CVE-2025-47077
📋 TL;DR
Adobe Experience Manager versions 6.5.22 and earlier contain a stored Cross-Site Scripting (XSS) vulnerability that allows low-privileged attackers to inject malicious scripts into form fields. When victims browse pages containing these compromised fields, their browsers execute the attacker's JavaScript, potentially leading to session hijacking or data theft.
💻 Affected Systems
- Adobe Experience Manager
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal administrator sessions, compromise user accounts, deface websites, or redirect users to malicious sites, potentially leading to full system compromise if combined with other vulnerabilities.
Likely Case
Low-privileged attackers inject malicious scripts to steal session cookies or credentials from users who view the compromised pages, enabling account takeover or data exfiltration.
If Mitigated
With proper input validation and output encoding, the vulnerability would be prevented, though residual risk remains if other XSS vectors exist.
🎯 Exploit Status
Exploitation requires low-privileged access to inject scripts into vulnerable form fields. No public exploit code is currently available.
🛠️ 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. Download Adobe Experience Manager 6.5.23 or later from Adobe's official distribution. 2. Follow Adobe's upgrade documentation to apply the patch. 3. Restart all AEM instances after patching. 4. Verify the patch is applied correctly.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation and output encoding for all user-controllable form fields to prevent script injection.
Configure AEM's XSS protection filters and validation rules according to Adobe security guidelines.
Content Security Policy (CSP)
allImplement a strict Content Security Policy header to mitigate the impact of successful XSS attacks by restricting script execution.
Add 'Content-Security-Policy' header with appropriate directives to web server configuration.
🧯 If You Can't Patch
- Implement web application firewall (WAF) rules to block XSS payloads in form submissions.
- Restrict low-privileged user access to form editing capabilities and implement additional monitoring for suspicious activities.
🔍 How to Verify
Check if Vulnerable:
Check AEM version via the Welcome screen or CRXDE Lite. If version is 6.5.22 or earlier, the system is vulnerable.Check Version:
Check the AEM Welcome page or use CRXDE Lite to view system information.Verify Fix Applied:
Verify the AEM version is 6.5.23 or later and test form fields for XSS vulnerabilities using security testing tools.📡 Detection & Monitoring
Log Indicators:
- Unusual form submissions with script tags or JavaScript code in request parameters
- Multiple failed XSS attempts in web server logs
Network Indicators:
- HTTP requests containing suspicious script payloads in form fields
- Unexpected outbound connections from user browsers after visiting specific pages
