This causes swift-nio-http2 to commit to a large amount of expensive work which it then throws away, including creating entirely new `Channel`s to serve the traffic. This can easily overwhelm an `EventLoop` and prevent it from making forward progress. swift-nio-http2 1.28 contains a remediation for this issue that applies reset counter using a sliding window. This constrains the number of stream resets that may occur in a given window of time. Clients violating this limit will have their connections torn down. This allows clients to continue to cancel streams for legitimate reasons, while constraining malicious actors. #### Severity - CVSS Score: 5.3 / 10 (Medium) - Vector String: `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L` #### References -

While the total number of requests is bounded by the http2.Server.MaxConcurrentStreams setting, resetting an in-progress request allows the attacker to create a new request while the existing one is still executing. With the fix applied, HTTP/2 servers now bound the number of simultaneously executing handler goroutines to the stream concurrency limit (MaxConcurrentStreams). New requests arriving when at the limit (which can only happen after the client has reset an existing, in-flight request) will be queued until a handler exits. If the request queue grows too large, the server will terminate the connection. This issue is also fixed in golang.org/x/net/http2 for users manually configuring HTTP/2. The default stream concurrency limit is 250 streams (requests) per HTTP/2 connection. This value may be adjusted using the golang.org/x/net/http2 package; see the Server.MaxConcurrentStreams setting and the ConfigureServer function. #### Severity Moderate #### References - [https://nvd.nist.gov/vuln/detail/CVE-2023-39325](https://nvd.nist.gov/vuln/detail/CVE-2023-39325) - [https://github.com/golang/go/issues/63417](https://togithub.com/golang/go/issues/63417) - [https://go.dev/cl/534215](https://go.dev/cl/534215) - [https://go.dev/cl/534235](https://go.dev/cl/534235) - [https://go.dev/issue/63417](https://go.dev/issue/63417) - [https://groups.google.com/g/golang-announce/c/iNNxDTCjZvo/m/UDd7VKQuAAAJ](https://groups.google.com/g/golang-announce/c/iNNxDTCjZvo/m/UDd7VKQuAAAJ) - [https://pkg.go.dev/vuln/GO-2023-2102](https://pkg.go.dev/vuln/GO-2023-2102) - [golang.org/x/net](golang.org/x/net) This data is provided by [OSV](https://osv.dev/vulnerability/GHSA-4374-p667-p6c8) and the [GitHub Advisory Database](https://togithub.com/github/advisory-database) ([CC-BY 4.0](https://togithub.com/github/advisory-database/blob/main/LICENSE.md)). </details> --- ### HTTP/2 rapid reset can cause excessive work in net/http [CVE-2023-39325](https://nvd.nist.gov/vuln/detail/CVE-2023-39325) / [CVE-2023-44487](https://nvd.nist.gov/vuln/detail/CVE-2023-44487) / [GHSA-4374-p667-p6c8](https://togithub.com/advisories/GHSA-4374-p667-p6c8) / [GO-2023-2102](https://pkg.go.dev/vuln/GO-2023-2102) <details> <summary>More information</summary> #### Details A malicious HTTP/2 client which rapidly creates requests and immediately resets them can cause excessive server resource consumption.
