Auth bypass in Electrolink Compact Dab Transmitter
CVE-2024-1491
The devices allow 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.
