This can be exploited to insert arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site when the malicious data is viewed. 2) Input passed via the "Full Name" field to Administrators of the Administrators section, via the Name and Description fields to Categories of the "Filtering & Protection" section, via the Name field to Identify of the Identification section, via the Username field to Users of the "Users & Groups" section, via the Name and Description fields to Groups of the "Users & Groups" section, via Name and Description fields to "Filtering Policies", via the "Original URL" and Redirection fields to "Proxy & Cache", via the Destination field to Email of the Alerts section, via the Name field to "Access Denied Page" of the "Appliance Customization" section, via the Name field to "Login Page" of the "Appliance Customization" section, via the Name field to "Logout Denied Page" of the "Appliance Customization" section is not properly sanitised before being used. This can be exploited to insert arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site if malicious data is viewed. 3) The application allows users to perform certain actions via HTTP requests without performing any validity checks to verify the requests. This can be exploited to cause unspecified impacts by tricking a logged in administrator into visiting a malicious web site. 4) Input passed via the URL when using HTTPS is not properly sanitised before being returned to the user in a Microdasys SSL error page. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site. Successful exploitation requires that the target server of the URL does not support HTTPS. 5) An error due to the application not properly verifying the X-Forwarded-For HTTP header can be exploited to bypass IP restrictions and access blocked sites. The vulnerabilities are reported in versions prior to 5.0.14. SOLUTION: Update to version 5.0.14. PROVIDED AND/OR DISCOVERED BY: US-CERT credits Travis Lee.
