What is CVE-2022-29117?

CVE-2022-29117 is a high-severity uncontrolled resource consumption vulnerability in Microsoft.AspNetCore.App.Runtime.win-x64 (nuget), affecting versions >= 3.0.0, <= 3.1.24. It is fixed in 3.1.25, 5.0.17, 6.0.5, 4.2.2. Crafted input forces the application to consume excessive CPU, memory, or other resources, degrading or denying service.

How severe is CVE-2022-29117?

CVE-2022-29117 has a CVSS score of 7.5 (High). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.

Which packages are affected by CVE-2022-29117?

Microsoft.AspNetCore.App.Runtime.win-x64 (nuget) versions >= 3.0.0, = 3.0.0, = 3.0.0, = 3.0.0, = 3.0.0, = 3.0.0, = 3.0.0, = 3.0.0, = 3.0.0, = 3.0.0, = 3.0.0, = 6.0.0, < 6.0.5.

Is there a fix for CVE-2022-29117?

Yes. CVE-2022-29117 is fixed in 3.1.25, 5.0.17, 6.0.5, 4.2.2. Upgrade to this version or later.

Is CVE-2022-29117 exploitable, and should I be worried?

Whether CVE-2022-29117 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

What actually determines whether CVE-2022-29117 is exploitable, and how bad it is?

Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.

Impact

Crafted input forces the application to consume excessive CPU, memory, or other resources, degrading or denying service. Typical impact: denial of service.

CVE-2022-29117 has a CVSS score of 7.5 (High). The vector is network-reachable, no privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (3.1.25, 5.0.17, 6.0.5, 4.2.2); upgrading removes the vulnerable code path.

Kodem intelligence

Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.

Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Remediation advice

If you're using .NET Core 6.0, you should download and install Runtime 6.0.5 or SDK 6.0.105 (for Visual Studio 2022 v17.0) or SDK 6.0.203 (for Visual Studio 2022 v17.1) from https://dotnet.microsoft.com/download/dotnet-core/6.0.
If you're using .NET 5.0, you should download and install Runtime 5.0.17 or SDK 5.0.214 (for Visual Studio 2019 v16.9) or SDK 5.0.408 (for Visual Studio 2011 v16.11) from https://dotnet.microsoft.com/download/dotnet-core/5.0.
If you're using .NET Core 3.1, you should download and install Runtime 3.1.25 or SDK 3.1.419 (for Visual Studio 2019 v16.9 or Visual Studio 2011 16.11 or Visual Studio 2022 17.0 or Visual Studio 2022 17.1 ) from https://dotnet.microsoft.com/download/dotnet-core/3.1.
