The Xbox One scene might finally be starting to get a little interesting. XVMM has released a privilege escalation exploit for Xbox One consoles running in dev mode.
Essentially this allows you to breakout the user land sandbox and gain Administrator access. Currently this will allow you to dump the nand using the XRF tool, however it might allow for some other interesting things to happen.
Either way its nice to see a little Xbox One activity after all these years. Microsoft will probably patch this exploit pretty soon however.
