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.
