📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise leading to data theft, ransomware deployment, lateral movement across networks, and persistent backdoor installation.
Likely Case
Initial foothold for attackers to deploy malware, steal sensitive data, and establish persistence in the environment.
If Mitigated
Limited impact through network segmentation and strict access controls, but still poses significant risk due to pre-authentication nature.
🎯 Exploit Status
CISA has added this to their Known Exploited Vulnerabilities catalog, confirming active exploitation. The vulnerability is pre-authentication and trivial to exploit.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 6.5.24 or later
Vendor Advisory: https://helpx.adobe.com/security/products/aem-forms/apsb25-82.html
Restart Required: Yes

🔧 Temporary Workarounds
Disable Struts devMode
allDisable the Struts development mode which is the root cause of the vulnerability
Edit struts.xml configuration file and set <constant name="struts.devMode" value="false" />
Network Segmentation
allRestrict network access to AEM Forms instances
Configure firewall rules to limit access to AEM Forms ports (typically 4502, 4503) to trusted IPs only
🧯 If You Can't Patch
- Immediately isolate affected systems from internet access and restrict internal network access
- Implement web application firewall (WAF) rules to block suspicious Struts-related requests
🔍 How to Verify
Check if Vulnerable:
Check AEM Forms version via AEM Web Console (/system/console/bundles) or by examining the installed service pack versionCheck Version:
curl -k https://<aem-host>:<port>/system/console/bundles | grep 'Adobe Experience Manager'Verify Fix Applied:
Verify version is 6.5.24 or later and confirm struts.devMode is set to false in configuration📡 Detection & Monitoring
