KubeVirt is a virtual machine management add-on for Kubernetes. Prior to 1.5.3 and 1.6.1, due to the peer verification logic in virt-handler (via verifyPeerCert), an attacker who compromises a virt-handler instance, could exploit these shared credentials to impersonate virt-api and execute privileged operations against other virt-handler instances potentially compromising the integrity and availability of the VM managed by it. This vulnerability is fixed in 1.5.3 and 1.6.1.Show less

KubeVirt is a virtual machine management add-on for Kubernetes. Versions 1.5.3 and below, and 1.6.0 contained a flawed implementation of the Kubernetes aggregation layer's authentication flow which could enable bypass of RBAC controls. It was discovered that the virt-api component fails to correctly authenticate the client when receiving API requests over mTLS. In particular, it fails to validate the CN (Common Name) field in the received client TLS certificates against the set of allowed values defined in the extension-apiserver-authentication configmap. Failre to validate certain fields in the client TLS certificate may allow an attacker to bypass existing RBAC controls by directly communicating with the aggregated API server, impersonating the Kubernetes API server and its aggregator component. This issue is fixed in versions 1.5.3 and 1.6.1.Show less

Starting from 2.53.6, 2.54.3, and 2.55.0, Zitadel only required multi factor authentication in case the login policy has either enabled requireMFA or requireMFAForLocalUsers. If a user has set up MFA without this requirement, Zitadel would consider single factor auhtenticated sessions as valid as well and not require multiple factors. Bypassing second authentication factors weakens multifactor authentication and enables attackers to bypass the more secure factor. An attacker can target the TOTP code alone, only six digits, bypassing password verification entirely and potentially compromising accounts with 2FA enabled. This vulnerability is fixed in 4.6.0, 3.4.3, and 2.71.18.Show less

OctoPrint-SpoolManager is a plugin for managing spools and all their usage metadata. In versions 1.8.0a2 and older of the testing branch and versions 1.7.7 and older of the stable branch, the APIs of the OctoPrint-SpoolManager plugin do not correctly enforce authentication or authorization checks. This issue has been patched in versions 1.8.0a3 of the testing branch and 1.7.8 of the stable branch. The impact of this vulnerability is greatly reduced when using OctoPrint version 1.11.2 and newer.Show less

The communication protocol implemented in Ghost Robotics Vision 60 v0.27.2 could allow an attacker to send commands to the robot from an external attack station, impersonating the control station (tablet) and gaining unauthorised full control of the robot. The absence of encryption and authentication mechanisms in the communication protocol allows an attacker to capture legitimate traffic between the robot and the controller, replicate it, and send any valid command to the robot from any attacking computer or device. The communication protocol used in this interface is based on MAVLink, a widely documented protocol, which increases the likelihood of attack. There are two methods for connecting to the robot remotely: Wi-Fi and 4G/LTE.Show less
