CVSS: 7.5EPSS: 0%CPEs: 3EXPL: 0CVE-2020-1161 – dotnet: Denial of service due to infinite loop
https://notcve.org/view.php?id=CVE-2020-1161
A denial of service vulnerability exists when ASP.NET Core improperly handles web requests, aka 'ASP.NET Core Denial of Service Vulnerability'. Existe una vulnerabilidad denegación de servicio cuando ASP.NET Core maneja inapropiadamente las peticiones web, también se conoce como "ASP.NET Core Denial of Service Vulnerability". An infinite loop was found in the HTTP Routing component of Microsoft.AspNetCore.App, which could be exploited by a remote, unauthenticated attacker. This flaw allows an attacker without special privileges to send crafted requests to a machine running an ASP.NET Core application, triggering the infinite loop and causing a denial of service in that application, for example, a web server. • https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2020-1161 https://access.redhat.com/security/cve/CVE-2020-1161 https://bugzilla.redhat.com/show_bug.cgi?id=1827645 • CWE-400: Uncontrolled Resource Consumption •
CVSS: 7.5EPSS: 0%CPEs: 132EXPL: 0CVE-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 •
