Motorola netOctopus nantsys.sys privilege escalation
| netoctopus-nantsys-privilege-escalation (39503) |  High Risk |
Description:
Motorola's netOctopus could allow a local attacker to gain elevated privileges on the system, caused by the exposure of the world-writable \\.\NantSys device interface when the nantsys.sys device driver is installed. By modifying SYSENTER_EIP_MSR, a local attacker could exploit this vulnerability to execute arbitrary code on the system with kernel privileges.
