Warpgate(Linux) vulnerability CVE-2023-48712
The vulnerability identified as CVE-2023-48712 affects Warpgate, an open-source SSH, HTTPS, and MySQL bastion host for Linux. In affected versions prior to 0.9.0, there is a privilege escalation vulnerability through a non-admin user's account. Limited users can impersonate another user's account if only single-factor authentication is configured. Specifically, if a user knows an admin username, opens the login screen, and attempts to authenticate with an incorrect password, they can subsequently enter a valid non-admin username and password and be logged in as the admin user. This poses a significant security risk as it allows unauthorized users to gain elevated privileges.
Given the severity of this vulnerability, all users are strongly advised to upgrade to version 0.9.0 or later. It's important to note that there are no known workarounds for this vulnerability, making the upgrade the only effective mitigation measure.
