Netskope Client for Windows contains an exposed IOCTL interface with insufficient access control (CWE-782). A malicious insider possessing administrative privileges can exploit this by sending specially crafted IOCTL requests to the driver, potentially bypassing the client's anti-tampering protections. This vulnerability affects all versions of the Netskope Client prior to R138. No official patch or remediation level has been provided in the available data.

Successful exploitation allows a privileged insider to bypass all anti-tampering protections of the Netskope Client, potentially undermining the integrity and security controls enforced by the client software. This could facilitate unauthorized modifications or disablement of security features.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict administrative access to trusted personnel only to reduce the risk of exploitation. Monitor for updates from Netskope regarding patches or mitigations.
