Ektron CMS Account Hijack
Description
Ektron Web Content Management System (CMS), a .NET-based enterprise content management platform, contains an authentication bypass vulnerability that allows unauthorized access to administrative functions. The vulnerability exists in the /WorkArea/edituserprofile.aspx page, which can be accessed directly without proper authentication checks. This flaw enables attackers to modify user profiles, including administrator and built-in system accounts, leading to complete system compromise.
Remediation
Apply the following remediation steps immediately:
1. Upgrade Ektron CMS: Update to the latest patched version of Ektron CMS that addresses this authentication bypass vulnerability. Contact Ektron support or check the vendor's security advisories for the specific version that resolves this issue.
2. Implement Access Controls: Until the upgrade can be completed, restrict access to the /WorkArea/ directory using web server-level access controls. For IIS, add the following to your web.config:
<location path="WorkArea">
<system.web>
<authorization>
<deny users="?" />
</authorization>
</system.web>
</location>3. Network Segmentation: If possible, restrict access to the /WorkArea/ path to trusted IP addresses or internal networks only using firewall rules or web application firewall (WAF) policies.
4. Monitor for Exploitation: Review web server logs for suspicious access attempts to /WorkArea/edituserprofile.aspx and check for unauthorized changes to user accounts, particularly administrative accounts.
5. Verify Account Integrity: Audit all user accounts, especially administrative and built-in accounts, to ensure no unauthorized modifications have been made.
