TITLE

Beckhoff IPC Diagnostics Service disruption in (DoS) Vulnerabilities

Trust: 0.8

sources: JVNDB: JVNDB-2015-002962

DESCRIPTION

Beckhoff IPC Diagnostics before 1.8 does not properly restrict access to functions in /config, which allows remote attackers to cause a denial of service (reboot or shutdown), create arbitrary users, or possibly have unspecified other impact via a crafted request, as demonstrated by a beckhoff.com:service:cxconfig:1#Write SOAP action to /upnpisapi. Supplementary information : CWE Vulnerability type by CWE-284: Improper Access Control ( Inappropriate access control ) Has been identified. http://cwe.mitre.org/data/definitions/284.htmlService disruption through a crafted request by a third party ( Reboot or shutdown ) It can be unspecified, such as being in a state or creating an arbitrary user. Beckhoff IPC Diagnostics is a set of support software pre-installed in all Beckhoff IPC/PLC (Programmable Logic Controllers) running on the Microsoft Windows operating system. Beckhoff IPC diagnostics is prone to multiple authentication-bypass vulnerabilities. An attacker can exploit these issues to bypass the authentication mechanism and perform unauthorized actions. This may aid in further attacks
