Synopsis
The Microsoft Dynamics 365 (on-premises) is affected by a cross-site scripting vulnerability.Description
The Microsoft Dynamics 365 (on-premises) is missing security security updates. It is, therefore, affected by a cross-site scripting vulnerability due to not properly sanitizing specially crafted web requests. An authenticated attacker could exploit the vulnerability by sending a specially crafted request to an affected Dynamics server. 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 authenticated 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 within Dynamics Server 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 Dynamics Server properly sanitizes web requests.Note that Nessus has not attempted to exploit this issue but has instead relied only on the application's self-reported version number.
Solution
Microsoft has released the following security updates to address this issue:-KB4578106
-KB4578105
