CVE-2024-52825
📋 TL;DR
Adobe Experience Manager versions 6.5.21 and earlier contain a stored Cross-Site Scripting (XSS) vulnerability that allows attackers to inject malicious JavaScript into form fields. When users visit pages containing these compromised fields, their browsers execute the attacker's code. This affects organizations using vulnerable Adobe Experience Manager instances.
💻 Affected Systems
- Adobe Experience Manager
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal session cookies, redirect users to malicious sites, perform actions on behalf of authenticated users, or install malware through drive-by downloads.
Likely Case
Session hijacking, credential theft, or defacement of web pages through injected content.
If Mitigated
Limited impact if proper input validation and output encoding are implemented, though the vulnerability still exists.
🎯 Exploit Status
Exploitation requires the attacker to have access to submit data to vulnerable form fields, which typically requires some level of access or social engineering.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 6.5.22 or later
Vendor Advisory: https://helpx.adobe.com/security/products/experience-manager/apsb24-69.html

Content Security Policy (CSP)
allImplement a strict Content Security Policy header to restrict script execution sources.
🧯 If You Can't Patch
- Implement Web Application Firewall (WAF) rules to block XSS payloads
- Restrict access to vulnerable forms to trusted users only
🔍 How to Verify
Check if Vulnerable:
Check the AEM version via the AEM Welcome page or OSGi console. If version is 6.5.21 or earlier, the system is vulnerable.Check Version:
curl -k https://<aem-host>:<port>/system/console/status-productinfo | grep 'Adobe Experience Manager'Verify Fix Applied:
After patching, verify the version is 6.5.22 or later and test form fields with XSS payloads to ensure they are properly sanitized.📡 Detection & Monitoring
