Detailsinfo

A vulnerability, which was classified as critical, has been found in Rust up to 1.25.x. Affected by this issue is an unknown code block of the component Cargo. The manipulation with an unknown input leads to a code download vulnerability. Using CWE to declare the problem leads to CWE-494. The product downloads source code or an executable from a remote location and executes the code without sufficiently verifying the origin and integrity of the code. Impacted is confidentiality, integrity, and availability. CVE summarizes:

Cargo prior to Rust 1.26.0 may download the wrong dependency if your package.toml file uses the `package` configuration key. Usage of the `package` key to rename dependencies in `Cargo.toml` is ignored in Rust 1.25.0 and prior. When Rust 1.25.0 and prior is used Cargo may download the wrong dependency, which could be squatted on crates.io to be a malicious package. This not only affects manifests that you write locally yourself, but also manifests published to crates.io. If you published a crate, for example, that depends on `serde1` to crates.io then users who depend on you may also be vulnerable if they use Rust 1.25.0 and prior. Rust 1.0.0 through Rust 1.25.0 is affected by this advisory because Cargo will ignore the `package` key in manifests. Rust 1.26.0 through Rust 1.30.0 are not affected and typically will emit an error because the `package` key is unstable. Rust 1.31.0 and after are not affected because Cargo understands the `package` key. Users of the affected versions are strongly encouraged to update their compiler to the latest available one. Preventing this issue from happening requires updating your compiler to be either Rust 1.26.0 or newer. There will be no patch issued for Rust versions prior to 1.26.0. Users of Rust 1.19.0 to Rust 1.25.0 can instead apply linked patches to mitigate the issue.

The weakness was disclosed 09/30/2019 (GitHub Repository). The advisory is available at github.com. This vulnerability is handled as CVE-2019-16760 since 09/24/2019. The attack may be launched remotely. No form of authentication is required for exploitation. Successful exploitation requires user interaction by the victim. The technical details are unknown and an exploit is not available. This vulnerability is assigned to T1495 by the MITRE ATT&CK project.

Upgrading to version 1.26.0 eliminates this vulnerability.
