How CVE-2025-46862 Works
Adobe Experience Manager (AEM) 6.5.22 and earlier fails to properly sanitize user-supplied input in form fields, allowing attackers to inject malicious JavaScript payloads. When a victim accesses a compromised page, the script executes in their browser session, 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 HTML/JS persists in the content repository.
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 into vulnerable form fields (e.g., text components, dialog fields).
2. Persistence: Malicious scripts save to AEM’s JCR repository.
3. Execution: Victims trigger payloads when rendering the page.
Detection
grep -r "unsafeHTML" /path/to/aem/components Find unsafe rendering methods
Mitigation
1. Temporary Fix:
// Use XSS filters in Sightly/HTL
${fn:escapeXml(userInput)}
2. Apache Sling XSS Protection:
<dependency> <groupId>org.apache.sling</groupId> <artifactId>org.apache.sling.xss</artifactId> <version>2.4.0</version> </dependency>
3. Disable Risky Components:
curl -u admin:password -X POST -F "enabled=false" http://aem-host:4502/system/console/components/com.adobe.granite.xssprotection
Analytics
- Attack Surface: WCM forms, dialogs, custom components.
- CVSS 4.0: 9.6 (AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H).
