aiohttp is an asynchronous HTTP client/server framework for asyncio and Python. Improper validation makes it possible for an attacker to modify the HTTP request (e.g. insert a new header) or even create a new HTTP request if the attacker controls the HTTP method. The vulnerability occurs only if the attacker can control the HTTP method (GET, POST etc.) of the request. If the attacker can control the HTTP version of the request it will be able to modify the request (request smuggling). This issue has been patched in version 3.9.0.
aiohttp es un framework cliente/servidor HTTP asíncrono para asyncio y Python. Una validación inadecuada hace posible que un atacante modifique la solicitud HTTP (por ejemplo, inserte un nuevo encabezado) o incluso cree una nueva solicitud HTTP si el atacante controla el método HTTP. La vulnerabilidad ocurre sólo si el atacante puede controlar el método HTTP (GET, POST, etc.) de la solicitud. Si el atacante puede controlar la versión HTTP de la solicitud, podrá modificar la solicitud (contrabando de solicitudes). Este problema se solucionó en la versión 3.9.0.
A flaw was found in Aiohttp. This issue may allow an attacker to send a crafted HTTP request to the server and smuggle arbitrary HTTP headers due to improper validation of HTTP requests during the processing of the HTTP request method. By exploiting this flaw, an attacker can manipulate HTTP requests and potentially poison the HTTP cache for phishing attacks.
