Detailsinfo

A vulnerability classified as problematic has been found in Barracuda Web Filter 6.0.1.009. This affects an unknown code block of the component Add Domain Page. The manipulation of the argument grid__data/grid_columns/x-grid3-cell-inner/x-grid3-col-name with an unknown input leads to a cross site scripting vulnerability. CWE is classifying the issue as CWE-80. The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special characters such as "<", ">", and "&" that could be interpreted as web-scripting elements when they are sent to a downstream component that processes web pages. This is going to have an impact on integrity.
