CVE-2024-7240

SYSTEM code execution via symbolic-link file creation

Published Nov 22, 2024 · Updated Dec 5, 2024

Link following in F-Secure Total 19.2 allows local users to execute arbitrary code as SYSTEM through the WithSecure plugin hosting service. The service follows an attacker-created symbolic link when creating a file, redirecting the privileged write to an attacker-chosen location. Exploitation requires an administrator to interact with the application, after which attacker-controlled code runs with SYSTEM privileges.
