CyberRota Analysis
AI-GeneratedThe vulnerability affects tiny-http versions up to 0.12.0, allowing remote attackers to exploit improper parsing of the Transfer-Encoding header, leading to HTTP request smuggling. This can result in desynchronized request handling between the library and front-end proxies, potentially allowing attackers to manipulate requests and exhaust server resources without triggering errors. Organizations using tiny-http should prioritize patching this vulnerability to mitigate risks associated with request smuggling and resource exhaustion.

Original NVD Description
tiny-http through 0.12.0 contains an HTTP request smuggling vulnerability that allows remote attackers to desynchronize request framing by sending a Transfer-Encoding header with any value, including non-chunked codings, which causes the library to unconditionally apply chunk-decoding and discard Content-Length. Attackers can exploit the discrepancy between tiny_http's improper Transfer-Encoding parsing and a correctly-implemented front-end proxy to produce two distinct interpretations of a single byte stream, enabling request smuggling, and can additionally send non-chunked bodies with non-chunked Transfer-Encoding values to cause failed body reads that tie up connections and consume worker threads without signaling errors to clients.
