SYSTEM code execution via relative extraction path
Published Jun 15, 2023 · Updated Aug 28, 2024
Path traversal in Netskope Client for Windows 99 and earlier allows local users to execute code with NT\SYSTEM privileges. The localhost service's connection handler uses a relative path while downloading and extracting configuration files, allowing attacker-controlled paths to write arbitrary files into privileged locations. Any local low-privileged user able to connect to the service can turn that privileged file write into SYSTEM-level code execution.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
