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-http: Netty: Denial of Service via unbounded HttpServerCodec HTTP/1.1 pipeline queue
A flaw was found in Netty's HttpServerCodec. A remote, unauthenticated attacker can exploit this vulnerability by pipelining HTTP/1.1 requests on a single connection and withholding reads. This action causes the methodOverflowQueue to grow without limit, leading to unbounded heap memory consumpti...
io.netty/netty-codec-http: Netty: Unbounded Per-Connection Queue Growth in WebSocketServerExtensionHandler Leads to Denial of Service
A flaw was found in Netty's WebSocketServerExtensionHandler. A remote, unauthenticated attacker can exploit this vulnerability by using HTTP/1.1 pipelining to send requests faster than the application can respond. This leads to an unbounded growth of a per-connection queue, consuming excessive...
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: Denial of Service via unbounded concurrent SPDY streams
A flaw was found in Netty. SpdySessionHandler accepts an unlimited number of concurrent remote-initiated streams because localConcurrentStreams defaults to Integer.MAXVALUE and the handler provides no API to change it. A remote peer can open a SPDY connection and send a large number of SYNSTREAM...
io.netty/netty-codec-http: Netty: Denial of Service via unbounded SPDY concurrent streams
A flaw was found in Netty. This vulnerability allows a remote attacker to cause a Denial of Service DoS by exhausting server memory. Because the SPDY session handler does not restrict the number of concurrent streams initiated by a remote peer, an attacker can transmit an excessive volume of stre...
io.netty/netty-codec-http: Netty: HTTP response desynchronization via HttpServerCodec
A flaw was found in Netty's HttpServerCodec. A remote attacker can exploit this vulnerability to cause HTTP response desynchronization, leading to response splitting and potential information disclosure. By sending pipelined requests with informational headers followed by another request, the...
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...
Important: Red Hat Security Advisory: Red Hat JBoss Enterprise Application Platform 8.1.9 security update
A security update is now available for Red Hat JBoss Enterprise Application Platform 8.1. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available for each...
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: 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: Unbounded Per-Connection Queue Growth in WebSocketServerExtensionHandler Leads to Denial of Service
A flaw was found in Netty's WebSocketServerExtensionHandler. A remote, unauthenticated attacker can exploit this vulnerability by using HTTP/1.1 pipelining to send requests faster than the application can respond. This leads to an unbounded growth of a per-connection queue, consuming excessive...
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-http2: HTTP/1 authority-form CONNECT is translated to malformed HTTP/2 CONNECT with Host-controlled :authority
A flaw was found in Netty's HTTP/2 codec. When converting HTTP/1 CONNECT requests to HTTP/2, the component incorrectly uses the Host header instead of the CONNECT authority-form request-target for the tunnel authority. A remote attacker can exploit this by supplying a different Host header, leadi...
io.netty/netty-codec-http2: io.netty/netty-codec-http3: Netty: HTTP/2 and HTTP/3 Extended CONNECT requests are downgraded as regular CONNECT requests
A flaw was found in Netty. A remote attacker could exploit this vulnerability by sending specially crafted HTTP/2 or HTTP/3 Extended CONNECT requests. Netty's HTTP-object conversion path incorrectly processes these requests as regular HTTP/1.1 CONNECT requests, leading to a loss of critical...
io.netty/netty-codec-http2: Netty: HTTP/2 HpackEncoder DoS with large table size
A flaw was found in Netty's HTTP/2 HpackEncoder. A remote attacker can exploit this by sending HTTP/2 SETTINGS frames with a very large MAXHEADERTABLESIZE. This causes the HpackEncoder to store an excessive number of unique headers, leading to increased CPU usage and memory consumption, ultimatel...
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,...
io.netty/netty-codec-http2: HTTP/1 absolute-form Host mismatch is translated to HTTP/2 :authority, overriding the request-target authority
A flaw was found in Netty. A remote unauthenticated attacker can exploit a vulnerability in Netty's HTTP/1 to HTTP/2 conversion process. When an HTTP/1 request includes both an absolute-form request-target and a conflicting Host header, Netty incorrectly prioritizes the Host header for the HTTP/2...
io.netty/netty-codec-haproxy: Netty: HAProxy PROXY-v2 nested-TLV grandchild ByteBuf reference-count leak (incomplete fix of PR #16881)
A flaw was found in Netty. A reference-count leak in the HAProxy PROXY-v2 message decoder allows a remote, unauthenticated attacker to send specially crafted PROXY-protocol v2 headers. This can lead to memory exhaustion, resulting in a Denial of Service DoS for the affected system...
