Synopsis

lighttpd 1.4.31 http_request_split_value Function Header Handling DoS

Description

According to its banner, the version of lighttpd running on the remote host is 1.4.31. It is, therefore, affected by a denial of service vulnerability. An error in the http_request_split_value() function in 'src/request.c' can cause the application to enter an endless loop when handling specially crafted 'Connection' header requests.

Note that the scanner has not tested for this issue but has instead relied only on the version in the server's banner.

Solution

Upgrade to lighttpd version 1.4.32 or later.
