prevent inline script execution.
🧯 If You Can't Patch
- Implement web application firewall (WAF) rules to detect and block XSS payloads in form submissions.
- Restrict low-privileged user access to form editing capabilities and implement additional authentication for sensitive operations.
🔍 How to Verify
Check if Vulnerable:
Check Adobe Experience Manager version via AEM Web Console (/system/console) or by examining the CRX package manager. Versions 6.5.22 or earlier are vulnerable.Check Version:
curl -s http://localhost:4502/system/console/status-productinfo | grep 'Adobe Experience Manager'Verify Fix Applied:
After patching, verify the version shows 6.5.23 or later. Test form fields with safe XSS payloads to ensure they are properly sanitized.📡 Detection & Monitoring
Log Indicators:
- Unusual form submissions containing script tags or JavaScript code
- Multiple failed login attempts followed by form submissions
- Administrative actions from unexpected user accounts
Network Indicators:
- HTTP requests containing script tags or JavaScript in form parameters
- Outbound connections to suspicious domains following form submissions
