"The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple
vulnerabilities as referenced in the 11e36890-d28c-11ec-a06f-d4c9ef517024 advisory.

  - Using its HSTS support, curl can be instructed to use HTTPS directly insteadof using an insecure clear-
    text HTTP step even when HTTP is provided in theURL. This mechanism could be bypassed if the host name in
    the given URL used atrailing dot while not using one when it built the HSTS cache. Or the otherway around
    - by having the trailing dot in the HSTS cache and *not* using thetrailing dot in the URL.
    (CVE-2022-30115)

  - A use of incorrectly resolved name vulnerability fixed in 7.83.1 might remove the wrong file when `--no-
    clobber` is used together with `--remove-on-error`. (CVE-2022-27778)

  - libcurl wrongly allows cookies to be set for Top Level Domains (TLDs) if thehost name is provided with a
    trailing dot.curl can be told to receive and send cookies. curl's cookie engine can bebuilt with or
    without [Public Suffix List](https://publicsuffix.org/)awareness. If PSL support not provided, a more
    rudimentary check exists to atleast prevent cookies from being set on TLDs. This check was broken if
    thehost name in the URL uses a trailing dot.This can allow arbitrary sites to set cookies that then would
    get sent to adifferent and unrelated site or domain. (CVE-2022-27779)

  - The curl URL parser wrongly accepts percent-encoded URL separators like '/'when decoding the host name
    part of a URL, making it a *different* URL usingthe wrong host name when it is later retrieved.For
    example, a URL like `http://example.com%2F127.0.0.1/`, would be allowed bythe parser and get transposed
    into `http://example.com/127.0.0.1/`. This flawcan be used to circumvent filters, checks and more.
    (CVE-2022-27780)

  - libcurl provides the `CURLOPT_CERTINFO` option to allow applications torequest details to be returned
    about a server's certificate chain.Due to an erroneous function, a malicious server could make libcurl
    built withNSS get stuck in a never-ending busy-loop when trying to retrieve thatinformation.
    (CVE-2022-27781)

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