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 33ba2241-c68e-11ee-9ef3-001999f8d30b advisory.
vendor/composer/InstalledVersions.php
and vendor/composer/installed.php
do not include untrusted code.sh rm vendor/composer/installed.php vendor/composer/InstalledVersions.php composer install --no-scripts --no-plugins
(CVE-2024-24821)Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.

"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 33ba2241-c68e-11ee-9ef3-001999f8d30b advisory.
- Composer is a dependency Manager for the PHP language. In affected versions several files within the local
working directory are included during the invocation of Composer and in the context of the executing user.
As such, under certain conditions arbitrary code execution may lead to local privilege escalation, provide
lateral user movement or malicious code execution when Composer is invoked within a directory with
tampered files. All Composer CLI commands are affected, including composer.phar's self-update. The
following scenarios are of high risk: Composer being run with sudo, Pipelines which may execute Composer
on untrusted projects, Shared environments with developers who run Composer individually on the same
project. This vulnerability has been addressed in versions 2.7.0 and 2.2.23. It is advised that the
patched versions are applied at the earliest convenience. Where not possible, the following should be
addressed: Remove all sudo composer privileges for all users to mitigate root privilege escalation, and
avoid running Composer within an untrusted directory, or if needed, verify that the contents of
`vendor/composer/InstalledVersions.php` and `vendor/composer/installed.php` do not include untrusted code.
A reset can also be done on these files by the following:```sh rm vendor/composer/installed.php
vendor/composer/InstalledVersions.php composer install --no-scripts --no-plugins ``` (CVE-2024-24821)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
