Vulnerability from fkie_nvd - Published: 2024-07-08 21:15 - Updated: 2024-11-21 09:48
Severity ?
Summary
A vulnerability was found in Undertow, where the chunked response hangs after the body was flushed. The response headers and body were sent but the client would continue waiting as Undertow does not send the expected 0\r\n termination of the chunked response. This results in uncontrolled resource consumption, leaving the server side to a denial of service attack. This happens only with Java 17 TLSv1.3 scenarios.

"value": "Se encontr\u00f3 una vulnerabilidad en Undertow, donde la respuesta fragmentada se suspende despu\u00e9s de que se lav\u00f3 el cuerpo. Los encabezados y el cuerpo de la respuesta se enviaron, pero el cliente continuar\u00eda esperando ya que Undertow no env\u00eda la terminaci\u00f3n 0\\r\\n esperada de la respuesta fragmentada. Esto da como resultado un consumo descontrolado de recursos, dejando al lado del servidor expuesto a un ataque de denegaci\u00f3n de servicio. Esto sucede solo con escenarios Java 17 TLSv1.3."
