Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-285: Improper Authorization, where the product does not perform or incorrectly performs an authorization check when an actor attempts to access a resource or perform an action. In Mantisbt/mantisbt, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### 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 ### Credits Thanks to [d3vpoo1](https://github.com/jrckmcsb) for reporting the issue.
