CVE-2024-7475
📋 TL;DR
This vulnerability allows unauthorized attackers to modify SAML configuration settings in lunary-ai/lunary version 1.3.2. This can lead to authentication bypass, fraudulent logins, and potential user data theft. Organizations using this specific version of the lunary software are affected.
💻 Affected Systems
- lunary-ai/lunary
📦 What is this software?
Lunary by Lunary
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of authentication system allowing attackers to impersonate any user, steal sensitive data, and maintain persistent access to the system.
Likely Case
Authentication bypass enabling unauthorized access to user accounts and potential data exfiltration.
If Mitigated
No impact if proper access controls prevent unauthorized SAML configuration changes.
🎯 Exploit Status
Exploitation requires network access to the lunary instance but does not require authentication to modify SAML configuration.
