CVE-2025-64793
📋 TL;DR
Adobe Experience Manager versions 6.5.23 and earlier contain a stored XSS vulnerability where low-privileged attackers can inject malicious scripts into form fields. When users visit pages containing the compromised fields, their browsers execute the attacker's JavaScript. This affects organizations using vulnerable AEM instances for content management.
💻 Affected Systems
- Adobe Experience Manager
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal administrator session cookies, perform actions as authenticated users, deface websites, or redirect users to malicious sites, potentially leading to full system compromise if combined with other vulnerabilities.
Likely Case
Low-privileged users inject malicious scripts that execute in other users' browsers, potentially stealing session tokens, performing unauthorized actions, or capturing sensitive data entered in forms.
If Mitigated
With proper input validation and output encoding, malicious scripts would be neutralized before execution, preventing successful exploitation.
🎯 Exploit Status
Exploitation requires authenticated low-privileged access. The vulnerability is in form fields where user input isn't properly sanitized.
🛠️ 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 AEM 6.5.24 or later from Adobe's distribution portal. 2. Apply the service pack following Adobe's upgrade documentation. 3. Restart the AEM instance. 4. Verify the update was successful.
🔧 Temporary Workarounds
Input Validation Filter
allImplement custom servlet filters to sanitize user input in form fields before processing.
Implement Java servlet filter with input sanitization logic
Content Security Policy
allDeploy strict CSP headers to restrict script execution sources.
Add 'Content-Security-Policy' header with script-src directives
🧯 If You Can't Patch
- Restrict low-privileged user access to content authoring 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. If version is 6.5.23 or earlier, the system is vulnerable.Check Version:
curl -u admin:password http://localhost:4502/system/console/status-productinfo | grep 'Adobe Experience Manager'Verify Fix Applied:
After patching, verify version is 6.5.24 or later and test form fields with XSS payloads to ensure they're properly sanitized.📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to form submission endpoints with script tags
- 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 "onerror=" OR "onload=")
