CVE-2024-4447
📋 TL;DR
This vulnerability exposes sensitive session and user data through Direct Web Remoting API endpoints, allowing authenticated administrators to obtain session IDs and impersonate other users. It also includes privilege escalation through permission modification endpoints. Affected systems are dotCMS installations with vulnerable versions.
💻 Affected Systems
- dotCMS
⚠️ Manual Verification Required
This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.

- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Malicious administrator escalates privileges, modifies all role permissions, impersonates any user, and obfuscates audit trails, leading to complete system compromise and data exfiltration.
Likely Case
Administrator with legitimate access abuses exposed session IDs to impersonate other users or accesses sensitive user/role information they shouldn't have access to.
If Mitigated
With proper access controls and monitoring, impact is limited to authorized administrators accessing information they already have legitimate need for.
🎯 Exploit Status
Exploitation requires authenticated administrator access but involves simple API calls to exposed DWR endpoints.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 24.07.12, 23.01.20 LTS, 23.10.24v13 LTS, or 24.04.24v5 LTS
Vendor Advisory: https://www.dotcms.com/security/SI-72
Restart Required: Yes
Instructions:
1. Backup your dotCMS instance. 2. Download and apply the appropriate patch version for your release track. 3. Restart the dotCMS application server. 4. Verify the fix by checking version and testing affected endpoints.
🔧 Temporary Workarounds
Restrict DWR endpoint access
allConfigure web application firewall or reverse proxy to block access to vulnerable DWR endpoints
# Example nginx location block:
location ~* \.dwr$ {
deny all;
return 403;
}
Implement strict access controls
allReview and restrict administrator privileges, especially 'Sign In As' capabilities
🧯 If You Can't Patch
- Implement network segmentation to isolate dotCMS from sensitive systems
- Enable detailed logging and monitoring of all DWR endpoint access and administrator activities
🔍 How to Verify
Check if Vulnerable:
Check dotCMS version against affected versions. Test if authenticated admin can access /api/dwr/UserSessionAjax.getSessionList.dwr and retrieve session IDs.Check Version:
Check dotCMS admin panel or examine dotCMS/WEB-INF/lib/dotcms_*.jar versionVerify Fix Applied:
After patching, verify version is updated and test that DWR endpoints no longer expose sensitive session/user data to unauthorized administrators.📡 Detection & Monitoring
Log Indicators:
- Unusual DWR endpoint access patterns
- Multiple user impersonation events
- Role permission modifications from unexpected administrators
Network Indicators:
- HTTP requests to *.dwr endpoints with sensitive parameter names
- Unusual API token generation patterns
SIEM Query:
source="dotcms" AND (uri="*.dwr" OR method="POST" AND uri CONTAINS "ajax") AND (user_agent!="browser" OR referer="")
