io.netty/netty-codec-http: Netty: Incomplete validation of malformed Transfer-Encoding allows HTTP request smuggling

A flaw was found in Netty's HTTP/1 decoder. Incomplete validation of malformed Transfer-Encoding headers allows a remote attacker to perform HTTP request smuggling. By sending specially crafted HTTP requests, an attacker can inject arbitrary HTTP requests, potentially bypassing security controls ...

io.netty/netty-codec-http: Netty: HTTP Request Smuggling due to control characters in the chunk-size line

A flaw was found in Netty. A remote attacker could exploit this by sending a specially crafted HTTP request that includes control characters within the chunk-size line. This bypasses the intended strict validation, allowing the attacker to inject arbitrary HTTP requests. This vulnerability can le...

io.netty/netty-codec-http: Netty RtspDecoder Method-Token Smuggling via Trailing Control Byte

A flaw was found in Netty RtspDecoder. The RtspMethods.valueOf function incorrectly strips trailing control bytes from method tokens in Real-Time Streaming Protocol RTSP requests. A remote attacker can exploit this by sending a specially crafted RTSP request, leading to method-token smuggling. Th...

io.netty/netty-codec-http: Netty split Transfer-Encoding fields bypass final-chunked validation and enable request smuggling

A flaw was found in Netty's HTTP/1.1 decoder. This vulnerability allows a remote attacker to bypass Transfer-Encoding header validation by splitting the Transfer-Encoding field across multiple headers, with the last field containing a non-final transfer coding like gzip or deflate. This bypass ca...

io.netty/netty-codec-http: Netty: HTTP request smuggling via post-digit whitespace in chunk-size parsing

A flaw was found in Netty's netty-codec-http component. A remote attacker could exploit this vulnerability by sending a specially crafted HTTP/1.1 chunk-size token that includes post-digit whitespace. This incorrect parsing of the chunk size can lead to HTTP request smuggling. This allows an...

io.netty/netty-codec-http2: Netty: HTTP/2 header field values are not validated by default (CR/LF/NUL passthrough)

A flaw was found in Netty's HTTP/2 stack. This vulnerability allows a remote attacker to inject prohibited characters, such as NUL, Line Feed, and Carriage Return, into HTTP/2 header field values due to insufficient validation. When these values cross an HTTP/2 to HTTP/1.1 translation boundary,...
