Descriptions
HttpObjectDecoder.java in Netty before 4.1.44 allows an HTTP header that lacks a colon, which might be interpreted as a separate header with an incorrect syntax, or might be interpreted as an "invalid fold."
El archivo HttpObjectDecoder.java en Netty versiones anteriores a 4.1.44, permite un encabezado HTTP que carece de ":" dos puntos, que podría ser interpretado como un encabezado separado con una sintaxis incorrecta, o podría ser interpretado como un "invalid fold."
A HTTP smuggling flaw was found in HttpObjectDecoder.java in Netty in versions prior to version 4.1.44. HTTP headers with an invalid fold, in this case CRLF (carriage return, line feed) without being followed by SP (space) or HTAB (horizontal tab), result in situations where headers can be misread. Data integrity is the highest threat with this vulnerability.
