CVE-2020-26281 1 Rust-lang 1 Async-h1 2024-02-04 5.8 MEDIUM 7.5 HIGH
async-h1 is an asynchronous HTTP/1.1 parser for Rust (crates.io). There is a request smuggling vulnerability in async-h1 before version 2.3.0. This vulnerability affects any webserver that uses async-h1 behind a reverse proxy, including all such Tide applications. If the server does not read the body of a request which is longer than some buffer length, async-h1 will attempt to read a subsequent request from the body content starting at that offset into the body. One way to exploit this vulnerability would be for an adversary to craft a request such that the body contains a request that would not be noticed by a reverse proxy, allowing it to forge forwarded/x-forwarded headers. If an application trusted the authenticity of these headers, it could be misled by the smuggled request. Another potential concern with this vulnerability is that if a reverse proxy is sending multiple http clients' requests along the same keep-alive connection, it would be possible for the smuggled request to specify a long content and capture another user's request in its body. This content could be captured in a post request to an endpoint that allows the content to be subsequently retrieved by the adversary. This has been addressed in async-h1 2.3.0 and previous versions have been yanked.
CVE-2021-25762 1 Jetbrains 1 Ktor 2024-02-04 5.0 MEDIUM 5.3 MEDIUM
In JetBrains Ktor before 1.4.3, HTTP Request Smuggling was possible.
CVE-2021-21299 1 Hyper 1 Hyper 2024-02-04 6.8 MEDIUM 8.1 HIGH
hyper is an open-source HTTP library for Rust (crates.io). In hyper from version 0.12.0 and before versions 0.13.10 and 0.14.3 there is a vulnerability that can enable a request smuggling attack. The HTTP server code had a flaw that incorrectly understands some requests with multiple transfer-encoding headers to have a chunked payload, when it should have been rejected as illegal. This combined with an upstream HTTP proxy that understands the request payload boundary differently can result in "request smuggling" or "desync attacks". To determine if vulnerable, all these things must be true: 1) Using hyper as an HTTP server (the client is not affected), 2) Using HTTP/1.1 (HTTP/2 does not use transfer-encoding), 3) Using a vulnerable HTTP proxy upstream to hyper. If an upstream proxy correctly rejects the illegal transfer-encoding headers, the desync attack cannot succeed. If there is no proxy upstream of hyper, hyper cannot start the desync attack, as the client will repair the headers before forwarding. This is fixed in versions 0.14.3 and 0.13.10. As a workaround one can take the following options: 1) Reject requests that contain a `transfer-encoding` header, 2) Ensure any upstream proxy handles `transfer-encoding` correctly.
CVE-2021-21445 1 Sap 1 Commerce Cloud 2024-02-04 3.5 LOW 5.4 MEDIUM
SAP Commerce Cloud, versions - 1808, 1811, 1905, 2005, 2011, allows an authenticated attacker to include invalidated data in the HTTP response Content Type header, due to improper input validation, and sent to a Web user. A successful exploitation of this vulnerability may lead to advanced attacks, including cross-site scripting and page hijacking.
CVE-2020-28473 2 Bottlepy, Debian 2 Bottle, Debian Linux 2024-02-04 5.8 MEDIUM 6.8 MEDIUM
The package bottle from 0 and before 0.12.19 are vulnerable to Web Cache Poisoning by using a vector called parameter cloaking. When the attacker can separate query parameters using a semicolon (;), they can cause a difference in the interpretation of the request between the proxy (running with default configuration) and the server. This can result in malicious requests being cached as completely safe ones, as the proxy would usually not see the semicolon as a separator, and therefore would not include it in a cache key of an unkeyed parameter.
CVE-2020-35884 2 Fedoraproject, Tiny-http Project 2 Fedora, Tiny-http 2024-02-04 6.4 MEDIUM 6.5 MEDIUM
An issue was discovered in the tiny_http crate through 2020-06-16 for Rust. HTTP Request smuggling can occur via a malformed Transfer-Encoding header.
CVE-2020-28483 1 Gin-gonic 1 Gin 2024-02-04 5.8 MEDIUM 7.1 HIGH
This affects all versions of package github.com/gin-gonic/gin. When gin is exposed directly to the internet, a client's IP can be spoofed by setting the X-Forwarded-For header.
CVE-2021-23339 1 Lightbend 1 Akka-http 2024-02-04 6.4 MEDIUM 6.5 MEDIUM
This affects all versions before 10.1.14 and from 10.2.0 to 10.2.4 of package com.typesafe.akka:akka-http-core. It allows multiple Transfer-Encoding headers.
CVE-2020-7764 1 Find-my-way Project 1 Find-my-way 2024-02-04 5.0 MEDIUM 7.5 HIGH
This affects the package find-my-way before 2.2.5, from 3.0.0 and before 3.0.5. It accepts the Accept-Version' header by default, and if versioned routes are not being used, this could lead to a denial of service. Accept-Version can be used as an unkeyed header in a cache poisoning attack.
CVE-2021-21295 6 Apache, Debian, Netapp and 3 more 8 Kudu, Zookeeper, Debian Linux and 5 more 2024-02-04 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-2020-8201 3 Fedoraproject, Nodejs, Opensuse 3 Fedora, Node.js, Leap 2024-02-04 5.8 MEDIUM 7.4 HIGH
Node.js < 12.18.4 and < 14.11 can be exploited to perform HTTP desync attacks and deliver malicious payloads to unsuspecting users. The payloads can be crafted by an attacker to hijack user sessions, poison cookies, perform clickjacking, and a multitude of other attacks depending on the architecture of the underlying system. The attack was possible due to a bug in processing of carrier-return symbols in the HTTP header names.
CVE-2019-17565 1 Apache 1 Traffic Server 2024-02-04 7.5 HIGH 9.8 CRITICAL
There is a vulnerability in Apache Traffic Server 6.0.0 to 6.2.3, 7.0.0 to 7.1.8, and 8.0.0 to 8.0.5 with a smuggling attack and chunked encoding. Upgrade to versions 7.1.9 and 8.0.6 or later versions.
CVE-2020-7670 1 Ohler 1 Agoo 2024-02-04 5.0 MEDIUM 7.5 HIGH
agoo prior to 2.14.0 allows request smuggling attacks where agoo is used as a backend and a frontend proxy also being vulnerable. HTTP pipelining issues and request smuggling attacks might be possible due to incorrect Content-Length and Transfer encoding header parsing. It is possible to conduct HTTP request smuggling attacks where `agoo` is used as part of a chain of backend servers due to insufficient `Content-Length` and `Transfer Encoding` parsing.
CVE-2020-1944 1 Apache 1 Traffic Server 2024-02-04 7.5 HIGH 9.8 CRITICAL
There is a vulnerability in Apache Traffic Server 6.0.0 to 6.2.3, 7.0.0 to 7.1.8, and 8.0.0 to 8.0.5 with a smuggling attack and Transfer-Encoding and Content length headers. Upgrade to versions 7.1.9 and 8.0.6 or later versions.
CVE-2020-11077 4 Debian, Fedoraproject, Opensuse and 1 more 4 Debian Linux, Fedora, Leap and 1 more 2024-02-04 5.0 MEDIUM 7.5 HIGH
In Puma (RubyGem) before 4.3.5 and 3.12.6, a client could smuggle a request through a proxy, causing the proxy to send a response back to another unknown client. If the proxy uses persistent connections and the client adds another request in via HTTP pipelining, the proxy may mistake it as the first request's body. Puma, however, would see it as two requests, and when processing the second request, send back a response that the proxy does not expect. If the proxy has reused the persistent connection to Puma to send another request for a different client, the second response from the first client will be sent to the second client. This is a similar but different vulnerability from CVE-2020-11076. The problem has been fixed in Puma 3.12.6 and Puma 4.3.5.
CVE-2020-7659 1 Celluloid 1 Reel 2024-02-04 5.0 MEDIUM 7.5 HIGH
reel through 0.6.1 allows Request Smuggling attacks due to incorrect Content-Length and Transfer encoding header parsing. It is possible to conduct HTTP request smuggling attacks by sending the Content-Length header twice. Furthermore, invalid Transfer Encoding headers were found to be parsed as valid which could be leveraged for TE:CL smuggling attacks. Note: This project is deprecated, and is not maintained any more.
CVE-2019-17559 1 Apache 1 Traffic Server 2024-02-04 7.5 HIGH 9.8 CRITICAL
There is a vulnerability in Apache Traffic Server 6.0.0 to 6.2.3, 7.0.0 to 7.1.8, and 8.0.0 to 8.0.5 with a smuggling attack and scheme parsing. Upgrade to versions 7.1.9 and 8.0.6 or later versions.
CVE-2019-20866 1 Mattermost 1 Mattermost Server 2024-02-04 5.0 MEDIUM 5.3 MEDIUM
An issue was discovered in Mattermost Server before 5.12.0. Use of a Proxy HTTP header, rather than the source address in an IP packet header, for obtaining IP address information was mishandled.
CVE-2020-7655 1 Hive 1 Netius 2024-02-04 4.3 MEDIUM 6.1 MEDIUM
netius prior to 1.17.58 is vulnerable to HTTP Request Smuggling. HTTP pipelining issues and request smuggling attacks might be possible due to incorrect Transfer encoding header parsing which could allow for CL:TE or TE:TE attacks.
CVE-2020-10719 2 Netapp, Redhat 9 Active Iq Unified Manager, Oncommand Insight, Oncommand Workflow Automation and 6 more 2024-02-04 6.4 MEDIUM 6.5 MEDIUM
A flaw was found in Undertow in versions before 2.1.1.Final, regarding the processing of invalid HTTP requests with large chunk sizes. This flaw allows an attacker to take advantage of HTTP request smuggling.
