PrivateVPN 2.0.31 for macOS suffers from a root privilege escalation vulnerability. The software installs a privileged helper tool that runs as the root user. This privileged helper tool is installed as a LaunchDaemon and implements an XPC service. The XPC service is responsible for handling new VPN connection operations via the main PrivateVPN application. The privileged helper tool creates new VPN connections by executing the openvpn binary located in the /Applications/PrivateVPN.app/Contents/Resources directory. The openvpn binary can be overwritten by the default user, which allows an attacker that has already installed malicious software as the default user to replace the binary. When a new VPN connection is established, the privileged helper tool will launch this malicious binary, thus allowing an attacker to execute code as the root user. NOTE: the vendor has reportedly indicated that this behavior is "an acceptable part of their software.

An issue was discovered in Hola 1.79.859. An unprivileged user could modify or overwrite the executable with arbitrary code, which would be executed the next time the service is started. Depending on the user that the service runs as, this could result in privilege escalation. The issue exists because of the SERVICE_ALL_ACCESS access right for the hola_svc and hola_updater services.

Read-Only export policy rules are not correctly enforced in Clustered Data ONTAP 8.3 Release Candidate versions and therefore may allow more than "read-only" access from authenticated SMBv2 and SMBv3 clients. This behavior has been resolved in the GA release. Customers running prior release candidates (RCs) are requested to update their systems to the NetApp Data ONTAP 8.3 GA release.

An exploitable Permission Assignment vulnerability exists in the ACEManager EmbeddedAceSet_Task.cgi functionality of Sierra Wireless AirLink ES450 FW 4.9.3. The EmbeddedAceSet_Task.cgi executable is used to change MSCII configuration values within the configuration manager of the AirLink ES450. This binary does not have any restricted configuration settings, so once the MSCIID is discovered, any authenticated user can send configuration changes using the /cgi-bin/Embedded_Ace_Set_Task.cgi endpoint.

Talos worker join token can be used to get elevated access level to the Talos API

Talos Linux is a Linux distribution built for Kubernetes deployments. Talos worker nodes use a join token to get accepted into the Talos cluster. Due to improper validation of the request while signing a worker node CSR (certificate signing request) Talos control plane node might issue Talos API certificate which allows full access to Talos API on a control plane node. Accessing Talos API with full level access on a control plane node might reveal sensitive information which allows full level access to the cluster (Kubernetes and Talos PKI, etc.). Talos API join token is stored in the machine configuration on the worker node. When configured correctly, Kubernetes workloads don't have access to the machine configuration, but due to a misconfiguration workload might access the machine configuration and reveal the join token. This problem has been fixed in Talos 1.2.2. Enabling the Pod Security Standards mitigates the vulnerability by denying hostPath mounts and host networking by default in the baseline policy. Clusters that don't run untrusted workloads are not affected. Clusters with correct Pod Security configurations which don't allow hostPath mounts, and secure access to cloud metadata server (or machine configuration is not supplied via cloud metadata server) are not affected.

External Secrets Operator vulnerable to privilege escalation

External Secrets Operator is a Kubernetes operator that integrates external secret management systems. The external-secrets has a deployment called default-external-secrets-cert-controller, which is bound with a same-name ClusterRole. This ClusterRole has "get/list" verbs of secrets resources. It also has path/update verb of validatingwebhookconfigurations resources. This can be used to abuse the SA token of the deployment to retrieve or get ALL secrets in the whole cluster, capture and log all data from requests attempting to update Secrets, or make a webhook deny all Pod create and update requests. This vulnerability is fixed in 0.10.2.

PowerPack Pro for Elementor <= 2.10.17 - Authenticated (Contributor+) Privilege Escalation

The PowerPack Pro for Elementor plugin for WordPress is vulnerable to privilege escalation in all versions up to, and including, 2.10.17. This is due to the plugin not restricting low privileged users from setting a default role for a registration form. This makes it possible for authenticated attackers, with contributor-level access and above, to create a registration form with administrator set as the default role and then register as an administrator.

Cloud Foundry CAPI (Cloud Controller), versions prior to 1.97.0, when used in a deployment where an app domain is also the system domain (which is true in the default CF Deployment manifest), were vulnerable to developers maliciously or accidentally claiming certain sensitive routes, potentially resulting in the developer's app handling some requests that were expected to go to certain system components.
