CVE-2025-64869
📋 TL;DR
This stored Cross-Site Scripting (XSS) vulnerability in Adobe Experience Manager allows low-privileged attackers to inject malicious JavaScript into vulnerable form fields. When users visit pages containing these compromised fields, their browsers execute the attacker's code, potentially leading to session hijacking or data theft. Organizations running Adobe Experience Manager versions 6.5.23 and earlier are affected.
💻 Affected Systems
- Adobe Experience Manager
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal administrator credentials, hijack user sessions, deface websites, or redirect users to malicious sites, potentially leading to complete system compromise.
Likely Case
Attackers with low privileges steal session cookies or user credentials, perform actions on behalf of authenticated users, or conduct phishing attacks.
If Mitigated
With proper input validation and output encoding, the vulnerability would be prevented, though the underlying code flaw remains until patched.
🎯 Exploit Status
Exploitation requires low-privileged access to vulnerable form fields; stored XSS typically has low complexity once vulnerable fields are identified.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 6.5.24 or later
Vendor Advisory: https://helpx.adobe.com/security/products/experience-manager/apsb25-115.html
Restart Required: Yes
Instructions:
1. Download Adobe Experience Manager 6.5.24 or later from Adobe's official distribution channels. 2. Apply the update following Adobe's upgrade documentation. 3. Restart the AEM service to apply changes. 4. Verify the update was successful by checking the version.
🔧 Temporary Workarounds
Input Validation and Output Encoding
allImplement strict input validation and output encoding for all form fields to prevent XSS payloads from being stored and executed.
Content Security Policy (CSP)
allDeploy a strict Content Security Policy to mitigate the impact of successful XSS attacks by restricting script execution sources.
🧯 If You Can't Patch
- Implement web application firewall (WAF) rules to block XSS payload patterns in form submissions.
- Restrict low-privileged user access to form editing capabilities and implement additional authentication for sensitive operations.
🔍 How to Verify
Check if Vulnerable:
Check Adobe Experience Manager version via AEM Web Console (/system/console) or by examining the CRX package manager; versions 6.5.23 or earlier are vulnerable.Check Version:
curl -k https://<aem-host>:<port>/system/console/status-productinfo 2>/dev/null | grep 'Adobe Experience Manager'Verify Fix Applied:
After patching, verify the version is 6.5.24 or later and test form fields for XSS by attempting to inject basic script payloads (in a controlled manner).📡 Detection & Monitoring
Log Indicators:
- Unusual form submissions containing script tags or JavaScript code
- Multiple failed login attempts following form submissions
- Unexpected changes to stored content in CRX repository
Network Indicators:
- HTTP requests containing script tags or JavaScript in form parameters
- Outbound connections to suspicious domains following form submissions
