A vulnerability has been identified in Siemens APOGEE PXC and TALON TC BACnet Automation Controllers in all versions <V3.5. A directory traversal vulnerability could allow a remote attacker with network access to the integrated web server (80/tcp and 443/tcp) to obtain information on the structure of the file system of the affected devices.
The product places sensitive information into files or directories that are accessible to actors who are allowed to have access to the files, but not to the sensitive information.
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
