fish is a command line shell. fish version 3.1.0 through version 3.3.1 is vulnerable to arbitrary code execution. git repositories can contain per-repository configuration that change the behavior of git, including running arbitrary commands. When using the default configuration of fish, changing to a directory automatically runs `git` commands in order to display information about the current repository in the prompt. If an attacker can convince a user to change their current directory into one controlled by the attacker, such as on a shared file system or extracted archive, fish will run arbitrary commands under the attacker's control. This problem has been fixed in fish 3.4.0. Note that running git in these directories, including using the git tab completion, remains a potential trigger for this issue. As a workaround, remove the `fish_git_prompt` function from the prompt.

The remote Ubuntu 20.04 ESM / 22.04 ESM host has packages installed that are affected by a vulnerability as referenced in the USN-5367-1 advisory.

    Justin Steven discovered that fish was not properly filtering local git configuration directives when     running background git commands. A remote unauthenticated attacker could possibly use this issue to     execute arbitrary code.

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

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