This mishandling could leave a client connection in an invalid state, where the next request sent on the connection will fail. An attacker sending a request to a net/http/httputil.ReverseProxy proxy can exploit this mishandling to cause a denial of service by sending \"Expect: 100-continue\" requests which elicit a non-informational response from the backend. Each such request leaves the proxy with an invalid connection, and causes one subsequent request using that connection to fail.","affected":[{"package":{"name":"golang","ecosystem":"Bitnami","purl":"pkg:bitnami/golang"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"1.21.12"},{"introduced":"1.22.0-0"},{"fixed":"1.22.5"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/golang/BIT-golang-2024-24791.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}],"references":[{"type":"WEB","url":"https://go.dev/cl/591255"},{"type":"WEB","url":"https://go.dev/issue/67555"},{"type":"WEB","url":"https://groups.google.com/g/golang-dev/c/t0rK-qHBqzY/m/6MMoAZkMAgAJ"},{"type":"WEB","url":"https://pkg.go.dev/vuln/GO-2024-2963"},{"type":"WEB","url":"https://security.netapp.com/advisory/ntap-20241004-0004/"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-24791"}],"database_specific":{"cpes":["cpe:2.3:a:golang:go:*:*:*:*:*:*:*:*"],"severity":"High"}}
