"The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced
in the ALINUX3-SA-2022:0142 advisory.

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

    CVE-2022-22576:
    An improper authentication vulnerability exists in curl 7.33.0 to and including 7.82.0 which might allow
    reuse OAUTH2-authenticated connections without properly making sure that the connection was authenticated
    with the same credentials as set for this transfer. This affects SASL-enabled protocols: SMPTP(S),
    IMAP(S), POP3(S) and LDAP(S) (openldap only).

    CVE-2022-27774:
    An insufficiently protected credentials vulnerability exists in curl 4.9 to and include curl 7.82.0 are
    affected that could allow an attacker to extract credentials when follows HTTP(S) redirects is used with
    authentication could leak credentials to other services that exist on different protocols or port numbers.

    CVE-2022-27776:
    A insufficiently protected credentials vulnerability in fixed in curl 7.83.0 might leak authentication or
    cookie header data on HTTP redirects to the same host but another port number.

    CVE-2022-27782:
    libcurl would reuse a previously created connection even when a TLS or SSHrelated option had been changed
    that should have prohibited reuse.libcurl keeps previously used connections in a connection pool for
    subsequenttransfers to reuse if one of them matches the setup. However, several TLS andSSH settings were
    left out from the configuration match checks, making themmatch too easily.

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

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