"The remote NewStart CGSL host, running version MAIN 7.02, has git packages installed that are affected by a
vulnerability:

  - Git is a fast, scalable, distributed revision control system with an unusually rich command set that
    provides both high-level operations and full access to internals. When reading a config value, Git strips
    any trailing carriage return and line feed (CRLF). When writing a config entry, values with a trailing CR
    are not quoted, causing the CR to be lost when the config is later read. When initializing a submodule, if
    the submodule path contains a trailing CR, the altered path is read resulting in the submodule being
    checked out to an incorrect location. If a symlink exists that points the altered path to the submodule
    hooks directory, and the submodule contains an executable post-checkout hook, the script may be
    unintentionally executed after checkout. This vulnerability is fixed in v2.43.7, v2.44.4, v2.45.4,
    v2.46.4, v2.47.3, v2.48.2, v2.49.1, and v2.50.1. (CVE-2025-48384)

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