Vulnerability Information

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.
