TITLE

Siemens BACnet Field Panels Security Bypass Vulnerability

Trust: 0.8

sources: IVD: 67f856e2-a482-4c06-91ff-c65f6e4dfd02 // CNVD: CNVD-2017-29973

DESCRIPTION

A vulnerability has been identified in Siemens APOGEE PXC and TALON TC BACnet Automation Controllers in all versions <V3.5. An attacker with network access to the integrated web server (80/tcp and 443/tcp) could bypass the authentication and download sensitive information from the device. BACnet (Building Automation Control Network) is a data communication protocol for building automation and control networks. Multiple Siemens Products are prone to an authentication-bypass and directory-traversal vulnerabilities. Attackers may exploit these issues to gain unauthorized access to restricted content by bypassing intended security restrictions or to obtain sensitive information that may aid in launching further attacks
