"It is, therefore, affected by a vulnerability as referenced in the ALAS2022-2023-278 advisory.

  - Cargo is a Rust package manager. The Rust Security Response WG was notified that Cargo did not perform SSH
    host key verification when cloning indexes and dependencies via SSH. An attacker could exploit this to
    perform man-in-the-middle (MITM) attacks. This vulnerability has been assigned CVE-2022-46176. All Rust
    versions containing Cargo before 1.66.1 are vulnerable. Note that even if you don't explicitly use SSH for
    alternate registry indexes or crate dependencies, you might be affected by this vulnerability if you have
    configured git to replace HTTPS connections to GitHub with SSH (through git's [`url.<base>.insteadOf`][1]
    setting), as that'd cause you to clone the crates.io index through SSH. Rust 1.66.1 will ensure Cargo
    checks the SSH host key and abort the connection if the server's public key is not already trusted. We
    recommend everyone to upgrade as soon as possible. (CVE-2022-46176)

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