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.

The remote host is affected by the vulnerability described in GLSA-202409-07 (Rust: Multiple Vulnerabilities)

    Multiple vulnerabilities have been discovered in Rust. Please review the CVE identifiers referenced below     for details.

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

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-109 advisory.

    2024-02-15: CVE-2022-36113 was added to this advisory.

    2024-02-15: CVE-2022-36114 was added to this advisory.

    Cargo is a package manager for the rust programming language. After a package is downloaded, Cargo     extracts its source code in the ~/.cargo folder on disk, making it available to the Rust projects it     builds. To record when an extraction is successful, Cargo writes ok to the .cargo-ok file at the root of     the extracted source code once it extracted all the files. It was discovered that Cargo allowed packages     to contain a .cargo-ok symbolic link, which Cargo would extract. Then, when Cargo attempted to write ok     into .cargo-ok, it would actually replace the first two bytes of the file the symlink pointed to with ok.
    This would allow an attacker to corrupt one file onthe machine using Cargo to extract the package. Note     that by design Cargo allows code execution at build time, due to build scripts and procedural macros. The     vulnerabilities in this advisory allow performing a subset of the possible damage in a harder to track     down way. Your dependencies must still be trusted if you want to be protected from attacks, as its     possible to perform the same attacks with build scripts and procedural macros. The vulnerabilityis present     in all versions of Cargo. Rust 1.64, to be released on September 22nd, will include a fix for it. Since     the vulnerability is just a more limited way to accomplish what a malicious build scripts or procedural     macros cando, we decided not to publish Rust point releases backporting the security fix. Patch files are     available for Rust 1.63.0 are available in the wg-security-response repository for people building their     own toolchain. Mitigations Werecommend users of alternate registries to exercise care in which package     they download, by only including trusted dependencies in their projects. Please note that even with these     vulnerabilities fixed, by design Cargo allows arbitrary code execution at build time thanks to build     scripts and procedural macros: a malicious dependency will be able to cause damage regardless of these     vulnerabilities. crates.io implemented server-side checks to reject these kinds of packages years ago, and     there are no packages on crates.io exploiting these vulnerabilities. crates.io users still need to     exercise care in choosing their dependencies though, as remote code execution is allowed by designthere as     well. (CVE-2022-36113)

    Cargo is a package manager for the rust programming language. It was discovered that Cargo did not limit     the amount of data extracted from compressed archives. An attacker could upload to an alternate registry a     specially crafted package that extracts way more data than its size (also known as a zip bomb),     exhausting the disk space on the machine using Cargo to download the package. Note that by design Cargo     allows code execution at buildtime, due to build scripts and procedural macros. The vulnerabilities in     this advisory allow performing a subset of the possible damage in a harder to track down way. Your     dependencies must still be trusted if you want to be protected from attacks, as its possible to perform     the same attacks with build scripts and procedural macros.
