Remote Code Execution (RCE) in Yamaha synthesizers: an exploit in MIDI files & a hidden backdoor 🎹♫💉👨🏻💻🎉
Security researcher and musician Anna Antonenko, aka “porta,” shares her security research on the Yamaha PSR-E433: it looks like the device accepts special MIDI messages that allow commands to be executed. A hidden (or at least undocumented) backdoor inside Yamaha devices? :)
The author dumped the firmware via JTAG, reverse-engineered it, and found a hidden command shell with a hardcoded password “#0000”. Since the shell worked through MIDI system-exclusive messages, it could be triggered by a specially crafted MIDI file.
Quite an impressive and very interesting journey of security research that includes hardware, firmware, and music (MIDI). I wonder if you have a hobby you can hack?
