Multiple vulnerabilities in Symantec Endpoint Protection Manager

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, according to Secunia.

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.

The vulnerabilities are confirmed in version 11.0.6 Maintenance Patch 2 (11.0.6200.754). Other versions may also be affected.

Solution: Update to version 11.0.7000 RU7.
