CVE-2022-41915 2 Debian, Netty 2 Debian Linux, Netty 2023-03-01 N/A 6.5 MEDIUM
Netty project is an event-driven asynchronous network application framework. Starting in version 4.1.83.Final and prior to 4.1.86.Final, when calling `DefaultHttpHeadesr.set` with an _iterator_ of values, header value validation was not performed, allowing malicious header values in the iterator to perform HTTP Response Splitting. This issue has been patched in version 4.1.86.Final. Integrators can work around the issue by changing the `DefaultHttpHeaders.set(CharSequence, Iterator<?>)` call, into a `remove()` call, and call `add()` in a loop over the iterator of values.
CVE-2022-41881 2 Debian, Netty 2 Debian Linux, Netty 2023-03-01 N/A 7.5 HIGH
Netty project is an event-driven asynchronous network application framework. In versions prior to 4.1.86.Final, a StackOverflowError can be raised when parsing a malformed crafted message due to an infinite recursion. This issue is patched in version 4.1.86.Final. There is no workaround, except using a custom HaProxyMessageDecoder.
CVE-2021-37136 5 Debian, Netapp, Netty and 2 more 19 Debian Linux, Oncommand Insight, Netty and 16 more 2023-02-24 5.0 MEDIUM 7.5 HIGH
The Bzip2 decompression decoder function doesn't allow setting size restrictions on the decompressed output data (which affects the allocation size used during decompression). All users of Bzip2Decoder are affected. The malicious input can trigger an OOME and so a DoS attack
CVE-2021-37137 5 Debian, Netapp, Netty and 2 more 12 Debian Linux, Oncommand Insight, Netty and 9 more 2023-02-24 5.0 MEDIUM 7.5 HIGH
The Snappy frame decoder function doesn't restrict the chunk length which may lead to excessive memory usage. Beside this it also may buffer reserved skippable chunks until the whole chunk was received which may lead to excessive memory usage as well. This vulnerability can be triggered by supplying malicious input that decompresses to a very big size (via a network stream or a file) or by sending a huge skippable chunk.
CVE-2021-43797 5 Debian, Netapp, Netty and 2 more 18 Debian Linux, Oncommand Workflow Automation, Snapcenter and 15 more 2023-02-24 4.3 MEDIUM 6.5 MEDIUM
Netty is an asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients. Netty prior to version 4.1.71.Final skips control chars when they are present at the beginning / end of the header name. It should instead fail fast as these are not allowed by the spec and could lead to HTTP request smuggling. Failing to do the validation might cause netty to "sanitize" header names before it forward these to another remote system when used as proxy. This remote system can't see the invalid usage anymore, and therefore does not do the validation itself. Users should upgrade to version 4.1.71.Final.
CVE-2014-0193 1 Netty 1 Netty 2023-02-12 5.0 MEDIUM N/A
WebSocket08FrameDecoder in Netty 3.6.x before 3.6.9, 3.7.x before 3.7.1, 3.8.x before 3.8.2, 3.9.x before 3.9.1, and 4.0.x before 4.0.19 allows remote attackers to cause a denial of service (memory consumption) via a TextWebSocketFrame followed by a long stream of ContinuationWebSocketFrames.
CVE-2022-24823 3 Netapp, Netty, Oracle 5 Active Iq Unified Manager, Oncommand Workflow Automation, Snapcenter and 2 more 2022-12-03 1.9 LOW 5.5 MEDIUM
Netty is an open-source, asynchronous event-driven network application framework. The package `io.netty:netty-codec-http` prior to version 4.1.77.Final contains an insufficient fix for CVE-2021-21290. When Netty's multipart decoders are used local information disclosure can occur via the local system temporary directory if temporary storing uploads on the disk is enabled. This only impacts applications running on Java version 6 and lower. Additionally, this vulnerability impacts code running on Unix-like systems, and very old versions of Mac OSX and Windows as they all share the system temporary directory between all users. Version 4.1.77.Final contains a patch for this vulnerability. As a workaround, specify one's own `java.io.tmpdir` when starting the JVM or use DefaultHttpDataFactory.setBaseDir(...) to set the directory to something that is only readable by the current user.
CVE-2021-21409 5 Debian, Netapp, Netty and 2 more 18 Debian Linux, Oncommand Api Services, Oncommand Workflow Automation and 15 more 2022-05-12 4.3 MEDIUM 5.9 MEDIUM
Netty is an open-source, asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients. In Netty (io.netty:netty-codec-http2) before version 4.1.61.Final there is a vulnerability that enables request smuggling. The content-length header is not correctly validated if the request only uses a single Http2HeaderFrame with the endStream set to to true. This could lead to request smuggling if the request is proxied to a remote peer and translated to HTTP/1.1. This is a followup of GHSA-wm47-8v5p-wjpj/CVE-2021-21295 which did miss to fix this one case. This was fixed as part of 4.1.61.Final.
CVE-2021-21295 6 Apache, Debian, Netapp and 3 more 8 Kudu, Zookeeper, Debian Linux and 5 more 2022-05-12 2.6 LOW 5.9 MEDIUM
Netty is an open-source, asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients. In Netty (io.netty:netty-codec-http2) before version 4.1.60.Final there is a vulnerability that enables request smuggling. If a Content-Length header is present in the original HTTP/2 request, the field is not validated by `Http2MultiplexHandler` as it is propagated up. This is fine as long as the request is not proxied through as HTTP/1.1. If the request comes in as an HTTP/2 stream, gets converted into the HTTP/1.1 domain objects (`HttpRequest`, `HttpContent`, etc.) via `Http2StreamFrameToHttpObjectCodec `and then sent up to the child channel's pipeline and proxied through a remote peer as HTTP/1.1 this may result in request smuggling. In a proxy case, users may assume the content-length is validated somehow, which is not the case. If the request is forwarded to a backend channel that is a HTTP/1.1 connection, the Content-Length now has meaning and needs to be checked. An attacker can smuggle requests inside the body as it gets downgraded from HTTP/2 to HTTP/1.1. For an example attack refer to the linked GitHub Advisory. Users are only affected if all of this is true: `HTTP2MultiplexCodec` or `Http2FrameCodec` is used, `Http2StreamFrameToHttpObjectCodec` is used to convert to HTTP/1.1 objects, and these HTTP/1.1 objects are forwarded to another remote peer. This has been patched in 4.1.60.Final As a workaround, the user can do the validation by themselves by implementing a custom `ChannelInboundHandler` that is put in the `ChannelPipeline` behind `Http2StreamFrameToHttpObjectCodec`.
CVE-2021-21290 5 Debian, Netapp, Netty and 2 more 13 Debian Linux, Active Iq Unified Manager, Cloud Secure Agent and 10 more 2022-05-12 1.9 LOW 5.5 MEDIUM
Netty is an open-source, asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients. In Netty before version 4.1.59.Final there is a vulnerability on Unix-like systems involving an insecure temp file. When netty's multipart decoders are used local information disclosure can occur via the local system temporary directory if temporary storing uploads on the disk is enabled. On unix-like systems, the temporary directory is shared between all user. As such, writing to this directory using APIs that do not explicitly set the file/directory permissions can lead to information disclosure. Of note, this does not impact modern MacOS Operating Systems. The method "File.createTempFile" on unix-like systems creates a random file, but, by default will create this file with the permissions "-rw-r--r--". Thus, if sensitive information is written to this file, other local users can read this information. This is the case in netty's "AbstractDiskHttpData" is vulnerable. This has been fixed in version 4.1.59.Final. As a workaround, one may specify your own "java.io.tmpdir" when you start the JVM or use "DefaultHttpDataFactory.setBaseDir(...)" to set the directory to something that is only readable by the current user.
CVE-2020-11612 5 Debian, Fedoraproject, Netapp and 2 more 13 Debian Linux, Fedora, Oncommand Api Services and 10 more 2022-04-26 5.0 MEDIUM 7.5 HIGH
The ZlibDecoders in Netty 4.1.x before 4.1.46 allow for unbounded memory allocation while decoding a ZlibEncoded byte stream. An attacker could send a large ZlibEncoded byte stream to the Netty server, forcing the server to allocate all of its free memory to a single decoder.
CVE-2019-16869 4 Canonical, Debian, Netty and 1 more 5 Ubuntu Linux, Debian Linux, Netty and 2 more 2022-03-30 5.0 MEDIUM 7.5 HIGH
Netty before 4.1.42.Final mishandles whitespace before the colon in HTTP headers (such as a "Transfer-Encoding : chunked" line), which leads to HTTP request smuggling.
CVE-2019-20444 5 Canonical, Debian, Fedoraproject and 2 more 7 Ubuntu Linux, Debian Linux, Fedora and 4 more 2021-09-14 6.4 MEDIUM 9.1 CRITICAL
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."
CVE-2019-20445 6 Apache, Canonical, Debian and 3 more 8 Spark, Ubuntu Linux, Debian Linux and 5 more 2021-09-14 6.4 MEDIUM 9.1 CRITICAL
HttpObjectDecoder.java in Netty before 4.1.44 allows a Content-Length header to be accompanied by a second Content-Length header, or by a Transfer-Encoding header.
CVE-2020-7238 4 Debian, Fedoraproject, Netty and 1 more 6 Debian Linux, Fedora, Netty and 3 more 2021-05-27 5.0 MEDIUM 7.5 HIGH
Netty 4.1.43.Final allows HTTP Request Smuggling because it mishandles Transfer-Encoding whitespace (such as a [space]Transfer-Encoding:chunked line) and a later Content-Length header. This issue exists because of an incomplete fix for CVE-2019-16869.
CVE-2016-4970 3 Apache, Netty, Redhat 4 Cassandra, Netty, Jboss Data Grid and 1 more 2021-02-13 7.8 HIGH 7.5 HIGH
handler/ssl/OpenSslEngine.java in Netty 4.0.x before 4.0.37.Final and 4.1.x before 4.1.1.Final allows remote attackers to cause a denial of service (infinite loop).
CVE-2014-3488 1 Netty 1 Netty 2020-02-19 5.0 MEDIUM N/A
The SslHandler in Netty before 3.9.2 allows remote attackers to cause a denial of service (infinite loop and CPU consumption) via a crafted SSLv2Hello message.
CVE-2015-2156 3 Lightbend, Netty, Playframework 3 Play Framework, Netty, Play Framework 2019-11-25 4.3 MEDIUM 7.5 HIGH
Netty before 3.9.8.Final, 3.10.x before 3.10.3.Final, 4.0.x before 4.0.28.Final, and 4.1.x before 4.1.0.Beta5 and Play Framework 2.x before 2.3.9 might allow remote attackers to bypass the httpOnly flag on cookies and obtain sensitive information by leveraging improper validation of cookie name and value characters.
