CVE-2020-1523

Estado: ModificadaMedia (4.3)—

<p>A tampering vulnerability exists when Microsoft SharePoint Server fails to properly handle profile data. An attacker who successfully exploited this vulnerability could modify a targeted user's profile data.</p> <p>To exploit the vulnerability, an attacker would need to be authenticated on an affected SharePoint Server. The attacker would then need to send a specially modified request to the server, targeting a specific user.</p> <p>The security update addresses the vulnerability by modifying how Microsoft SharePoint Server handles profile data.</p>
