CVE-2019-18678 | 4 Canonical, Debian, Fedoraproject and 1 more | 4 Ubuntu Linux, Debian Linux, Fedora and 1 more | 2023-11-07 | 5.0 MEDIUM | 5.3 MEDIUM |
An issue was discovered in Squid 3.x and 4.x through 4.8. It allows attackers to smuggle HTTP requests through frontend software to a Squid instance that splits the HTTP Request pipeline differently. The resulting Response messages corrupt caches (between a client and Squid) with attacker-controlled content at arbitrary URLs. Effects are isolated to software between the attacker client and Squid. There are no effects on Squid itself, nor on any upstream servers. The issue is related to a request header containing whitespace between a header name and a colon. | |||||
CVE-2019-16789 | 5 Agendaless, Debian, Fedoraproject and 2 more | 5 Waitress, Debian Linux, Fedora and 2 more | 2023-11-07 | 6.4 MEDIUM | 8.2 HIGH |
In Waitress through version 1.4.0, if a proxy server is used in front of waitress, an invalid request may be sent by an attacker that bypasses the front-end and is parsed differently by waitress leading to a potential for HTTP request smuggling. Specially crafted requests containing special whitespace characters in the Transfer-Encoding header would get parsed by Waitress as being a chunked request, but a front-end server would use the Content-Length instead as the Transfer-Encoding header is considered invalid due to containing invalid characters. If a front-end server does HTTP pipelining to a backend Waitress server this could lead to HTTP request splitting which may lead to potential cache poisoning or unexpected information disclosure. This issue is fixed in Waitress 1.4.1 through more strict HTTP field validation. | |||||
CVE-2019-16785 | 5 Agendaless, Debian, Fedoraproject and 2 more | 5 Waitress, Debian Linux, Fedora and 2 more | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
Waitress through version 1.3.1 implemented a "MAY" part of the RFC7230 which states: "Although the line terminator for the start-line and header fields is the sequence CRLF, a recipient MAY recognize a single LF as a line terminator and ignore any preceding CR." Unfortunately if a front-end server does not parse header fields with an LF the same way as it does those with a CRLF it can lead to the front-end and the back-end server parsing the same HTTP message in two different ways. This can lead to a potential for HTTP request smuggling/splitting whereby Waitress may see two requests while the front-end server only sees a single HTTP message. This issue is fixed in Waitress 1.4.0. | |||||
CVE-2019-16276 | 6 Debian, Fedoraproject, Golang and 3 more | 9 Debian Linux, Fedora, Go and 6 more | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
Go before 1.12.10 and 1.13.x before 1.13.1 allow HTTP Request Smuggling. | |||||
CVE-2019-16786 | 5 Agendaless, Debian, Fedoraproject and 2 more | 5 Waitress, Debian Linux, Fedora and 2 more | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
Waitress through version 1.3.1 would parse the Transfer-Encoding header and only look for a single string value, if that value was not chunked it would fall through and use the Content-Length header instead. According to the HTTP standard Transfer-Encoding should be a comma separated list, with the inner-most encoding first, followed by any further transfer codings, ending with chunked. Requests sent with: "Transfer-Encoding: gzip, chunked" would incorrectly get ignored, and the request would use a Content-Length header instead to determine the body size of the HTTP message. This could allow for Waitress to treat a single request as multiple requests in the case of HTTP pipelining. This issue is fixed in Waitress 1.4.0. | |||||
CVE-2018-8004 | 2 Apache, Debian | 2 Traffic Server, Debian Linux | 2023-11-07 | 4.0 MEDIUM | 6.5 MEDIUM |
There are multiple HTTP smuggling and cache poisoning issues when clients making malicious requests interact with Apache Traffic Server (ATS). This affects versions 6.0.0 to 6.2.2 and 7.0.0 to 7.1.3. To resolve this issue users running 6.x should upgrade to 6.2.3 or later versions and 7.x users should upgrade to 7.1.4 or later versions. | |||||
CVE-2019-0197 | 6 Apache, Canonical, Fedoraproject and 3 more | 12 Http Server, Ubuntu Linux, Fedora and 9 more | 2023-11-07 | 4.9 MEDIUM | 4.2 MEDIUM |
A vulnerability was found in Apache HTTP Server 2.4.34 to 2.4.38. When HTTP/2 was enabled for a http: host or H2Upgrade was enabled for h2 on a https: host, an Upgrade request from http/1.1 to http/2 that was not the first request on a connection could lead to a misconfiguration and crash. Server that never enabled the h2 protocol or that only enabled it for https: and did not set "H2Upgrade on" are unaffected by this issue. | |||||
CVE-2017-7657 | 5 Debian, Eclipse, Hp and 2 more | 18 Debian Linux, Jetty, Xp P9000 and 15 more | 2023-11-07 | 7.5 HIGH | 9.8 CRITICAL |
In Eclipse Jetty, versions 9.2.x and older, 9.3.x (all configurations), and 9.4.x (non-default configuration with RFC2616 compliance enabled), transfer-encoding chunks are handled poorly. The chunk length parsing was vulnerable to an integer overflow. Thus a large chunk size could be interpreted as a smaller chunk size and content sent as chunk body could be interpreted as a pipelined request. If Jetty was deployed behind an intermediary that imposed some authorization and that intermediary allowed arbitrarily large chunks to be passed on unchanged, then this flaw could be used to bypass the authorization imposed by the intermediary as the fake pipelined request would not be interpreted by the intermediary as a request. | |||||
CVE-2017-7658 | 5 Debian, Eclipse, Hp and 2 more | 20 Debian Linux, Jetty, Xp P9000 and 17 more | 2023-11-07 | 7.5 HIGH | 9.8 CRITICAL |
In Eclipse Jetty Server, versions 9.2.x and older, 9.3.x (all non HTTP/1.x configurations), and 9.4.x (all HTTP/1.x configurations), when presented with two content-lengths headers, Jetty ignored the second. When presented with a content-length and a chunked encoding header, the content-length was ignored (as per RFC 2616). If an intermediary decided on the shorter length, but still passed on the longer body, then body content could be interpreted by Jetty as a pipelined request. If the intermediary was imposing authorization, the fake pipelined request would bypass that authorization. | |||||
CVE-2023-30910 | 1 Hpe | 6 Msa 1060 Storage, Msa 1060 Storage Firmware, Msa 2060 Storage and 3 more | 2023-10-13 | N/A | 5.4 MEDIUM |
HPE MSA Controller prior to version IN210R004 could be remotely exploited to allow inconsistent interpretation of HTTP requests. | |||||
CVE-2023-40175 | 1 Puma | 1 Puma | 2023-08-24 | N/A | 9.8 CRITICAL |
Puma is a Ruby/Rack web server built for parallelism. Prior to versions 6.3.1 and 5.6.7, puma exhibited incorrect behavior when parsing chunked transfer encoding bodies and zero-length Content-Length headers in a way that allowed HTTP request smuggling. Severity of this issue is highly dependent on the nature of the web site using puma is. This could be caused by either incorrect parsing of trailing fields in chunked transfer encoding bodies or by parsing of blank/zero-length Content-Length headers. Both issues have been addressed and this vulnerability has been fixed in versions 6.3.1 and 5.6.7. Users are advised to upgrade. There are no known workarounds for this vulnerability. | |||||
CVE-2023-40225 | 1 Haproxy | 1 Haproxy | 2023-08-18 | N/A | 7.2 HIGH |
HAProxy through 2.0.32, 2.1.x and 2.2.x through 2.2.30, 2.3.x and 2.4.x through 2.4.23, 2.5.x and 2.6.x before 2.6.15, 2.7.x before 2.7.10, and 2.8.x before 2.8.2 forwards empty Content-Length headers, violating RFC 9110 section 8.6. In uncommon cases, an HTTP/1 server behind HAProxy may interpret the payload as an extra request. | |||||
CVE-2023-38697 | 1 Socketry | 1 Protocol-http1 | 2023-08-10 | N/A | 5.3 MEDIUM |
protocol-http1 provides a low-level implementation of the HTTP/1 protocol. RFC 9112 Section 7.1 defined the format of chunk size, chunk data and chunk extension. The value of Content-Length header should be a string of 0-9 digits, the chunk size should be a string of hex digits and should split from chunk data using CRLF, and the chunk extension shouldn't contain any invisible character. However, Falcon has following behaviors while disobey the corresponding RFCs: accepting Content-Length header values that have `+` prefix, accepting Content-Length header values that written in hexadecimal with `0x` prefix, accepting `0x` and `+` prefixed chunk size, and accepting LF in chunk extension. This behavior can lead to desync when forwarding through multiple HTTP parsers, potentially results in HTTP request smuggling and firewall bypassing. This issue is fixed in `protocol-http1` v0.15.1. There are no known workarounds. | |||||
CVE-2023-34037 | 1 Vmware | 1 Horizon Client | 2023-08-09 | N/A | 5.3 MEDIUM |
VMware Horizon Server contains a HTTP request smuggling vulnerability. A malicious actor with network access may be able to perform HTTP smuggle requests. | |||||
CVE-2021-46825 | 1 Broadcom | 2 Advanced Secure Gateway, Proxysg | 2023-08-08 | 6.4 MEDIUM | 9.1 CRITICAL |
Symantec Advanced Secure Gateway (ASG) and ProxySG are susceptible to an HTTP desync vulnerability. When a remote unauthenticated attacker and other web clients communicate through the proxy with the same web server, the attacker can send crafted HTTP requests and cause the proxy to forward web server responses to unintended clients.

CVE-2022-38114 | 1 Solarwinds | 1 Security Event Manager | 2023-08-03 | N/A | 6.1 MEDIUM |
This vulnerability occurs when a web server fails to correctly process the Content-Length of POST requests. This can lead to HTTP request smuggling or XSS. | |||||
CVE-2023-35944 | 1 Envoyproxy | 1 Envoy | 2023-08-02 | N/A | 5.3 MEDIUM |
Envoy is an open source edge and service proxy designed for cloud-native applications. Envoy allows mixed-case schemes in HTTP/2, however, some internal scheme checks are case-sensitive. Prior to versions 1.27.0, 1.26.4, 1.25.9, 1.24.10, and 1.23.12, this can lead to the rejection of requests with mixed-case schemes such as `htTp` or `htTps`, or the bypassing of some requests such as `https` in unencrypted connections. With a fix in versions 1.27.0, 1.26.4, 1.25.9, 1.24.10, and 1.23.12, Envoy will now lowercase scheme values by default, and change the internal scheme checks that were case-sensitive to be case-insensitive. There are no known workarounds for this issue. | |||||
CVE-2022-32214 | 4 Debian, Llhttp, Nodejs and 1 more | 4 Debian Linux, Llhttp, Node.js and 1 more | 2023-07-19 | N/A | 6.5 MEDIUM |
The llhttp parser <v14.20.1, <v16.17.1 and <v18.9.1 in the http module in Node.js does not strictly use the CRLF sequence to delimit HTTP requests. This can lead to HTTP Request Smuggling (HRS). | |||||
CVE-2023-33987 | 1 Sap | 1 Web Dispatcher | 2023-07-18 | N/A | 9.4 CRITICAL |
An unauthenticated attacker in SAP Web Dispatcher - versions WEBDISP 7.49, WEBDISP 7.53, WEBDISP 7.54, WEBDISP 7.77, WEBDISP 7.81, WEBDISP 7.85, WEBDISP 7.88, WEBDISP 7.89, WEBDISP 7.90, KERNEL 7.49, KERNEL 7.53, KERNEL 7.54 KERNEL 7.77, KERNEL 7.81, KERNEL 7.85, KERNEL 7.88, KERNEL 7.89, KERNEL 7.90, KRNL64NUC 7.49, KRNL64UC 7.49, KRNL64UC 7.53, HDB 2.00, XS_ADVANCED_RUNTIME 1.00, SAP_EXTENDED_APP_SERVICES 1, can submit a malicious crafted request over a network to a front-end server which may, over several attempts, result in a back-end server confusing the boundaries of malicious and legitimate messages. This can result in the back-end server executing a malicious payload which can be used to read or modify information on the server or make it temporarily unavailable. | |||||
CVE-2022-25763 | 3 Apache, Debian, Fedoraproject | 3 Traffic Server, Debian Linux, Fedora | 2023-07-12 | N/A | 7.5 HIGH |
