A flaw was found in Eclipse Vert.x. The `DefaultRedirectHandler` in `vertx-core` improperly handles HTTP 30x redirects by propagating all request headers, including sensitive authentication and session credentials, to cross-origin redirect destinations. An attacker can exploit this by redirecting a Vert.x HttpClient request to a malicious host. This allows the attacker to capture sensitive information such as bearer tokens, basic authentication credentials, session cookies, and API keys, leading to unauthorized access or further attacks.

A flaw was found in Eclipse Vert.x Web Client. The WebClientSession component does not properly validate the Domain attribute of a Set-Cookie response header against the originating server's domain. This vulnerability allows a remote attacker to inject a cookie scoped to an arbitrary third-party domain. When the victim application subsequently sends a request to the targeted domain, the injected cookie is presented, potentially leading to information disclosure and unauthorized access to sensitive data through the attacker's account on that service.

A flaw was found in Quarkus REST. An unauthenticated remote attacker can exploit this vulnerability by sending a crafted multipart/form-data request with an excessively large header section. This unbounded accumulation of MIME part-header bytes can exhaust the Java Virtual Machine (JVM) heap memory, leading to an OutOfMemoryError. The primary consequence is a denial of service, causing the application to crash.

A flaw was found in Apache HttpComponents Core. This vulnerability, located in the HTTP/2 HPACK decoder, allows a remote attacker to cause a denial of service. By sending oversized compressed header blocks, an attacker can exhaust memory resources before the system's configured header list size limit is applied. This can lead to the affected system becoming unresponsive.

A flaw was found in Netty, a network application framework. A remote attacker, by sending a specially crafted SPDY/3.1 SETTINGS frame, could cause the SPDY SETTINGS decoder to create a large number of map entries. This excessive processing and memory allocation can lead to a denial of service (DoS) due to heap growth and increased CPU usage.

A flaw was found in Netty, a network application framework. A remote attacker could exploit a vulnerability in the SPDY header decoding process. By sending a specially crafted, small compressed header block, the attacker can cause it to expand significantly during decompression, leading to excessive CPU usage and memory allocation. This can result in a denial of service (DoS) due to resource exhaustion.

Important
A flaw was found in Netty. A remote attacker can exploit a vulnerability in the `SpdyHttpDecoder` handler of Netty's SPDY-to-HTTP codec. When processing a client-initiated `SYN_STREAM` frame, the decoder fails to release allocated memory if the stream is reset or content limits are exceeded. This oversight leads to native memory exhaustion, which can result in a Denial of Service (DoS) for the affected system.

A flaw was found in Netty, a network application framework. A remote attacker can bypass security controls in the `CorsHandler` component by sending a specially crafted request with a null origin header. This bypasses the intended access restrictions, allowing unauthorized requests to reach the backend application. This could lead to a compromise of data integrity by allowing unauthorized actions.

Important
A flaw was found in Netty, a network application framework. A remote, unauthenticated attacker can exploit this vulnerability by sending specially crafted HTTP/2 DATA frames to applications that use Netty and have HTTP/2 content decompression enabled. This can lead to memory exhaustion, causing the application to crash and resulting in a Denial of Service (DoS). The issue occurs because the framework fails to release retained memory buffers when processing DATA frames for a stream whose decompressor has already been closed.

A flaw was found in the Netty netty-codec-http component. A remote attacker can send HTTP requests containing highly compressed data. The HTTP decoder in netty-codec-http fails to properly limit the decompression of this content, causing the system to consume excessive memory. This can lead to memory exhaustion and a denial of service (DoS), making the service unavailable to legitimate users.

A flaw was found in Netty's netty-codec-http2 component. The HTTP/2 encoder does not properly handle special characters in HTTP headers.

Such attacks can enable an attacker to manipulate web content or inject malicious headers.

Impact
Moderate
A flaw was found in Netty's HttpPostRequestEncoder, a widely used Java networking library component responsible for constructing multipart HTTP request bodies. The issue arises because user-supplied filenames and field names are directly embedded into Content-Disposition MIME headers without any validation or sanitization of CRLF (\r\n) characters. Since MIME headers are delimited by CRLF sequences, an attacker who controls the filename in a multipart upload can inject arbitrary MIME headers into the request body. This may lead to limited Content-Type spoofing or header manipulation against middleware or storage layers processing the request, though the practical impact is constrained by the context in which Netty is deployed.

The issue arises because user-supplied filenames and field names are directly embedded into Content-Disposition MIME headers without any validation or sanitization of CRLF (\\r\\n) characters. Since MIME headers are delimited by CRLF sequences, an attacker who controls the filename in a multipart upload can inject arbitrary MIME headers into the request body. This may lead to limited Content-Type spoofing or header manipulation against middleware or storage layers processing the request, though the practical impact is constrained by the context in which Netty is deployed.",
