Detailsinfo

A vulnerability classified as critical has been found in louislam uptime-kuma up to 1.23.8. Affected is some unknown functionality of the component Password Change Handler. The manipulation with an unknown input leads to a session fixiation vulnerability. CWE is classifying the issue as CWE-384. Authenticating a user, or otherwise establishing a new user session, without invalidating any existing session identifier gives an attacker the opportunity to steal authenticated sessions. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

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.

The weakness was published 12/12/2023 as GHSA-88j4-pcx8-q4q3. The advisory is available at github.com. This vulnerability is traded as CVE-2023-49804 since 11/30/2023. The technical details are unknown and an exploit is not available.

Upgrading to version 1.23.9 eliminates this vulnerability. Applying the patch 482049c72b3a650c7bc5c26c2f4d57a21c0e0aa0 is able to eliminate this problem. The bugfix is ready for download at github.com. The best possible mitigation is suggested to be upgrading to the latest version.
