An elevation of privilege vulnerability exists when Microsoft Identity Manager 2016 SP1 Service and Portal does not properly sanitize a specially crafted attribute value being displayed to a user on an affected MIM 2016 server. An attacker could exploit the vulnerability by sending a specially crafted request to an affected MIM 2016 deployment. 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 MIM Portal 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 MIM 2016 Server properly sanitizes displayed attributes.
