critical Web App Scanning Plugin ID 115819

Synopsis

Kentico Xperience CMS 13.x < 13.0.179 Staging Service Authentication Bypass

Description

Kentico CMS is a common ASP.NET Content Management System (CMS) used for building websites and online stores.

Kentico Xperience 13 versions through 13.0.178 are affected by an authentication bypass in the Staging Sync Server component due to improper handling of the server-defined None password type. When the Staging Service is enabled, an unauthenticated attacker can exploit this flaw to gain control of administrative objects, potentially compromising the CMS.

Solution

Upgrade Kentico Xperience 13 to hotfix 179 (13.0.179) or later.
