"The version of IBM HTTP Server running on the remote host is affected by an HTTP request smuggling vulnerability
related to Apache HTTP Server. The chunked transfer coding implementation in the Apache HTTP Server before 2.4.14 does
not properly parse chunk headers, which allows remote attackers to conduct HTTP request smuggling attacks via a crafted
request, related to mishandling of large chunk-size values and invalid chunk-extension characters in
modules/http/http_filters.c.
