CVE-2017-16718 (GCVE-0-2017-16718)

Vulnerability from cvelistv5 – Published: 2018-06-27 19:00 – Updated: 2024-09-16 17:28

Summary

Beckhoff TwinCAT 3 supports communication over ADS. ADS is a protocol for industrial automation in protected environments. This protocol uses user configured routes, that can be edited remotely via ADS. This special command supports encrypted authentication with username/password. The encryption uses a fixed key, that could be extracted by an attacker. Precondition of the exploitation of this weakness is network access at the moment a route is added.

Severity ?
