CubeFS leaks users key in logs

Moderate

Package

Affected versions

< v3.3.1

Patched versions

v3.3.1

Description

CubeFS was found to leak users secret keys and access keys in the logs in multiple components. When CubeCS creates new users, it leaks the users secret key. This could allow a lower-privileged user with access to the logs to retrieve sensitive information and impersonate other users with higher privileges than themselves.

There is no evidence of this vulnerability being exploited in the wild. It was found during an ongoing security audit carried out by Ada Logics in collaboration with OSTIF and the CNCF.

The issue has been patched in v3.3.1. There is no other mitigation than upgrading CubeFS.

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.
