TEM Opera Plus FM Family Transmitter 35.45 Remote Code Execution
TEM Opera Plus FM Family Transmitter 35.45 Remote Code Execution Vendor: Telecomunicazioni Elettro Milano (TEM) S.r.l. Product web page: https://www.tem-italy.it Affected version: Software version: 35.45 Webserver version: 1.7 Summary: This new line of Opera plus FM Transmitters combines very high efficiency, high reliability and low energy consumption in compact solutions. They have innovative functions and features that can eliminate the costs required by additional equipment: automatic exchange of audio sources, built-in stereo encoder, integrated RDS encoder, parallel I/O card, connectivity through GSM telemetry and/or TCP IP / SNMP / SMTP Webserver. Desc: The device allows access to an unprotected endpoint that allows MPFS File System binary image upload without authentication. The MPFS2 file system module provides a light-weight read-only file system that can be stored in external EEPROM, external serial Flash, or internal Flash program memory. This file system serves as the basis for the HTTP2 web server module, but is also used by the SNMP module and is available to other applications that require basic read-only storage capabilities. This can be exploited to overwrite the flash program memory that holds the web server's main interfaces and execute arbitrary code.
