                                        Description
                                        Netskope was notified about a potential gap in its agent (Netskope Client) in which a malicious insider can tamper with the Netskope Client configuration by performing MITM (Man-in-the-Middle) attacks on the Netskope Client communication channel. A successful exploitation would require administrative privileges on the machine. A successful exploit can result in temporarily altering the configuration of Netskope Client or permanently disabling or removing the agent from the machine.

                                        Remediation
                                        Netskope has added the fix “Secure Configuration Service” as an option in the Tenant UI. Upgrading Netskope Clients to R123(123.0.16), 126(126.0.9), R129 or higher is a prerequisite for the Secure Configuration Service.

                                        Workaround
                                        There are no workarounds to protect against the security issue apart from preventing users from installing MITM tools such as Burp and ZAP, or preventing users from installing any 3rd party certificates in Operating Systems trust stores.
