CVE-2019-5135
An exploitable timing discrepancy vulnerability exists in the authentication functionality of the Web-Based Management (WBM) web application on WAGO PFC100/200 controllers.
Does this matter?
Lower severity and a low EPSS score (1.05%). Track it; it rarely justifies an emergency change on its own.
