TITLE

Beckhoff Embedded PC Images And automation device specifications TwinCAT Vulnerabilities that can gain access to components

Trust: 0.8

sources: JVNDB: JVNDB-2014-008182

DESCRIPTION

Beckhoff Embedded PC images before 2014-10-22 and Automation Device Specification (ADS) TwinCAT components do not restrict the number of authentication attempts, which makes it easier for remote attackers to obtain access via a brute-force attack. Supplementary information : CWE Vulnerability type by CWE-254: Security Features ( Security function ) Has been identified. http://cwe.mitre.org/data/definitions/254.htmlRound robin by a third party (brute-force) Access may be gained through an attack. Beckhoff Embedded PC Images is an industrial control system that is installed in the control cabinet and can be functionally configured. A remote attacker can exploit the vulnerability to gain access by implementing a brute force attack. Multiple Beckhoff Products are prone to multiple security-bypass vulnerabilities. Successfully exploiting these issues may allow attackers to perform unauthorized actions. This may lead to other attacks
