CVE-2020-1476 – ASP.NET and .NET Elevation of Privilege Vulnerability
https://notcve.org/view.php?id=CVE-2020-1476
An elevation of privilege vulnerability exists when ASP.NET or .NET web applications running on IIS improperly allow access to cached files. An attacker who successfully exploited this vulnerability could gain access to restricted files. To exploit this vulnerability, an attacker would need to send a specially crafted request to an affected server. The update addresses the vulnerability by changing how ASP.NET and .NET handle requests. Se presenta una vulnerabilidad de elevación de privilegios cuando las aplicaciones web ASP.NET o .NET que se ejecutan en IIS, permiten inapropiadamente el acceso a archivos almacenados en caché, también se conoce como "ASP.NET and .NET Elevation of Privilege Vulnerability". • https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2020-1476 •
CVE-2020-1046 – .NET Framework Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2020-1046
A remote code execution vulnerability exists when Microsoft .NET Framework processes input. An attacker who successfully exploited this vulnerability could take control of an affected system. To exploit the vulnerability, an attacker would need to be able to upload a specially crafted file to a web application. The security update addresses the vulnerability by correcting how .NET Framework processes input. Se presenta una vulnerabilidad de ejecución de código remota cuando Microsoft .NET Framework procesa una entrada, también se conoce como ".NET Framework Remote Code Execution Vulnerability". • https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2020-1046 •
CVE-2020-1147 – Microsoft .NET Framework, SharePoint, and Visual Studio Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2020-1147
A remote code execution vulnerability exists in .NET Framework, Microsoft SharePoint, and Visual Studio when the software fails to check the source markup of XML file input, aka '.NET Framework, SharePoint Server, and Visual Studio Remote Code Execution Vulnerability'. Se presenta una vulnerabilidad de ejecución de código remota en .NET Framework, Microsoft SharePoint y Visual Studio cuando el software presenta un fallo al comprobar el marcado de origen de una entrada de archivo XML, también se conoce como ".NET Framework, SharePoint Server, and Visual Studio Remote Code Execution Vulnerability" It was discovered that .NET Core did not properly check the source markup of XML files. A remote, unauthenticated attacker could possibly exploit this flaw to execute arbitrary code by sending specially crafted requests to an application parsing certain kinds of XML files or an ASP.NET Core application. Microsoft .NET Framework, Microsoft SharePoint, and Visual Studio contain a remote code execution vulnerability when the software fails to check the source markup of XML file input. Successful exploitation allows an attacker to execute code in the context of the process responsible for deserialization of the XML content. • https://www.exploit-db.com/exploits/48747 https://www.exploit-db.com/exploits/50151 http://packetstormsecurity.com/files/158694/SharePoint-DataSet-DataTable-Deserialization.html http://packetstormsecurity.com/files/158876/Microsoft-SharePoint-Server-2019-Remote-Code-Execution.html http://packetstormsecurity.com/files/163644/Microsoft-SharePoint-Server-2019-Remote-Code-Execution.html https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2020-1147 https://www.exploitalert.com/view-details.html?id=35992 h • CWE-502: Deserialization of Untrusted Data •
CVE-2020-1108 – dotnet: Denial of service via untrusted input
https://notcve.org/view.php?id=CVE-2020-1108
A denial of service vulnerability exists when .NET Core or .NET Framework improperly handles web requests, aka '.NET Core & .NET Framework Denial of Service Vulnerability'. Se presenta una vulnerabilidad denegación de servicio cuando .NET Core o .NET Framework manejan inapropiadamente las peticiones web, también se conoce como ".NET Core & .NET Framework Denial of Service Vulnerability" An integer overflow condition was found in dotnet and dotnet3.1's BinaryReader Read7BitEncodedInt() method. This method is used by BinaryReader's ReadString() method, and given a certain input, and cause a denial of service to dotnet applications using BinaryReader. The exploitation of this flaw depends on the application but does not inherently require the attacker to be authenticated or have any specific privileges. An attacker could exploit this flaw remotely via the internet by sending crafted data to a dotnet application that is passed into Read7BitEncodedInt(), resulting in a denial of service when the output is used by ReadString(). • https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2020-1108 https://access.redhat.com/security/cve/CVE-2020-1108 https://bugzilla.redhat.com/show_bug.cgi?id=1827643 • CWE-190: Integer Overflow or Wraparound •
