deepthi published GHSA-735r-hv67-g38f Apr 11, 2023

Package

gomod vitess (Go)

Affected versions

< 16.0.1

Patched versions

16.0.1

Description

Impact

Users can either intentionally or inadvertently create a keyspace containing / characters such that from that point on, anyone who tries to view keyspaces from VTAdmin will receive an error. Trying to list all the keyspaces using vtctldclient GetKeyspaces will also return an error.
Note that all other keyspaces can still be administered using the CLI (vtctldclient).

Patches

v16.0.1

Workarounds

Delete the offending keyspace using a CLI client (vtctldclient)

vtctldclient --server ... DeleteKeyspace a/b

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.
