Description
Incus is a system container and virtual machine manager. Prior to version 6.23.0, a specially crafted storage bucket backup can be used by an user with access to Incus' storage bucket feature to crash the Incus daemon. Repeated use of this attack can be used to keep the server offline causing a denial of service of the control plane API. This does not impact any running workload, existing containers and virtual machines will keep operating. Version 6.23.0 fixes the issue.
Analysis
Denial of service in Incus prior to version 6.23.0 allows authenticated users with storage bucket access to crash the Incus daemon via specially crafted storage bucket backups, enabling repeated attacks to render the control plane API unavailable while leaving running workloads unaffected. The vulnerability requires local or remote authentication to the Incus system and has a CVSS score of 6.5 (medium severity) with high availability impact. …
