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 arbitary code on the system with kernel privileges.
Platforms Affected:
- Motorola, nantsys.sys driver 5.0.0.115
- Motorola, netOctupus 5.1.2 build 1011
Remedy:
Refer to the Motorola Web site for patch, upgrade, or suggested workaround information. See References.
Consequences:
Gain Privileges
