Description

Summary

General users can access information that can only be accessed by users with access privileges to admin and support information (SETTINGS_SUPPORT).

Details

General users can access information that can only be accessed by users with access privileges to admin and support information (SETTINGS_SUPPORT). This is due to inadequate access control for support information (http://<opencti_domain>/storage/get/support/UUID/UUID.zip), and that the UUID is available to general users using an attached query (logs query).

Impact

An attacker with general user privileges can gain unauthorized access to software and OS version information and so on that can only be accessed by admin. This allows them to collect information necessary for their additional attacks, which may lead to further damage.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
