CVE-2023-4996

Summary

CVE-2023-4996 is a vulnerability affecting Netskope's NSClient product in versions 100 and below. A malicious non-admin user can exploit this issue by creating a specially-crafted package, leading to the Netskope client being disabled. The underlying cause is that the user control code executed by the Windows ServiceController fails to validate the user's permissions before executing the code. This vulnerability allows the user control code, which holds the necessary permissions to terminate the NSClient service, to be manipulated, resulting in the client being disabled.
