The remote AlmaLinux 9 host has packages installed that are affected by a vulnerability as referenced in the ALSA-2024:1129 advisory.

when the URL used a lower case hostname curl.co.uk
, even though co.uk
is listed as a PSL domain. (CVE-2023-46218)Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.

- This flaw allows a malicious HTTP server to set super cookies in curl that are then passed back to more
origins than what is otherwise allowed or possible. This allows a site to set cookies that then would get
sent to different and unrelated sites and domains. It could do this by exploiting a mixed case flaw in
curl's function that verifies a given cookie domain against the Public Suffix List (PSL). For example a
cookie could be set with `domain=co.UK` when the URL used a lower case hostname `curl.co.uk`, even though
`co.uk` is listed as a PSL domain. (CVE-2023-46218)
