CVE-2025-46945
📋 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
- 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, or defacement of web pages through injected content.
If Mitigated
Limited impact if proper input validation and output encoding are implemented, though risk remains for unpatched systems.
🎯 Exploit Status
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 official distribution. 2. Follow Adobe's upgrade documentation for your deployment type (on-premise or cloud). 3. Apply the update and restart the AEM service.
🔧 Temporary Workarounds
Input Validation and Output Encoding
allImplement strict input validation and output encoding for all form fields to prevent script injection.
Content Security Policy (CSP)
allDeploy a strict Content Security Policy header to mitigate XSS impact by restricting script execution sources.
🧯 If You Can't Patch
- Restrict low-privileged user access to form fields and implement web application firewall (WAF) rules to block XSS payloads.
- Monitor application logs for suspicious input patterns and implement regular security audits of form handling code.
🔍 How to Verify
Check if Vulnerable:
Check Adobe Experience Manager version via AEM Web Console (/system/console) or by examining the CRX package manager for version information.Check Version:
curl -k https://<aem-host>:<port>/system/console/status-productinfo 2>/dev/null | grep 'Adobe Experience Manager'Verify Fix Applied:
Verify the version is 6.5.23 or later and test form fields with XSS payloads to ensure they are properly sanitized.📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to form endpoints with script tags or JavaScript payloads in parameters.
- Error logs showing input validation failures for form submissions.
Network Indicators:
- HTTP requests containing <script> tags or JavaScript functions in form data.
- Unexpected redirects or outbound connections from user browsers after visiting AEM pages.
