Description

1) Argument injection attack (CVE-ID: CVE-2017-18266)

The vulnerability allows a remote unauthenticated attacker to conduct argument injection attack on the target system.

The weakness exists in the open_envvar function in the xdg-open component due to improper validation of user-supplied input. A remote attacker can trick the victim into following a specially crafted link that is designed to modify the BROWSER environment variable, conduct argument-injection attack, redirect the user's browser traffic to an attacker-controlled site and execute arbitrary commands.
