CVE-2025-47035
📋 TL;DR
A stored cross-site scripting (XSS) vulnerability in Adobe Experience Manager allows low-privileged attackers to inject malicious scripts into form fields, which execute in victims' browsers when they view the affected pages. This affects versions 6.5.22 and earlier, potentially compromising user sessions or stealing data. Users of these vulnerable Adobe Experience Manager instances are at risk.
💻 Affected Systems
- Adobe Experience Manager
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal session cookies, perform actions as authenticated users, or redirect users to malicious sites, leading to full account compromise or data theft.
Likely Case
Low-privileged attackers inject scripts to hijack user sessions or deface web pages, causing limited data exposure or disruption.
If Mitigated
With input validation and output encoding, the risk is reduced to minimal, preventing script execution and limiting impact to failed attempts.
🎯 Exploit Status
Exploitation requires low-privileged access to inject scripts; no public proof-of-concept is known, but the vulnerability is straightforward to abuse.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 6.5.23 or later
Vendor Advisory: https://helpx.adobe.com/security/products/experience-manager/apsb25-48.html
Restart Required: Yes
Instructions:
1. Backup your Adobe Experience Manager instance. 2. Apply the patch by upgrading to version 6.5.23 or later as per Adobe's instructions. 3. Restart the service to apply changes. 4. Verify the fix by testing vulnerable form fields.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement server-side input validation and output encoding for all form fields to block malicious script injection.
Configure input filters in AEM to sanitize user inputs, e.g., using OWASP ESAPI libraries or custom validation rules.
Content Security Policy (CSP)
allDeploy a strict CSP to prevent execution of unauthorized scripts, reducing the impact of XSS attacks.
Add CSP headers in web server configuration, e.g., 'Content-Security-Policy: default-src 'self'; script-src 'self''.
🧯 If You Can't Patch
- Restrict access to vulnerable form fields by implementing role-based access controls to limit low-privileged user interactions.
- Monitor and audit logs for suspicious input patterns or script injection attempts to detect and respond to exploitation.
🔍 How to Verify
Check if Vulnerable:
Check the Adobe Experience Manager version via the admin console or by inspecting the installation directory; if version is 6.5.22 or earlier, it is vulnerable.Check Version:
On the AEM server, run: 'java -jar aem-quickstart.jar -version' or check the CRXDE Lite interface for version info.Verify Fix Applied:
After patching, confirm the version is 6.5.23 or later and test form fields with safe payloads to ensure scripts are not executed.📡 Detection & Monitoring
Log Indicators:
- Unusual input patterns in form submissions, such as script tags or JavaScript code in request logs.
Network Indicators:
- HTTP requests containing malicious script payloads to form endpoints.
SIEM Query:
Example: 'source="aem_logs" AND (message CONTAINS "<script>" OR message CONTAINS "javascript:")'
