Description

A flaw was found in fog-kubevirt. This vulnerability allows a remote attacker to perform a Man-in-the-Middle (MITM) attack due to disabled certificate validation. This enables the attacker to intercept and potentially alter sensitive communications between Satellite and OpenShift, resulting in information disclosure and data integrity compromise.

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.
