GroupOffice's Blind Stored XSS in Phone Number Field Enables Forced Redirect and Unauthorized Actions

Group-Office is an enterprise customer relationship management and groupware tool. Prior to versions 6.8.119 and 25.0.20, a stored and blind XSS vulnerability exists in the Phone Number field of the user profile within the GroupOffice application.

Versions 6.8.119 and 25.0.20 contain a fix for the issue.
