MS15-064: Vulnerabilities in Microsoft Exchange Server Could Allow Elevation of Privilege (3062157)

This script is Copyright (C) 2015-2017 Tenable Network Security, Inc.


Synopsis :

The remote Microsoft Exchange server is affected by multiple
vulnerabilities.

Description :

The remote Microsoft Exchange server is missing a security update. It
is, therefore, affected by multiple vulnerabilities :

- A server-side request forgery vulnerability exists in
Microsoft Exchange web applications due to improper
management of same-origin policy. An attacker can
exploit this by using a specially crafted web
application, allowing further attacks to be carried
out. (CVE-2015-1764)

- An cross-site request forgery vulnerability exists in
Microsoft Exchange web applications due to improper
management of user sessions. A remote attacker can
exploit this by tricking a user into visiting a
specially crafted web page, resulting in gaining access
to sensitive information, impersonating the user's
identity, or injecting malicious content into the
victim's web browser. (CVE-2015-1771)

- An HTML injection vulnerability exists in Microsoft
Exchange web applications due to not properly sanitizing
user-supplied HTML strings. A remote attacker can
exploit this by submitting a crafted script to a target
site that uses HTML sanitization, resulting in the
execution of malicious code in the security context of
the user visiting the site. (CVE-2015-2359)
