Kanboard is Vulnerable to Reverse Proxy Authentication Bypass

Résumé

Kanboard is Vulnerable to Reverse Proxy Authentication Bypass

Description d'origine

La description telle que publiée par la source (souvent en anglais).

Kanboard is project management software focused on Kanban methodology. Versions 1.2.48 and below is vulnerable to a critical authentication bypass when REVERSE_PROXY_AUTH is enabled. The application blindly trusts HTTP headers for user authentication without verifying the request originated from a trusted reverse proxy. An attacker can impersonate any user, including administrators, by simply sending a spoofed HTTP header. This issue is fixed in version 1.2.49.
