eLabFTW is an electronic lab notebook manager for research teams. Prior to version 4.3.0, a vulnerability allows an authenticated user with an administrator role in a team to assign itself system administrator privileges within the application, or create a new system administrator account. The issue has been corrected in eLabFTW version 4.3.0. In the context of eLabFTW, an administrator is a user account with certain privileges to manage users and content in their assigned team/teams.

Read full descriptionShow less

A system administrator account can manage all accounts, teams and edit system-wide settings within the application. The impact is not deemed as high, as it requires the attacker to have access to an administrator account. Regular user accounts cannot exploit this to gain admin rights. A workaround for one if the issues is removing the ability of administrators to create accounts.

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.

⚠️ GitHub proofs of concept are not verified: some are fake or contain malware. Never run them outside an isolated lab.

En versiones anteriores a 4.3.0, una vulnerabilidad permite a un usuario autenticado con un rol de administrador en un equipo asignarse a sí mismo privilegios de administrador del sistema dentro de la aplicación, o crear una nueva cuenta de administrador del sistema. El problema ha sido corregido en eLabFTW versión 4.3.0. En el contexto de eLabFTW, un administrador es una cuenta de usuario con ciertos privilegios para administrar usuarios y contenidos en su equipo/equipos asignados. Una cuenta de administrador del sistema puede administrar todas las cuentas, equipos y editar la configuración de todo el sistema dentro de la aplicación. El impacto no es considerado tan alto, ya que requiere que el atacante tenga acceso a una cuenta de administrador. Las cuentas de usuarios normales no pueden aprovechar esta situación para obtener derechos de administrador. Una mitigación para uno de los problemas es eliminar la capacidad de los administradores para crear cuentas"
