FreeBSD : Routinator -- CWE-22 Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') (e7be3859-6a58-11f1-bf61-3c7c3fba4204)

high Nessus Plugin ID 321614

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 a vulnerability as referenced in the e7be3859-6a58-11f1-bf61-3c7c3fba4204 advisory.

 https://www.nlnetlabs.nl/downloads/routinator/CVE-2026-49233.txt reports:
 Routinator does not properly check the module component of rsync URIs, which are used to create the file system paths for the Routinator cache. This allows for path traversal by having a module name containing .., potentially providing an attacker access to the entire Routinator rsync cache.
 Thanks to X41 D-Sec GmbH for reporting the vulnerability.

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