Detailsinfo

A vulnerability classified as critical has been found in Python TUF up to 0.11 (Programming Language Software). This affects an unknown part. The manipulation with an unknown input leads to a authorization vulnerability. CWE is classifying the issue as CWE-863. The product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check. This allows attackers to bypass intended access restrictions. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Python TUF (The Update Framework) reference implementation before version 0.12 it will incorrectly trust a previously downloaded root metadata file which failed verification at download time. This allows an attacker who is able to serve multiple new versions of root metadata (i.e. by a person-in-the-middle attack) culminating in a version which has not been correctly signed to control the trust chain for future updates. This is fixed in version 0.12 and newer.

The weakness was presented 09/09/2020 (GitHub Repository). The advisory is shared at github.com. This vulnerability is uniquely identified as CVE-2020-15163 since 06/25/2020. It is possible to initiate the attack remotely. A authentication is necessary for exploitation. It demands that the victim is doing some kind of user interaction. Neither technical details nor an exploit are publicly available.
