CLI Baseline B05 - credentials exposed in the process table

cli-baseline-b05-argv-secrets is a high severity check in the cli-baseline category, written in shell. Its source is templates/cli-baseline/cli-baseline-b05-argv-secrets.sh in cert-x-gen-templates.

What it checks

Invokes the target with a credential-shaped option and reads the process table from a second process during the run. If the value reaches a child process’s argv, every other user on the host can read it.

Conventions of the repository, not fields the engine reads

@target_kinds and @oracles are documented in the templates repository’s contribution guide, and cxg’s annotation parser does not carry them into a template’s metadata. Nothing at scan time selects on them. The annotation header schema is every field the parser does read.

The file declares @allow_nonzero_exit as well. Those are not tabled above; read the source for what they carry.

Run it

To see what the copy on your machine says about itself, and to confirm it is installed at all:

cxg template info cli-baseline-b05-argv-secrets

The id it prints is the one to pass anywhere a template is selected. See cxg template for the rest of the subcommand, Scan a target for running a scan, and A match is not a finding for how to read what comes back.
