The version of git installed on the remote host is prior to 2.38.1-1.77. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2022-1653 advisory.

    Git is an open source, scalable, distributed revision control system. Versions prior to 2.30.6, 2.31.5,     2.32.4, 2.33.5, 2.34.5, 2.35.5, 2.36.3, and 2.37.4 are subject to exposure of sensitive information to a     malicious actor. When performing a local clone (where the source and target of the clone are on the same     volume), Git copies the contents of the source's /objects directory into the destination by either     creating hardlinks to the source contents, or copying them (if hardlinks are disabled via --no-hardlinks).
    A malicious actor could convince a victim to clone a repository with a symbolic link pointing at sensitive     information on the victim's machine. This can be done either by having the victim clone a malicious     repository on the same machine, or having them clone a malicious repository embedded as a bare repository     via a submodule from any source, provided they clone with the --recurse-submodules option. Git does not     create symbolic links in the /objects directory. The problem has been patched in the versions published on     2022-10-18, and backported to v2.30.x. Potential workarounds: Avoid cloning untrusted repositories using     the --local optimization when on a shared machine, either by passing the --no-local option to git clone or     cloning from a URL that uses the file:// scheme. Alternatively, avoid cloning repositories from untrusted     sources with --recurse-submodules or run git config --global protocol.file.allow user. (CVE-2022-39253)

    Git is an open source, scalable, distributed revision control system. git shell is a restricted login     shell that can be used to implement Git's push/pull functionality via SSH. In versions prior to 2.30.6,     2.31.5, 2.32.4, 2.33.5, 2.34.5, 2.35.5, 2.36.3, and 2.37.4, the function that splits the command arguments     into an array improperly uses an int to represent the number of entries in the array, allowing a malicious     actor to intentionally overflow the return value, leading to arbitrary heap writes. Because the resulting     array is then passed to execv(), it is possible to leverage this attack to gain remote code execution on a     victim machine. Note that a victim must first allow access to git shell as a login shell in order to be     vulnerable to this attack. This problem is patched in versions 2.30.6, 2.31.5, 2.32.4, 2.33.5, 2.34.5,     2.35.5, 2.36.3, and 2.37.4 and users are advised to upgrade to the latest version. Disabling git shell     access via remote logins is a viable short-term workaround. (CVE-2022-39260)

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

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