CyberRota Analysis

AI-Generated

TinyWeb versions up to 0.0.8 are vulnerable to a memory leak that allows unauthenticated attackers to exhaust system memory by sending well-formed HTTP requests. This vulnerability can lead to service disruption as the memory consumption grows significantly with each request, ultimately causing the worker process to crash. Organizations using TinyWeb should prioritize patching this issue to prevent potential denial-of-service attacks.

Original NVD Description

TinyWeb through 0.0.8 contains a memory leak vulnerability that allows unauthenticated attackers to exhaust available memory by sending ordinary well-formed HTTP requests. Each request causes HttpParser::execute() to allocate Url objects, HttpHeaders objects, and HttpHeader instances via raw new expressions that are never freed due to missing destructors and unreachable delete calls, causing worker resident memory to grow monotonically by approximately 20 to 28 kB per request until the worker process is killed.
