Multiple vulnerabilities have been discovered in Symantec Endpoint Protection Manager, which can be exploited by malicious people to conduct cross-site scripting and request forgery attacks.

1) Input appended to the URL after /console/apps/sepm is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

2) Input passed via the "token" parameter to portal/Help.jsp is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

3) The portal application allows users to perform certain actions via HTTP requests without performing any validity checks to verify the requests. This can be exploited to e.g. add an administrative user by tricking a logged in administrator into visiting a malicious web site.

4) Input passed via the "Msg" parameter to portal/TestConnection.jsp is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
