Name of the Vulnerable Software and Affected Versions Netskope Client versions prior to R138
Description A gap exists in the Netskope Client for Windows systems. A malicious insider with administrative privileges can tamper with the customer IOCTL (Input/Output Control, a mechanism used by applications to communicate with device drivers) by sending crafted IOCTL requests to the driver. This can lead to the bypassing of all anti-tampering protections for the NSClient.
Recommendations Update to version R138 or later.
