Vulnerability from variot
A vulnerability has been identified in SINEMA Remote Connect Server (All versions < V2.0). Due to insufficient checking of user permissions, an attacker may access URLs that require special authorization. An attacker must have access to a low privileged account in order to exploit the vulnerability. SINEMA Remote Connect Server Contains vulnerabilities related to authorization, permissions, and access control.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Siemens is a leading global technology company that provides solutions to customers in the areas of power generation and transmission and distribution, infrastructure, industrial automation, drive and software with innovation in electrification, automation and digital. Siemens SINEMA has an unauthorized access vulnerability that an attacker can use to gain unauthorized access and perform unauthorized actions. This may aid in further attacks. An attacker could use the vulnerability to compromise confidentiality, integrity and availability of the affected system. At the time of advisory publication no public exploitation of this security vulnerability was known. The platform supports efficient and secure remote access to machines and equipment distributed around the world, as well as secure management of VPN tunnels between control centers, service engineers and installed equipment. The vulnerability stems from the lack of effective permissions and access control measures in network systems or products
