"The version of curl installed on the remote host is prior to 7.83.0. It is, therefore, affected by multiple
vulnerabilities as referenced in the SSA:2022-117-01 advisory.

  - 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-2022-27776)

  - 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-2022-22576)

  - 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-2022-27774)

  - An information disclosure vulnerability exists in curl 7.65.0 to 7.82.0 are vulnerable that by using an
    IPv6 address that was in the connection pool but with a different zone id it could reuse a connection
    instead. (CVE-2022-27775)

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