FreeBSD : caddy -- multiple vulnerabilities (94f93681-6775-11f1-8044-002590af0794)

high Nessus Plugin ID 321073

Language:

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

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 94f93681-6775-11f1-8044-002590af0794 advisory.

Caddy project reports:
Caddy 2.11.4 contains multiple security fixes.
GitHub Security Advisory GHSA-qrp7-cvwr-j2c6 reports:
Windows-encoded backslashes in request paths could bypass path-scoped authorization rules before files are served by file_server.
GitHub Security Advisory GHSA-f59h-q822-g45g reports:
forward_auth copy_headers could fail to remove underscore aliases of copied identity headers before FastCGI header normalization, allowing identity or group header spoofing.
GitHub Security Advisory GHSA-vcc4-2c75-vc9v reports:
The stripHTML template function could fail to remove malformed HTML, potentially allowing client-side cross-site scripting if untrusted output is later rendered as HTML.

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

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

Solution

Update the affected packages.
