      <title>CVE-2024-24791 — Denial of service due to improper 100-continue handling in net/http</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2024-24791</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Go standard library net/http, go_standard_library net\/http&lt;/p&gt;
&lt;p&gt;The net/http HTTP/1.1 client mishandled the case where a server responds to a request with an &amp;#34;Expect: 100-continue&amp;#34; header with a non-informational (200 or higher) status. 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 &amp;#34;Expect: 100-continue&amp;#34; 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.&lt;/p&gt;</description>
