Description

The WBM web application on firmwares prior to 03.02.02 and 03.01.07 on the WAGO PFC100 and PFC2000, respectively, runs on a lighttpd web server and makes use of the FastCGI module, which is intended to provide high performance for all Internet applications without the penalties of Web server APIs. However, the default configuration of this module appears to limit the number of concurrent php-cgi processes to two, which can be abused to cause a denial of service of the entire web server. This affects WAGO PFC200 Firmware version 03.00.39(12) and version 03.01.07(13), and WAGO PFC100 Firmware version 03.00.39(12) and version 03.02.02(14).
