CVE-2020-16944 – Microsoft SharePoint Reflective XSS Vulnerability
https://notcve.org/view.php?id=CVE-2020-16944
<p>This vulnerability is caused when SharePoint Server does not properly sanitize a specially crafted request to an affected SharePoint server.</p> <p>An authenticated attacker could exploit this vulnerability by sending a specially crafted request to an affected SharePoint server. The attacker who successfully exploited this 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 SharePoint site on behalf of the victim, such as change permissions, delete content, steal sensitive information (such as browser cookies) and inject malicious content in the browser of the victim.</p> <p>For this vulnerability to be exploited, a user must click a specially crafted URL that takes the user to a targeted SharePoint Web App site. • https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2020-16944 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
