CVE-2021-31922 1 Pulsesecure 1 Virtual Traffic Manager 2024-02-04 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-2021-32565 2 Apache, Debian 2 Traffic Server, Debian Linux 2024-02-04 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-2021-32715 1 Hyper 1 Hyper 2024-02-04 4.3 MEDIUM 5.3 MEDIUM
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-2021-30180 1 Apache 1 Dubbo 2024-02-04 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-2021-27577 2 Apache, Debian 2 Traffic Server, Debian Linux 2024-02-04 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-2021-36740 5 Debian, Fedoraproject, Varnish-cache and 2 more 5 Debian Linux, Fedora, Varnish Cache and 2 more 2024-02-04 6.4 MEDIUM 6.5 MEDIUM
Varnish Cache, with HTTP/2 enabled, allows request smuggling and VCL authorization bypass via a large Content-Length header for a POST request. This affects Varnish Enterprise 6.0.x before 6.0.8r3, and Varnish Cache 5.x and 6.x before 6.5.2, 6.6.x before 6.6.1, and 6.0 LTS before 6.0.8.
CVE-2021-32598 1 Fortinet 2 Fortianalyzer, Fortimanager 2024-02-04 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-2020-26129 1 Jetbrains 1 Ktor 2024-02-04 6.4 MEDIUM 6.5 MEDIUM
In JetBrains Ktor before 1.4.1, HTTP request smuggling was possible.

An issue was discovered in Squid through 4.13 and 5.x through 5.0.4. Due to improper input validation, it allows a trusted client to perform HTTP Request Smuggling and access services otherwise forbidden by the security controls. This occurs for certain uri_whitespace configuration settings.
CVE-2020-4896 1 Ibm 1 Emptoris Sourcing 2024-02-04 6.4 MEDIUM 6.5 MEDIUM
IBM Emptoris Sourcing 10.1.0, 10.1.1, and 10.1.3 is vulnerable to web cache poisoning, caused by improper input validation by modifying HTTP request headers. IBM X-Force ID: 190987.
CVE-2020-8287 5 Debian, Fedoraproject, Nodejs and 2 more 5 Debian Linux, Fedora, Node.js and 2 more 2024-02-04 6.4 MEDIUM 6.5 MEDIUM
Node.js versions before 10.23.1, 12.20.1, 14.15.4, 15.5.1 allow two copies of a header field in an HTTP request (for example, two Transfer-Encoding header fields). In this case, Node.js identifies the first header field and ignores the second. This can lead to HTTP Request Smuggling.
CVE-2021-20220 2 Netapp, Redhat 3 Active Iq Unified Manager, Oncommand Workflow Automation, Undertow 2024-02-04 5.8 MEDIUM 4.8 MEDIUM
A flaw was found in Undertow. A regression in the fix for CVE-2020-10687 was found. HTTP request smuggling related to CVE-2017-2666 is possible against HTTP/1.x and HTTP/2 due to permitting invalid characters in an HTTP request. This flaw allows an attacker to poison a web-cache, perform an XSS attack, or obtain sensitive information from request other than their own. The highest threat from this vulnerability is to data confidentiality and integrity.
CVE-2021-23336 6 Debian, Djangoproject, Fedoraproject and 3 more 12 Debian Linux, Django, Fedora and 9 more 2024-02-04 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-2020-17509 1 Apache 1 Traffic Server 2024-02-04 4.3 MEDIUM 7.5 HIGH
ATS negative cache option is vulnerable to a cache poisoning attack. If you have this option enabled, please upgrade or disable this feature. Apache Traffic Server versions 7.0.0 to 7.1.11 and 8.0.0 to 8.1.0 are affected.
CVE-2020-25613 2 Fedoraproject, Ruby-lang 3 Fedora, Ruby, Webrick 2024-02-04 5.0 MEDIUM 7.5 HIGH
An issue was discovered in Ruby through 2.5.8, 2.6.x through 2.6.6, and 2.7.x through 2.7.1. WEBrick, a simple HTTP server bundled with Ruby, had not checked the transfer-encoding header value rigorously. An attacker may potentially exploit this issue to bypass a reverse proxy (which also has a poor header check), which may lead to an HTTP Request Smuggling attack.
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.
