How CVE-2025-46845 Works
Adobe Experience Manager (AEM) versions 6.5.22 and earlier fail to properly sanitize user-supplied input in certain form fields, allowing attackers to inject malicious JavaScript. When a victim accesses a compromised page, the script executes in their browser, potentially leading to session hijacking, data theft, or unauthorized actions. The vulnerability arises due to insufficient input validation in the WCM (Web Content Management) component, where crafted payloads bypass existing filters.
DailyCVE Form
Platform: Adobe Experience Manager
Version: ≤ 6.5.22
Vulnerability: Stored XSS
Severity: Critical
Date: 06/13/2025
Prediction: Patch expected by 07/15/2025
What Undercode Say:
Exploitation Analysis
- Payload Injection: Attackers submit malicious JavaScript via form fields (e.g.,
"><script>alert(document.cookie)</script>). - Persistence: The payload is stored in the AEM repository and rendered unsanitized.
- Execution: Victims trigger the script upon page load.
Protection Measures
1. Input Sanitization:
// Example OWASP Java Sanitizer import org.owasp.html.PolicyFactory; import org.owasp.html.Sanitizers; PolicyFactory sanitizer = Sanitizers.FORMATTING.and(Sanitizers.LINKS); String safeInput = sanitizer.sanitize(userInput);
2. Content Security Policy (CSP):
Content-Security-Policy: default-src 'self'; script-src 'unsafe-inline' 'unsafe-eval'
3. AEM-Specific Fix:
<!-- Disable risky components in /apps/system/config -->
<jcr:root xmlns:sling="http://sling.apache.org/jcr/sling/1.0"
xmlns:jcr="http://www.jcp.org/jcr/1.0"
jcr:primaryType="sling:OsgiConfig"
htmlLibraryManager.disabled="{Boolean}true"/>
Detection Commands
1. Repository Query for Malicious Nodes:
SELECT FROM [nt:base] WHERE CONTAINS(, '<script>')
2. Log Analysis:
grep -r "script%3E" /var/log/aem/error.log
Mitigation Steps
1. Immediate Workaround:
Disable affected components via curl curl -u admin:admin -F "enabled=false" http://localhost:4502/system/console/components/com.adobe.cq.wcm.core.components.forms.FormContainer
2. Patch Verification:
aem-6.5.23/bin/quickstart --version
