GeneralSandman TinyWeb
Exploitation
Public or AI PoC available; prioritize validation
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

GeneralSandman TinyWeb是GeneralSandman个人开发者开源的一款嵌入式Web服务器软件。 GeneralSandman TinyWeb 0.0.8及之前版本存在异常处理不当漏洞，该漏洞源于HttpParser::execute()函数在版本解析失败时未能分配Url对象，导致后续buildResponse()函数解引用空指针，使得未认证远程攻击者通过发送畸形HTTP请求行可导致工作进程崩溃，多次重复可导致服务器永久离线。

Vulnerability Title
TinyWeb 0.0.8 Null Pointer Dereference DoS via Malformed HTTP Request
Source: CVE Program / CVE List V5
Vulnerability 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.
