What is CVE-2019-5149?

The WBM web application deployed on WAGO PFC100 and PFC2000 devices running on outdated firmware versions is susceptible to a denial of service scenario. Owing to the default configuration of the FastCGI module, the application limits the number of concurrent php-cgi processes to only two. This limitation can be exploited, leading to a potential overload and, consequently, a denial of service for the entire web server. Users of these devices should ensure they are running the latest firmware versions to mitigate any associated risks.
