https://notcve.org/view.php?id=CVE-2020-1453
<p>A remote code execution vulnerability exists in Microsoft SharePoint when the software fails to check the source markup of an application package. An attacker who successfully exploited the vulnerability could run arbitrary code in the context of the SharePoint application pool and the SharePoint server farm account.</p> <p>Exploitation of this vulnerability requires that a user uploads a specially crafted SharePoint application package to an affected version of SharePoint.</p> <p>The security update addresses the vulnerability by correcting how SharePoint checks the source markup of application packages.</p> Se presenta una vulnerabilidad de ejecución de código remota en Microsoft SharePoint cuando el software presenta un fallo al comprobar el código fuente de un paquete de aplicación, también se conoce como "Microsoft SharePoint Remote Code Execution Vulnerability". • https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2020-1453 • CWE-494: Download of Code Without Integrity Check •
CVE-2020-1440 – Microsoft SharePoint Server Tampering Vulnerability
https://notcve.org/view.php?id=CVE-2020-1440
<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. • https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2020-1440 •

CVE-2020-1345 – Microsoft Office SharePoint XSS Vulnerability
https://notcve.org/view.php?id=CVE-2020-1345
<p>A cross-site-scripting (XSS) vulnerability exists when Microsoft SharePoint Server does not properly sanitize a specially crafted web request to an affected SharePoint server. An authenticated attacker could exploit the vulnerability by sending a specially crafted request to an affected SharePoint server.</p> <p>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. The 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 user, such as change permissions and delete content, and inject malicious content in the browser of the user.</p> <p>The security update addresses the vulnerability by helping to ensure that SharePoint Server properly sanitizes web requests. • https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2020-1345 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
CVE-2020-1335 – Microsoft Excel Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2020-1335
<p>A remote code execution vulnerability exists in Microsoft Excel software when the software fails to properly handle objects in memory. An attacker who successfully exploited the vulnerability could run arbitrary code in the context of the current user. If the current user is logged on with administrative user rights, an attacker could take control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights. • https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2020-1335 •
