TinyWeb versions up to 0.0.8 are vulnerable to a null pointer dereference that can be exploited by unauthenticated remote attackers through malformed HTTP requests, leading to the crashing of worker processes. This vulnerability can cause a denial of service, rendering the server inoperable until it is manually restarted. Organizations using TinyWeb should prioritize patching this vulnerability to prevent potential service disruptions.

Original NVD Description

TinyWeb through 0.0.8 contains a null pointer dereference vulnerability that allows unauthenticated remote attackers to crash worker processes by sending a malformed HTTP request line with an invalid version string. The HttpParser::execute() function fails to allocate the Url object when version parsing fails, leaving the url pointer NULL, and buildResponse() subsequently dereferences this NULL pointer without checking the valid_requ flag, producing a SIGSEGV that terminates the worker process and, when repeated across all workers, takes the server permanently offline until manually restarted.
