⚠️ Risk & Real-World Impact
Worst Case
An authenticated attacker could escalate privileges to administrative level, access sensitive system data, or modify critical Tanium configurations across the enterprise.
Likely Case
Authenticated users with standard privileges could access data or perform actions intended only for higher-privileged roles, potentially compromising sensitive information.
If Mitigated
With proper access controls and network segmentation, impact would be limited to authorized users accessing only slightly broader data sets than intended.
🎯 Exploit Status
Exploitation requires authenticated access to Tanium Interact and knowledge of the specific access control bypass. No public exploit code is available at this time.
