Detailsinfo

A vulnerability has been found in tough Library up to 0.7.0 (Software Library) and classified as critical. Affected by this vulnerability is an unknown code of the component Signature Validation. The manipulation with an unknown input leads to a signature verification vulnerability. The CWE definition for the vulnerability is CWE-347. The product does not verify, or incorrectly verifies, the cryptographic signature for data. As an impact it is known to affect integrity. The summary by CVE is:

The tough library (Rust/crates.io) prior to version 0.7.1 does not properly verify the threshold of cryptographic signatures. It allows an attacker to duplicate a valid signature in order to circumvent TUF requiring a minimum threshold of unique signatures before the metadata is considered valid. A fix is available in version 0.7.1. CVE-2020-6174 is assigned to the same vulnerability in the TUF reference implementation.

The weakness was shared 07/09/2020 (GitHub Repository). It is possible to read the advisory at github.com. This vulnerability is known as CVE-2020-15093 since 06/25/2020. The attack can be launched remotely. The exploitation doesn't need any form of authentication. The technical details are unknown and an exploit is not publicly available.

Upgrading to version 0.7.1 eliminates this vulnerability.
