Description

A flaw was found in the search-v2-operator. This vulnerability allows a privileged user, specifically a Custom Resource (CR) editor, to manipulate Search CR fields such as imageOverride, arguments, and environment variables without proper validation. By exploiting this, an attacker can mount arbitrary secrets into a search container's environment or replace the container image with an attacker-controlled one. This leads to privilege escalation and can result in a full cluster compromise due to the ServiceAccount's extensive impersonation permissions.

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.
CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H
