CVE Published:
11 March 2020

Summary

The WBM web application deployed on WAGO PFC100 and PFC2000 devices running on outdated firmware versions is susceptible to a denial of service scenario.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.

Affected Version(s)

WAGO PFC100 Firmware version 03.00.39(12)

WAGO PFC100 Firmware version 03.02.02(14)

WAGO PFC200 Firmware version 03.00.39(12)
