CVE-2024-36257

Mattermost versions 9.5.x <= 9.5.5 and 9.8.0, when using shared channels with multiple remote servers connected, fail to check that the remote server A requesting the server B to update the profile picture of a user is the remote that actually has the user as a local one . This allows a malicious remote A to change the profile images of users that belong to another remote server C that is connected to the server A.

Summary		(es) Las versiones 9.5.x <= 9.5.5 y 9.8.0 de Mattermost, cuando se utilizan canales compartidos con varios servidores remotos conectados, no verifican que el servidor remoto A que solicita al servidor B que actualice la imagen de perfil de un usuario sea el remoto que realmente tiene el usuario como local. Esto permite que un control remoto malicioso A cambie las imágenes de perfil de los usuarios que pertenecen a otro servidor remoto C que está conectado al servidor A.
