.NET and Visual Studio Denial of Service Vulnerability
CVE-2022-29145
Description
.NET and Visual Studio Denial of Service Vulnerability
AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
.NET and Visual Studio are vulnerable to a denial of service when a malicious client sends specially crafted HTML forms.
Vulnerability
A denial of service vulnerability exists in .NET 6.0, .NET 5.0, and .NET Core 3.1 where a malicious client can cause a denial of service when HTML forms are parsed [2]. Affected versions include .NET 6.0.4 or earlier, .NET 5.0.16 or earlier, and .NET Core 3.1.24 or earlier [2]. The vulnerability also affects Visual Studio as stated in the official description [1].
Exploitation
An unauthenticated attacker can send a malicious request to a vulnerable .NET application that parses HTML forms, causing the application to crash or become unresponsive [2]. No authentication or special privileges are required; the attacker only needs network access to the target application.
Impact
Successful exploitation leads to a denial of service condition, rendering the affected .NET or Visual Studio application unavailable. This impacts the availability of the application, but does not affect confidentiality or integrity [1][2].
Mitigation
Microsoft released patched versions: .NET 6.0.5, .NET 5.0.17, and .NET Core 3.1.25 [2]. Developers should update their applications to these versions or later [2]. No workaround is provided; updating is the only mitigation.
