CVE-2015-4051 – Beckoff CX9020 CPU Model Remote Code Execution

https://notcve.org/view.php?id=CVE-2015-4051

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. Beckhoff IPC Diagnostics anterior a 1.8 no restringe correctamente el acceso a funciones en /config, lo que permite a atacantes remotos causar una denegación de servicio (reinicio o cierre), crear usuarios arbitrarios o posiblemente tener otro impacto no especificado a través de una solicitud manipulada, tal y como fue demostrado por una acción SOAP beckhoff.com:service:cxconfig:1#Write en /upnpisapi. Beckhoff IPC Diagnostics versions prior to 1.8 suffer from an authentication bypass vulnerability. • http://ftp.beckhoff.com/download/document/IndustPC/Advisory-2015-001.pdf http://packetstormsecurity.com/files/132168/Beckhoff-IPC-Diagnositcs-Authentication-Bypass.html http://packetstormsecurity.com/files/134071/Beckoff-CX9020-CPU-Model-Remote-Code-Execution.html http://seclists.org/fulldisclosure/2015/Jun/10 http://www.securityfocus.com/bid/75042 http://www.thesecurityfactory.be/permalink/beckhoff-authentication-bypass.html • CWE-284: Improper Access Control •
