CVE-2025-64790
📋 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 6.5.23 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 with proper input validation and output encoding in place, though risk remains if vulnerable fields are exposed.
🎯 Exploit Status
Exploitation requires low-privileged access to inject scripts; stored XSS typically has straightforward exploitation once vulnerable fields are identified.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 6.5.24 or later
Vendor Advisory: https://helpx.adobe.com/security/products/experience-manager/apsb25-115.html
Restart Required: Yes
Instructions:
1. Download Adobe Experience Manager 6.5.24 or later from Adobe's official distribution. 2. Follow Adobe's upgrade documentation to apply the patch. 3. Restart the AEM instance to ensure changes take effect.
🔧 Temporary Workarounds
Input Validation and Output Encoding
allImplement strict input validation and output encoding for all user-controllable form fields to prevent script injection.
Content Security Policy (CSP)
allDeploy a strict Content Security Policy to mitigate XSS impact by restricting script execution sources.
🧯 If You Can't Patch
- Restrict low-privileged user access to form fields and administrative interfaces.
- Monitor and audit user inputs in form fields for suspicious script patterns.
🔍 How to Verify
Check if Vulnerable:
Check Adobe Experience Manager version via AEM Web Console (/system/console/status-productinfo) or by reviewing installation logs.Check Version:
curl -k https://<aem-host>:<port>/system/console/status-productinfo | grep 'Adobe Experience Manager'Verify Fix Applied:
Confirm version is 6.5.24 or later and test form fields for XSS by attempting to inject benign scripts (e.g., <script>alert('test')</script>) in a controlled environment.📡 Detection & Monitoring
Log Indicators:
- Unusual script tags or JavaScript in form submissions in AEM logs
- Multiple failed login attempts followed by form field modifications
Network Indicators:
- HTTP requests containing script payloads to AEM endpoints
- Unexpected redirects or external resource loads from AEM pages
SIEM Query:
source="aem.log" AND ("<script>" OR "javascript:" OR "onerror=" OR "onload=")
