CVE-2021-33683 1 Sap 2 Internet Communication Manager, Web Dispatcher 2024-11-21 4.0 MEDIUM 4.3 MEDIUM
SAP Web Dispatcher and Internet Communication Manager (ICM), versions - KRNL32NUC 7.21, 7.21EXT, 7.22, 7.22EXT, KRNL32UC 7.21, 7.21EXT, 7.22, 7.22EXT, KRNL64NUC 7.21, 7.21EXT, 7.22, 7.22EXT, 7.49, KRNL64UC 7.21, 7.21EXT, 7.22, 7.22EXT, 7.49, 7.53, 7.73, WEBDISP 7.53, 7.73, 7.77, 7.81, 7.82, 7.83, KERNEL 7.21, 7.22, 7.49, 7.53, 7.73, 7.77, 7.81, 7.82, 7.83, process invalid HTTP header. The incorrect handling of the invalid Transfer-Encoding header in a particular manner leads to a possibility of HTTP Request Smuggling attack. An attacker could exploit this vulnerability to bypass web application firewall protection, divert sensitive data such as customer requests, session credentials, etc.
CVE-2021-33056 1 Linphone 1 Belle-sip 2024-11-21 5.0 MEDIUM 7.5 HIGH
Belledonne Belle-sip before 4.5.20, as used in Linphone and other products, can crash via an invalid From header in a SIP message.
CVE-2021-33037 4 Apache, Debian, Mcafee and 1 more 22 Tomcat, Tomee, Debian Linux and 19 more 2024-11-21 5.0 MEDIUM 5.3 MEDIUM
Apache Tomcat 10.0.0-M1 to 10.0.6, 9.0.0.M1 to 9.0.46 and 8.5.0 to 8.5.66 did not correctly parse the HTTP transfer-encoding request header in some circumstances leading to the possibility to request smuggling when used with a reverse proxy. Specifically: - Tomcat incorrectly ignored the transfer encoding header if the client declared it would only accept an HTTP/1.0 response; - Tomcat honoured the identify encoding; and - Tomcat did not ensure that, if present, the chunked encoding was the final encoding.
CVE-2021-32715 1 Hyper 1 Hyper 2024-11-21 4.3 MEDIUM 3.1 LOW
hyper is an HTTP library for rust. hyper's HTTP/1 server code had a flaw that incorrectly parses and accepts requests with a `Content-Length` header with a prefixed plus sign, when it should have been rejected as illegal. This combined with an upstream HTTP proxy that doesn't parse such `Content-Length` headers, but forwards them, can result in "request smuggling" or "desync attacks". The flaw exists in all prior versions of hyper prior to 0.14.10, if built with `rustc` v1.5.0 or newer. The vulnerability is patched in hyper version 0.14.10. Two workarounds exist: One may reject requests manually that contain a plus sign prefix in the `Content-Length` header or ensure any upstream proxy handles `Content-Length` headers with a plus sign prefix.
CVE-2021-32598 1 Fortinet 2 Fortianalyzer, Fortimanager 2024-11-21 4.0 MEDIUM 4.3 MEDIUM
An improper neutralization of CRLF sequences in HTTP headers ('HTTP Response Splitting') vulnerability In FortiManager and FortiAnalyzer GUI 7.0.0, 6.4.6 and below, 6.2.8 and below, 6.0.11 and below, 5.6.11 and below may allow an authenticated and remote attacker to perform an HTTP request splitting attack which gives attackers control of the remaining headers and body of the response.
CVE-2021-32565 2 Apache, Debian 2 Traffic Server, Debian Linux 2024-11-21 5.0 MEDIUM 7.5 HIGH
Invalid values in the Content-Length header sent to Apache Traffic Server allows an attacker to smuggle requests. This issue affects Apache Traffic Server 7.0.0 to 7.1.12, 8.0.0 to 8.1.1, 9.0.0 to 9.0.1.
CVE-2021-31923 1 Pingidentity 1 Pingaccess 2024-11-21 5.0 MEDIUM 5.3 MEDIUM
Ping Identity PingAccess before 5.3.3 allows HTTP request smuggling via header manipulation.
CVE-2021-31922 1 Pulsesecure 1 Virtual Traffic Manager 2024-11-21 5.0 MEDIUM 7.5 HIGH
An HTTP Request Smuggling vulnerability in Pulse Secure Virtual Traffic Manager before 21.1 could allow an attacker to smuggle an HTTP request through an HTTP/2 Header. This vulnerability is resolved in 21.1, 20.3R1, 20.2R1, 20.1R2, 19.2R4, and 18.2R3.
CVE-2021-30180 1 Apache 1 Dubbo 2024-11-21 6.8 MEDIUM 9.8 CRITICAL
Apache Dubbo prior to 2.7.9 support Tag routing which will enable a customer to route the request to the right server. These rules are used by the customers when making a request in order to find the right endpoint. When parsing these YAML rules, Dubbo customers may enable calling arbitrary constructors.
CVE-2021-29991 1 Mozilla 2 Firefox, Thunderbird 2024-11-21 5.8 MEDIUM 8.1 HIGH
Firefox incorrectly accepted a newline in a HTTP/3 header, interpretting it as two separate headers. This allowed for a header splitting attack against servers using HTTP/3. This vulnerability affects Firefox < 91.0.1 and Thunderbird < 91.0.1.
CVE-2021-27577 2 Apache, Debian 2 Traffic Server, Debian Linux 2024-11-21 5.0 MEDIUM 7.5 HIGH
Incorrect handling of url fragment vulnerability of Apache Traffic Server allows an attacker to poison the cache. This issue affects Apache Traffic Server 7.0.0 to 7.1.12, 8.0.0 to 8.1.1, 9.0.0 to 9.0.1.
CVE-2021-25762 1 Jetbrains 1 Ktor 2024-11-21 5.0 MEDIUM 5.3 MEDIUM
In JetBrains Ktor before 1.4.3, HTTP Request Smuggling was possible.
CVE-2021-25220 5 Fedoraproject, Isc, Juniper and 2 more 48 Fedora, Bind, Junos and 45 more 2024-11-21 4.0 MEDIUM 6.8 MEDIUM
BIND 9.11.0 -> 9.11.36 9.12.0 -> 9.16.26 9.17.0 -> 9.18.0 BIND Supported Preview Editions: 9.11.4-S1 -> 9.11.36-S1 9.16.8-S1 -> 9.16.26-S1 Versions of BIND 9 earlier than those shown - back to 9.1.0, including Supported Preview Editions - are also believed to be affected but have not been tested as they are EOL. The cache could become poisoned with incorrect records leading to queries being made to the wrong servers, which might also result in false information being returned to clients.
CVE-2021-23339 1 Lightbend 1 Akka-http 2024-11-21 6.4 MEDIUM 5.0 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-2021-23336 6 Debian, Djangoproject, Fedoraproject and 3 more 12 Debian Linux, Django, Fedora and 9 more 2024-11-21 4.0 MEDIUM 5.9 MEDIUM
The package python/cpython from 0 and before 3.6.13, from 3.7.0 and before 3.7.10, from 3.8.0 and before 3.8.8, from 3.9.0 and before 3.9.2 are vulnerable to Web Cache Poisoning via urllib.parse.parse_qsl and urllib.parse.parse_qs 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-2021-22960 3 Debian, Llhttp, Oracle 3 Debian Linux, Llhttp, Graalvm 2024-11-21 5.8 MEDIUM 6.5 MEDIUM
The parse function in llhttp < 2.1.4 and < 6.0.6. ignores chunk extensions when parsing the body of chunked requests. This leads to HTTP Request Smuggling (HRS) under certain conditions.
CVE-2021-22959 3 Debian, Llhttp, Oracle 3 Debian Linux, Llhttp, Graalvm 2024-11-21 6.4 MEDIUM 6.5 MEDIUM
The parser in accepts requests with a space (SP) right after the header name before the colon. This can lead to HTTP Request Smuggling (HRS) in llhttp < v2.1.4 and < v6.0.6.
CVE-2021-22293 1 Huawei 4 Campusinsight, Manageone, Taurus-al00a and 1 more 2024-11-21 5.0 MEDIUM 7.5 HIGH
Some Huawei products have an inconsistent interpretation of HTTP requests vulnerability. Attackers can exploit this vulnerability to cause information leak. Affected product versions include: CampusInsight versions V100R019C10; ManageOne versions 6.5.1.1, 6.5.1.SPC100, 6.5.1.SPC200, 6.5.1RC1, 6.5.1RC2, 8.0.RC2. Affected product versions include: Taurus-AL00A versions 10.0.0.1(C00E1R1P1).
CVE-2021-21445 1 Sap 1 Commerce Cloud 2024-11-21 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-2021-21409 5 Debian, Netapp, Netty and 2 more 18 Debian Linux, Oncommand Api Services, Oncommand Workflow Automation and 15 more 2024-11-21 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.
