CVE-2020-10112 1 Citrix 1 Gateway Firmware 2024-11-21 5.8 MEDIUM 5.4 MEDIUM
Citrix Gateway 11.1, 12.0, and 12.1 allows Cache Poisoning. NOTE: Citrix disputes this as not a vulnerability. By default, Citrix ADC only caches static content served under certain URL paths for Citrix Gateway usage. No dynamic content is served under these paths, which implies that those cached pages would not change based on parameter values. All other data traffic going through Citrix Gateway are NOT cached by default
CVE-2020-10111 1 Citrix 1 Gateway Firmware 2024-11-21 5.0 MEDIUM 7.5 HIGH
Citrix Gateway 11.1, 12.0, and 12.1 has an Inconsistent Interpretation of HTTP Requests. NOTE: Citrix disputes the reported behavior as not a security issue. Citrix ADC only caches HTTP/1.1 traffic for performance optimization
CVE-2020-10109 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2024-11-21 7.5 HIGH 9.8 CRITICAL
In Twisted Web through 19.10.0, there was an HTTP request splitting vulnerability. When presented with a content-length and a chunked encoding header, the content-length took precedence and the remainder of the request body was interpreted as a pipelined request.
CVE-2020-10108 5 Canonical, Debian, Fedoraproject and 2 more 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2024-11-21 7.5 HIGH 9.8 CRITICAL
In Twisted Web through 19.10.0, there was an HTTP request splitting vulnerability. When presented with two content-length headers, it ignored the first header. When the second content-length value was set to zero, the request body was interpreted as a pipelined request.
CVE-2019-20866 1 Mattermost 1 Mattermost Server 2024-11-21 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-2019-20445 6 Apache, Canonical, Debian and 3 more 8 Spark, Ubuntu Linux, Debian Linux and 5 more 2024-11-21 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-2019-20444 5 Canonical, Debian, Fedoraproject and 2 more 7 Ubuntu Linux, Debian Linux, Fedora and 4 more 2024-11-21 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-2019-20372 5 Apple, Canonical, F5 and 2 more 5 Xcode, Ubuntu Linux, Nginx and 2 more 2024-11-21 4.3 MEDIUM 5.3 MEDIUM
NGINX before 1.17.7, with certain error_page configurations, allows HTTP request smuggling, as demonstrated by the ability of an attacker to read unauthorized web pages in environments where NGINX is being fronted by a load balancer.
CVE-2019-19326 1 Silverstripe 1 Silverstripe 2024-11-21 4.3 MEDIUM 5.9 MEDIUM
Silverstripe CMS sites through 4.4.4 which have opted into HTTP Cache Headers on responses served by the framework's HTTP layer can be vulnerable to web cache poisoning. Through modifying the X-Original-Url and X-HTTP-Method-Override headers, responses with malicious HTTP headers can return unexpected responses to other consumers of this cached response. Most other headers associated with web cache poisoning are already disabled through request hostname forgery whitelists.
CVE-2019-19223 1 Dlink 2 Dsl-2680, Dsl-2680 Firmware 2024-11-21 7.8 HIGH 7.5 HIGH
A Broken Access Control vulnerability in the D-Link DSL-2680 web administration interface (Firmware EU_1.03) allows an attacker to reboot the router by submitting a reboot.html GET request without being authenticated on the admin interface.
CVE-2019-18678 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2024-11-21 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-2019-18277 1 Haproxy 1 Haproxy 2024-11-21 4.3 MEDIUM 7.5 HIGH
A flaw was found in HAProxy before 2.0.6. In legacy mode, messages featuring a transfer-encoding header missing the "chunked" value were not being correctly rejected. The impact was limited but if combined with the "http-reuse always" setting, it could be used to help construct an HTTP request smuggling attack against a vulnerable component employing a lenient parser that would ignore the content-length header as soon as it saw a transfer-encoding one (even if not entirely valid according to the specification).
CVE-2019-17569 5 Apache, Debian, Netapp and 2 more 16 Tomcat, Tomee, Debian Linux and 13 more 2024-11-21 5.8 MEDIUM 4.8 MEDIUM
The refactoring present in Apache Tomcat 9.0.28 to 9.0.30, 8.5.48 to 8.5.50 and 7.0.98 to 7.0.99 introduced a regression. The result of the regression was that invalid Transfer-Encoding headers were incorrectly processed leading to a possibility of HTTP Request Smuggling if Tomcat was located behind a reverse proxy that incorrectly handled the invalid Transfer-Encoding header in a particular manner. Such a reverse proxy is considered unlikely.
CVE-2019-17567 3 Apache, Fedoraproject, Oracle 5 Http Server, Fedora, Enterprise Manager Ops Center and 2 more 2024-11-21 5.0 MEDIUM 5.3 MEDIUM
Apache HTTP Server versions 2.4.6 to 2.4.46 mod_proxy_wstunnel configured on an URL that is not necessarily Upgraded by the origin server was tunneling the whole connection regardless, thus allowing for subsequent requests on the same connection to pass through with no HTTP validation, authentication or authorization possibly configured.
CVE-2019-17565 2 Apache, Debian 2 Traffic Server, Debian Linux 2024-11-21 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-2019-17559 2 Apache, Debian 2 Traffic Server, Debian Linux 2024-11-21 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-2019-16869 4 Canonical, Debian, Netty and 1 more 5 Ubuntu Linux, Debian Linux, Netty and 2 more 2024-11-21 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-2019-16792 3 Agendaless, Debian, Oracle 3 Waitress, Debian Linux, Communications Cloud Native Core Network Function Cloud Native Environment 2024-11-21 5.0 MEDIUM 7.1 HIGH
Waitress through version 1.3.1 allows request smuggling by sending the Content-Length header twice. Waitress would header fold a double Content-Length header and due to being unable to cast the now comma separated value to an integer would set the Content-Length to 0 internally. If two Content-Length headers are sent in a single request, Waitress would treat the request as having no body, thereby treating the body of the request as a new request in HTTP pipelining. This issue is fixed in Waitress 1.4.0.
CVE-2019-16789 5 Agendaless, Debian, Fedoraproject and 2 more 5 Waitress, Debian Linux, Fedora and 2 more 2024-11-21 6.4 MEDIUM 7.1 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-2019-16786 5 Agendaless, Debian, Fedoraproject and 2 more 5 Waitress, Debian Linux, Fedora and 2 more 2024-11-21 5.0 MEDIUM 7.1 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.
