                                      Description
                                      Netskope client prior to 89.x on macOS is impacted by a local privilege escalation vulnerability. The XPC implementation of nsAuxiliarySvc process does not perform validation on new connections before accepting the connection. Thus any low privileged user can connect and call external methods defined in XPC service as root, elevating their privilege to the highest level.

                                      Affected Components: Netskope Client v88.x and earlier on macOS.

                                       

                                      Remediation
                                      Netskope has patched the issue and released a new version of Netskope client.
                                      Customers are advised to upgrade the software to the latest version (89 or above).
