Synopsis

The Microsoft Exchange Server installed on the remote host is affected by multiple vulnerabilities.

Description

The Microsoft Exchange Server installed on the remote host is missing security updates. It is, therefore, affected by multiple vulnerabilities :

 - An information disclosure vulnerability exists in the way that Microsoft Exchange Server handles URL redirects. If an impacted user is using Microsoft Exchange Outlook Web Access (OWA) Light, the vulnerability could allow an attacker to discover sensitive information that should otherwise not be disclosed, such as the URL of the user's OWA service.
 (CVE-2018-0924)

 - An information disclosure vulnerability exists in the way that Microsoft Exchange Server handles importing data. If an impacted user is using Microsoft Exchange Outlook Web Access (OWA), the vulnerability could allow an attacker to discover sensitive information that should otherwise not be disclosed. (CVE-2018-0941)

 - An elevation of privilege vulnerability exists when Microsoft Exchange Outlook Web Access (OWA) fails to properly sanitize links presented to users. An attacker who successfully exploited this vulnerability could override the OWA interface with a fake login page and attempt to trick the user into disclosing sensitive information. (CVE-2018-0940)

Solution

Microsoft has released advisories to address these issues.
