Overview

CVE-2023-49804 is a medium-severity vulnerability. It was published on December 11, 2023 and has a CVSS 3.1 base score of 6.7 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 6.7, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

Uptime Kuma is an easy-to-use self-hosted monitoring tool. Prior to version 1.23.9, when a user changes their login password in Uptime Kuma, a previously logged-in user retains access without being logged out. This behavior persists consistently, even after system restarts or browser restarts. This vulnerability allows unauthorized access to user accounts, compromising the security of sensitive information. The same vulnerability was partially fixed in CVE-2023-44400, but logging existing users out of their accounts was forgotten. To mitigate the risks associated with this vulnerability, the maintainers made the server emit a `refresh` event (clients handle this by reloading) and then disconnecting all clients except the one initiating the password change. It is recommended to update Uptime Kuma to version 1.23.9.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
