Tanium addressed a local privilege escalation vulnerability in Patch Endpoint Tools.
Weakness
The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.
Affected Software
| Name | Vendor | Start Version | End Version |
|---|---|---|---|
| Endpoint_configuration_toolset_solution | Tanium | * | 1.40.37 (excluding) |
| Patch_endpoint_tools | Tanium | 3.17 (including) | 3.17.10195 (excluding) |

| Patch_endpoint_tools | Tanium | 10.2 (including) | 10.2.22 (excluding) |
Potential Mitigations
- Follow the principle of least privilege when assigning access rights to entities in a software system.
- Denying access to a file can prevent an attacker from replacing that file with a link to a sensitive file. Ensure good compartmentalization in the system to provide protected areas that can be trusted.
