var-201707-1137
Vulnerability from variot
An Improper Authentication issue was discovered in Siemens SIMATIC CP 44x-1 RNA, all versions prior to 1.4.1. An unauthenticated remote attacker may be able to perform administrative actions on the Communication Process (CP) of the RNA series module, if network access to Port 102/TCP is available and the configuration file for the CP is stored on the RNA's CPU. The SiemensSIMATICCP44x-1RNA is a communications processor that integrates security functions such as firewall, VPN, security protocol, data encryption, etc., providing network connectivity and secure communication for the s7-1500 controller. An unauthorized operating vulnerability exists in the pre-1.4.1 version of the Siemens SIMATICCP44x-1RNA module. Siemens SIMATIC CP 44x-1 Redundant is prone to an authentication-bypass vulnerability. An attacker can exploit this issue to bypass the authentication mechanism and perform unauthorized actions. This may aid in further attacks
