TencentOS Server 4: perl-HTTP-Tiny (TSSA-2026:0610)

high Nessus Plugin ID 328387

Synopsis

The remote TencentOS Server 4 host is missing one or more security updates.

Description

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the TSSA-2026:0610 advisory.

 Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

 CVE-2026-7017:
 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.

Tenable has extracted the preceding description block directly from the Tencent Linux 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

Update the affected packages.
