CVE-2023-28869Public exploit

Arbitrary file disclosure via symlink-following service

Published Dec 9, 2023 · Updated Nov 26, 2024

Information disclosure in Support Assistant in NCP Secure Enterprise Client before 12.22 allows local users to read arbitrary files. The feature stores diagnostics in a user-controlled NcpSupport temporary directory, then a privileged service follows an attacker-created symbolic link while opening a selected file. The attacker must have a low-privileged account and use the client interface; exploitation exposes only contents the privileged service can read.
