Yubico YubiKey Manager < 1.2.6 Privilege Escalation

high Nessus Plugin ID 269981

Language:

Synopsis

A data collection agent on the remote Windows host is affected by a privilege escalation vulnerability.

Description

The version of Yubico YubiKey Manager installed on the remote host is prior to 1.2.6. It is, therefore, affected by a vulnerability. Yubico ykman-gui (aka YubiKey Manager GUI) before 1.2.6 on Windows, when Edge is not used, allows privilege escalation because browser windows can open as Administrator.
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Yubico YubiKey Manager version 1.2.6 or later.
