Description

Summary

Yeti is subject to a remote code execution vulnerability. The remote code execution arises from the ability to create custom templates. An authenticated user can create a template with specifically crafted strings to remotely execute arbitrary code on the server.

Impact

An authenticated user could upload a specially crafted template, that when executed in the context of an export, could provide arbitrary code execution on the worker node executing the export.

Affected versions

Versions prior to 2.1.12 are affected by this vulnerability. The patch is included in 2.1.12.

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.
