CVE-2024-58315

Tosibox Key Service 3.3.0 contains an unquoted service path vulnerability that allows local non-privileged users to potentially execute code with elevated system privileges. Attackers can exploit the service startup process by inserting malicious code in the system root path, enabling unauthorized code execution during application startup or system reboot.

What this means for your business

It affects Tosibox Key. It matters if your company, or a supplier that handles your data, runs it.
Code showing how to exploit it has been published, but real attacks have not been confirmed.
An attacker can use it only with access to the machine itself, with an ordinary user login, and without anyone at your company clicking anything.
FIRST's prediction model gives it a 0.2% chance of attack attempts being seen in the next 30 days, ranking above 13% of all known flaws.

What to do

1Check whether your company or your suppliers run Tosibox Key, and which version. The affected versions are listed further down this page.
