Netskope Client Configuration Tampering with Local MITM
Netskope has identified a potential gap in its agent (Netskope Client) in which a malicious insider can potentially tamper the Netskope Client configuration by performing MITM (Man-in-the-Middle) activity on the Netskope Client communication channel. A successful exploitation would require administrative privileges on the machine, and could result in temporarily altering the configuration of Netskope Client or permanently disabling or removing the agent from the machine.

Customers can apply the fix by enabling the “Secure Configuration” option from the tenant under Settings -> Security Cloud Platform -> Netskope Client -> MDM Distribution -> Secure Enrollment page. Customers are recommended to upgrade the Netskope Client to the latest versions of R123, R126, R129 or higher and adopt “Netskope Client Secure Configuration Service” for APIs.
