Sealos is an open source cloud operating system distribution based on the Kubernetes kernel. In versions of Sealos prior to 4.2.1-rc4 an improper configuration of role based access control (RBAC) permissions resulted in an attacker being able to obtain cluster control permissions, which could control the entire cluster deployed with Sealos, as well as hundreds of pods and other resources within the cluster. This issue has been addressed in version 4.2.1-rc4. Users are advised to upgrade. There are no known workarounds for this vulnerability.Show less

A vulnerability in Cisco Duo Two-Factor Authentication for macOS could allow an authenticated, physical attacker to bypass secondary authentication and access an affected macOS device. This vulnerability is due to the incorrect handling of responses from Cisco Duo when the application is configured to fail open. An attacker with primary user credentials could exploit this vulnerability by attempting to authenticate to an affected device. A successful exploit could allow the attacker to access the affected device without valid permission.Show less

pam_krb5 authenticates a user by essentially running kinit with the password, getting a ticket-granting ticket (tgt) from the Kerberos KDC (Key Distribution Center) over the network, as a way to verify the password. However, if a keytab is not provisioned on the system, pam_krb5 has no way to validate the response from the KDC, and essentially trusts the tgt provided over the network as being valid. In a non-default FreeBSD installation that leverages pam_krb5 for authentication and does not have a keytab provisioned, an attacker that is able to control both the password and the KDC responses can return a valid tgt, allowing authentication to occur for any user on the system.
