Official description

eLabFTW is an open source electronic lab notebook for research labs. In the context of eLabFTW, an administrator is a user account with certain privileges to manage users and content in their assigned team/teams. A user may be an administrator in one team and a regular user in another. The vulnerability allows a regular user to become administrator of a team where they are a member, under a reasonable configuration. Additionally, in eLabFTW versions subsequent to v5.0.0, the vulnerability may allow an initially unauthenticated user to gain administrative privileges over an arbitrary team. The vulnerability does not affect system administrator status. Users should upgrade to version 5.1.0. System administrators are advised to turn off local user registration, saml_team_create and not allow administrators to import users into teams, unless strictly required.

The underlying weakness: Incorrect Privilege Assignment

A product incorrectly assigns a privilege to a particular actor, creating an unintended sphere of control for that actor.

How developers prevent this class of flaw

  • Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
  • Run your code using the lowest privileges that are required to accomplish the necessary tasks. If possible, create isolated accounts with limited privileges that are only used for a single task. That way, a successful attack will not immediately give the attacker access to the rest of the software or its environment. For example, database applications rarely need to run as the database administrator, especially in day-to-day operations.
