"The Microsoft SharePoint Server installation on the remote
host is missing security updates. It is, therefore, affected
by multiple vulnerabilities :
- A cross-site-scripting (XSS) vulnerability exists when
Microsoft SharePoint Server does not properly sanitize a
specially crafted web request to an affected SharePoint
server. An authenticated attacker could exploit the
vulnerability by sending a specially crafted request to
an affected SharePoint server. The attacker who
successfully exploited the vulnerability could then
perform cross-site scripting attacks on affected systems
and run script in the security context of the current
user. The attacks could allow the attacker to read
content that the attacker is not authorized to read, use
the victim's identity to take actions on the SharePoint
site on behalf of the user, such as change permissions
and delete content, and inject malicious content in the
browser of the user. The security update addresses the
vulnerability by helping to ensure that SharePoint
Server properly sanitizes web requests. (CVE-2019-1070)
- A spoofing vulnerability exists when Microsoft
SharePoint Server does not properly sanitize a specially
crafted web request to an affected SharePoint server. An
authenticated attacker could exploit the vulnerability
by sending a specially crafted request to an affected
SharePoint server. The attacker who successfully
exploited the vulnerability could then perform cross-
site scripting attacks on affected systems and run
script in the security context of the current user.
These attacks could allow the attacker to read content
that the attacker is not authorized to read, use the
victim's identity to take actions on the SharePoint site
on behalf of the user, such as change permissions and
delete content, and inject malicious content in the
browser of the user. The security update addresses the
vulnerability by helping to ensure that SharePoint
Server properly sanitizes web requests. (CVE-2019-1328)
- An elevation of privilege vulnerability exists when
Microsoft SharePoint Server does not properly sanitize a
specially crafted web request to an affected SharePoint
server. An authenticated attacker could exploit the
vulnerability by sending a specially crafted request to
an affected SharePoint server. The attacker who
successfully exploited the vulnerability could then
perform cross-site scripting attacks on affected systems
and run script in the security context of the current
user. These attacks could allow the attacker to read
content that the attacker is not authorized to read, use
the victim's identity to take actions on the SharePoint
site on behalf of the user, such as change permissions
and delete content, and inject malicious content in the
browser of the user. The security update addresses the
vulnerability by helping to ensure that SharePoint
Server properly sanitizes web requests. (CVE-2019-1329)
- An elevation of privilege vulnerability exists in
Microsoft SharePoint. An attacker who successfully
exploited this vulnerability could attempt to
impersonate another user of the SharePoint server.
(CVE-2019-1330)
- A remote code execution vulnerability exists in
Microsoft Excel software when the software fails to
properly handle objects in memory. An attacker who
successfully exploited the vulnerability could run
arbitrary code in the context of the current user. If
the current user is logged on with administrative user
rights, an attacker could take control of the affected
system. An attacker could then install programs; view,
change, or delete data; or create new accounts with full
user rights. (CVE-2019-1331)");
