SoftIron HyperCloud 2.5.0 through 2.6.3 may incorrectly add user SSH keys to the administrator-level authorized keys under certain conditions, allowing unauthorized privilege escalation to admin via SSH. Affects non-production debug and internal development builds created between versions 2.5.0 and 2.6.3.  No generally available (GA) or customer-released production builds were affected.  There is no evidence that this issue was exposed in customer environments or production deployments.

An issue exists in SoftIron HyperCloud where authenticated, but non-admin users can create data pools, which could potentially impact the performance and availability of the backend software-defined storage subsystem.

This issue only impacts SoftIron HyperCloud and related software products (such as VM Squared) software versions 2.3.0 to before 2.5.0.

Cloud hypervisor is a Virtual Machine Monitor for Cloud workloads. This vulnerability allows users to close arbitrary open file descriptors in the Cloud Hypervisor process via sending malicious HTTP request through the HTTP API socket. As a result, the Cloud Hypervisor process can be easily crashed, causing Deny-of-Service (DoS). This can also be a potential Use-After-Free (UAF) vulnerability. Users require to have the write access to the API socket file to trigger this vulnerability. Impacted versions of Cloud Hypervisor include upstream main branch, v31.0, and v30.0. The vulnerability was initially detected by our httpapifuzzer via oss-fuzz. This issue has been addressed in versions 30.1 and 31.1. Users unable to upgrade may mitigate this issue by ensuring the write access to the API socket file is granted to trusted users only.

An issue exists in SoftIron HyperCloud where drive caddy removal and reinsertion without a reboot may erroneously cause the system to recognize the caddy as new media and wipe all data on the drives due to a missing synchronization flaw, which impacts data availability and integrity.

This issue only impacts SoftIron HyperCloud "density" storage nodes running HyperCloud software versions 1.0 to before 2.0.3.

An Improper Privilege Management vulnerability exists in HyperCloud that will impact the ability for a user to authenticate against the management plane.

An authenticated admin-level user may be able to delete the "admin" or "serveradmin" users, which prevents authentication from subsequently succeeding.

This issue affects HyperCloud versions 1.0 to any release before 2.1.

An issue exists in SoftIron HyperCloud where compute nodes may come online immediately without following the correct initialization process.  In this instance, workloads may be scheduled on these nodes and deploy to a failed or erroneous state, which impacts the availability of these workloads that may be deployed during this time window.

This issue impacts HyperCloud versions from 2.0.0 to before 2.0.3.
