TITLE

Microsoft ASP.NET Core Input validation vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2017-003293

DESCRIPTION

A denial of service vulnerability exists when the ASP.NET Core fails to properly validate web requests. NOTE: Microsoft has not commented on third-party claims that the issue is that the TextEncoder.EncodeCore function in the System.Text.Encodings.Web package in ASP.NET Core Mvc before 1.0.4 and 1.1.x before 1.1.3 allows remote attackers to cause a denial of service by leveraging failure to properly calculate the length of 4-byte characters in the Unicode Non-Character range. Microsoft ASP.NET Core Contains an input validation vulnerability.Information may be tampered with. The framework is used to build cloud-based applications such as web applications, IoT applications, and mobile backends. An attacker can use this vulnerability to cause a denial of service
