Multiple SharePoint XSS Vulnerabilities
Elevation of privilege vulnerabilities exist when SharePoint Server does not
properly sanitize a specially crafted request to an affected SharePoint
server. An authenticated attacker could exploit these vulnerabilities by
sending a specially crafted request to an affected SharePoint server. The
attacker who successfully exploited these vulnerabilities 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 victim, such
as change permissions and delete content, and inject malicious content in the
browser of the victim.
The security update addresses the vulnerabilities by helping to ensure that
SharePoint Server properly sanitizes user input.
Microsoft received information about the vulnerabilities through coordinated
vulnerability disclosure. When this security bulletin was issued, Microsoft
had not received any information to indicate that these vulnerabilities had
been publicly used to attack customers.
