The version of git installed on the remote host is prior to 2.23.4-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2021-1621 advisory.

    Git is an open-source distributed revision control system. In affected versions of Git a specially crafted     repository that contains symbolic links as well as files using a clean/smudge filter such as Git LFS, may     cause just-checked out script to be executed while cloning onto a case-insensitive file system such as     NTFS, HFS+ or APFS (i.e. the default file systems on Windows and macOS). Note that clean/smudge filters     have to be configured for that. Git for Windows configures Git LFS by default, and is therefore     vulnerable. The problem has been patched in the versions published on Tuesday, March 9th, 2021. As a     workaound, if symbolic link support is disabled in Git (e.g. via `git config --global core.symlinks     false`), the described attack won't work. Likewise, if no clean/smudge filters such as Git LFS are     configured globally (i.e. _before_ cloning), the attack is foiled. As always, it is best to avoid cloning     repositories from untrusted sources. The earliest impacted version is 2.14.2. The fix versions are:
    2.30.1, 2.29.3, 2.28.1, 2.27.1, 2.26.3, 2.25.5, 2.24.4, 2.23.4, 2.22.5, 2.21.4, 2.20.5, 2.19.6, 2.18.5,     2.17.62.17.6. (CVE-2021-21300)

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

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