The vulnerability of the framework for developing network applications, servers, and client protocols using Netty arises from deficiencies in HTTP request processing. This allows attackers to send hidden HTTP requests (HTTP Request Smuggling attack).

The vulnerability of the framework for developing network applications, servers, and client protocols using Netty is related to deficiencies in HTTP request processing. Exploiting this vulnerability allows a malicious actor to send hidden HTTP requests remotely HTTP Request Smuggling attack...

The vulnerability of the DefaultHttp2FrameReader class in the framework for developing network applications, servers, and clients using the Netty protocol allows a attacker to cause a service failure.

The vulnerability of the DefaultHttp2FrameReader class in the network application development framework for protocols like Netty relates to the distribution of resources without any restrictions or regulation. Exploiting this vulnerability can allow a malicious actor to cause service failures...

netty: io.netty/netty-codec-http: Netty: Incorrect HTTP response parsing leads to data confusion

A flaw was found in Netty, an asynchronous, event-driven network application framework. A remote attacker could exploit this vulnerability by sending a specific sequence of HTTP responses 103, followed by a 200 with a GET body, then another 200 for a HEAD request when the client pipelines GET the...

netty-codec-http2: netty-codec-http2: Denial of Service due to resource leak

A flaw was found in netty-codec-http2. A remote attacker could send specially crafted frames that cause a resource leak within the DelegatingDecompressorFrameListener class. This resource leak could lead to an Out Of Memory Error OOME, potentially causing a Denial of Service DoS by taking down th...

netty-codec-redis: Netty's Lack of Lifecycle Cleanup Leads to Pooled ByteBuf Leak in RedisArrayAggregator

A flaw was found in netty-codec-redis. A remote attacker can exploit this vulnerability by repeatedly closing Redis pipeline connections before a Redis array aggregate completes. This leads to a permanent leak of direct-memory buffers, which prevents memory chunks from being returned to the share...

netty-handler: netty-handler: IPv6 subnet rule bypass due to incorrect masking operation

A flaw was found in netty-handler, a component of the Netty network application framework. A remote attacker can exploit an incorrect masking operation in the IpSubnetFilterRule.compareTo function to bypass configured IPv6 subnet rules. This allows valid public IP addresses to circumvent intended...

netty-transport-sctp: Netty-transport-sctp: Denial of Service due to unbounded memory growth from SctpMessage fragments

A flaw was found in netty-transport-sctp. A remote attacker can exploit this vulnerability by sending specially crafted, non-complete Stream Control Transmission Protocol SCTP message fragments. This can lead to unbounded memory growth within the application, causing a Denial of Service DoS...

netty-handler: Netty: Improper trust manager handling leads to hostname verification bypass

A flaw was found in Netty, a network application framework. This vulnerability allows a remote attacker to bypass hostname verification due to improper handling of user-supplied trust managers. When a client is configured with a plain X.509 Trust Manager X509TrustManager, it fails to perform...

netty: io.netty/netty-handler-proxy: Netty: HTTP Header Injection via HttpProxyHandler Disabled Validation

A flaw was found in Netty. The HttpProxyHandler component, which handles HTTP CONNECT requests, does not properly validate user-provided outbound headers. This allows an attacker to inject arbitrary HTTP headers into the CONNECT request sent to the proxy server. This could lead to unexpected...

io.netty/netty-resolver-dns: Netty has Insufficient Bailiwick Validation for NS Records

A flaw was found in Netty's DnsResolveContext. An attacker controlling an authoritative name server for a subdomain can exploit this vulnerability by providing crafted NS records that are insufficiently validated. This allows the attacker to poison the DNS cache for parent domains, bypassing...

netty-codec-haproxy: Netty-codec-haproxy: Denial of Service via malformed HAProxy message

A flaw was found in netty-codec-haproxy, a component of the Netty network application framework. A remote attacker can exploit this vulnerability by sending a specially crafted HAProxy message with a malformed PP2TYPESSL TLV Type-Length-Value header. This can lead to an IndexOutOfBoundsException...

netty-codec-redis: netty-codec-redis: Denial of Service via crafted Redis payloads

A flaw was found in netty-codec-redis. A remote attacker can exploit this vulnerability by sending specially crafted Redis payloads across multiple connections without proper termination. This can exhaust the server's direct memory pool, leading to a Denial of Service DoS condition where legitima...

netty: Netty: High integrity impact due to improper DNS domain name constraint enforcement

A flaw was found in Netty. Netty's DNS Domain Name System codec does not properly enforce domain name constraints as defined in RFC 1035 during both encoding and decoding processes. This vulnerability allows a remote attacker to exploit the decoder using malicious DNS responses or exploit the...

netty: io.netty/netty-codec-mqtt: Netty: Denial of Service due to excessive resource consumption from crafted MQTT 5 header

A flaw was found in Netty, an asynchronous event-driven network application framework.
