Amazon Linux 2023 : perl-HTTP-Tiny, perl-HTTP-Tiny-tests (ALAS2023-2026-3194)

high Nessus Plugin ID 365201

Synopsis

The remote Amazon Linux 2023 host is missing a security update.

Description

It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2026-3194 advisory.

HTTP::Tiny versions before 0.095 for Perl forward credential headers to cross-origin redirect targets.

When the server returns a 3xx redirect, `_maybe_redirect` follows the `Location:` header and `_prepare_headers_and_cb` re-merges the caller's `headers` argument into the new request, without checking whether the redirect target shares an origin with the original URL. Caller-supplied `Authorization`, `Cookie` and `Proxy-Authorization` headers are therefore re-sent to whatever host the redirect names, across scheme, host or port boundaries, and including `https` to `http` downgrades that expose them in plaintext on the wire.

The HTTP::Tiny POD note that Authorization headers will not be included in a redirected request applied only to the URL-userinfo Basic-auth path, not to headers passed explicitly by the caller. (CVE-2026-7017)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

Solution

Run 'dnf update perl-HTTP-Tiny --releasever 2023.12.20261012' or or 'dnf update --advisory ALAS2023-2026-3194 --releasever 2023.12.20261012' to update your system.
