Description

MantisBT unauthorized disclosure of private project column configuration

Impact

Due to insufficient access-level checks, any non-admin user having access to _manage_config_columns_page.php_ (typically project managers having MANAGER role) can use the _Copy From_ action to retrieve the columns configuration from a private project they have no access to.

Access to the reverse operation (_Copy To_) is correctly controlled, i.e. it is not possible to alter the private project's configuration.

Patches

The vulnerability will be fixed in MantisBT version 2.27.2.

Workarounds

None
