Microsoft SharePoint Page Content Vulnerabilities CVE-2015-1700
Remote code execution vulnerabilities exist when SharePoint Server improperly
sanitizes specially crafted page content. An authenticated attacker could
attempt to exploit these vulnerabilities by sending specially crafted page

vulnerabilities could run arbitrary code in the security context of the W3WP
service account on the target SharePoint site. Systems that are running an
affected version of SharePoint Server are primarily at risk.
The security update addresses the vulnerabilities by correcting how SharePoint
Server sanitizes specially crafted page content.
Microsoft received information about the vulnerabilities through coordinated

had not received any information to indicate that these vulnerabilities had
been publicly used to attack customers.
