CVE-2018-20785

Secure boot bypass and memory extraction can be achieved on Neato Botvac Connected 2.2.0 devices. During startup, the AM335x secure boot feature decrypts and executes firmware. Secure boot can be bypassed by starting with certain commands to the USB serial port. Although a power cycle occurs, thi...

CVE-2018-20785

CVE-2018-20785 affects Neato Botvac Connected 2.2.0. The AM335x secure boot can be bypassed by issuing certain commands to the USB serial port during startup, allowing execution of an unsigned QNX IFS image via a boot menu (XMODEM). A power cycle does not fully reset the chip, leaving memory cont...

CVE-2018-15370

A vulnerability in Cisco IOS ROM Monitor ROMMON Software for Cisco Catalyst 6800 Series Switches could allow an unauthenticated, local attacker to bypass Cisco Secure Boot validation checks and load a compromised software image on an affected device.

Out-of-bounds

In DisplayFtmItem in the bootloader, there is an out-of-bounds write due to reading a string without verifying that it's null-terminated. This could lead to a secure boot bypass and a local elevation of privilege enabling code execution as a privileged process with no additional execution...

CVE-2017-13217

CVE-2017-13217 affects the LG Bootloader’s DisplayFtmItem in Android. It is an out-of-bounds write caused by reading a string without verifying it is null-terminated, enabling a local elevation of privilege and a secure-boot bypass that could let code execute with high privileges. Exploitation is...
