Descriptions
Improper Input Validation vulnerability in Apache Tomcat.Tomcat from 11.0.0-M1 through 11.0.0-M11, from 10.1.0-M1 through 10.1.13, from 9.0.0-M1 through 9.0.81 and from 8.5.0 through 8.5.93 did not correctly parse HTTP trailer headers. A specially
crafted, invalid trailer header could cause Tomcat to treat a single
request as multiple requests leading to the possibility of request
smuggling when behind a reverse proxy.
Users are recommended to upgrade to version 11.0.0-M12 onwards, 10.1.14 onwards, 9.0.81 onwards or 8.5.94 onwards, which fix the issue.
Vulnerabilidad de validación de entrada incorrecta en Apache Tomcat.Tomcat desde 11.0.0-M1 hasta 11.0.0-M11, desde 10.1.0-M1 hasta 10.1.13, desde 9.0.0-M1 hasta 9.0.81 y desde 8.5.0 hasta 8.5 .93 no analizaron correctamente los encabezados de las colas HTTP. Un encabezado de avance no válido y especialmente manipulado podría hacer que Tomcat trate una sola solicitud como solicitudes múltiples, lo que genera la posibilidad de contrabando de solicitudes cuando está detrás de un proxy inverso. Se recomienda a los usuarios actualizar a la versión 11.0.0-M12 en adelante, 10.1.14 en adelante, 9.0.81 en adelante o 8.5.94 en adelante, que solucionan el problema.
A flaw was found in Apache Tomcat, where an improper input validation can occur. This flaw allows a malicious user to send a crafted request containing an invalid trailer header, which could be treated as multiple requests, potentially leading to request smuggling when behind a reverse proxy.
