"The remote Alibaba Cloud Linux 3 host has packages installed that are affected by a vulnerability as referenced in the
ALINUX3-SA-2024:0226 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2024-24791:
    The net/http HTTP/1.1 client mishandled the case where a server responds to a request with an Expect:
    100-continue 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 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.

Tenable has extracted the preceding description block directly from the Alibaba Cloud Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
