NASL family Windows NASL id SMB_NT_MS18_JAN_DOTNET_CORE.NASL description The remote Windows host has an installation of .NET Core with a version less than 2.0.5. Therefore, the host is affected by multiple vulnerabilities : - A security feature bypass in X509 Certificate Validation allows an attacker to present a certificate that is marked as invalid for a specific use, but a component uses it for that purpose. (CVE-2018-0786) - A denial of service vulnerability exists due to improper processing of XML documents. An attacker who successfully exploited this vulnerability could cause a denial of service against a .NET application. A remote unauthenticated attacker could exploit this vulnerability by issuing specially crafted requests to a .NET Core application.

It is, therefore, affected by the following vulnerabilities: - A Denial of Service vulnerability exists when .NET, and .NET core, improperly process XML documents. An attacker who successfully exploited this vulnerability could cause a denial of service against a .NET application. A remote unauthenticated attacker could exploit this vulnerability by issuing specially crafted requests to a .NET(or .NET core) application. (CVE-2018-0764) - A security feature bypass vulnerability exists when Microsoft .NET Framework (and .NET Core) components do not completely validate certificates. An attacker could present a certificate that is marked invalid for a specific use, but the component uses it for that purpose. This action disregards the Enhanced Key Usage taggings.
