| CVE-2020-25613 | 3 Fedoraproject, Redhat, Ruby-lang | 7 Fedora, Enterprise Linux, Rhel E4s and 4 more | 2024-11-21 | 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-2020-25097 | 5 Debian, Fedoraproject, Netapp and 2 more | 6 Debian Linux, Fedora, Cloud Manager and 3 more | 2024-11-21 | 8.6 High |
| 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-2020-1944 | 2 Apache, Debian | 2 Traffic Server, Debian Linux | 2024-11-21 | 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-2020-1935 | 7 Apache, Canonical, Debian and 4 more | 25 Tomcat, Ubuntu Linux, Debian Linux and 22 more | 2024-11-21 | 4.8 Medium |
| In Apache Tomcat 9.0.0.M1 to 9.0.30, 8.5.0 to 8.5.50 and 7.0.0 to 7.0.99 the HTTP header parsing code used an approach to end-of-line parsing that allowed some invalid HTTP headers to be parsed as valid. This led 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-2020-17509 | 1 Apache | 1 Traffic Server | 2024-11-21 | 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-2020-15811 | 6 Canonical, Debian, Fedoraproject and 3 more | 8 Ubuntu Linux, Debian Linux, Fedora and 5 more | 2024-11-21 | 6.5 Medium |
| An issue was discovered in Squid before 4.13 and 5.x before 5.0.4. Due to incorrect data validation, HTTP Request Splitting attacks may succeed against HTTP and HTTPS traffic. This leads to cache poisoning. This allows any client, including browser scripts, to bypass local security and poison the browser cache and any downstream caches with content from an arbitrary source. Squid uses a string search instead of parsing the Transfer-Encoding header to find chunked encoding. This allows an attacker to hide a second request inside Transfer-Encoding: it is interpreted by Squid as chunked and split out into a second request delivered upstream. Squid will then deliver two distinct responses to the client, corrupting any downstream caches. | ||||
| CVE-2020-15810 | 6 Canonical, Debian, Fedoraproject and 3 more | 8 Ubuntu Linux, Debian Linux, Fedora and 5 more | 2024-11-21 | 6.5 Medium |
| An issue was discovered in Squid before 4.13 and 5.x before 5.0.4. Due to incorrect data validation, HTTP Request Smuggling attacks may succeed against HTTP and HTTPS traffic. This leads to cache poisoning. This allows any client, including browser scripts, to bypass local security and poison the proxy cache and any downstream caches with content from an arbitrary source. When configured for relaxed header parsing (the default), Squid relays headers containing whitespace characters to upstream servers. When this occurs as a prefix to a Content-Length header, the frame length specified will be ignored by Squid (allowing for a conflicting length to be used from another Content-Length header) but relayed upstream. | ||||
| CVE-2020-15049 | 3 Fedoraproject, Redhat, Squid-cache | 3 Fedora, Enterprise Linux, Squid | 2024-11-21 | 9.9 Critical |
| An issue was discovered in http/ContentLengthInterpreter.cc in Squid before 4.12 and 5.x before 5.0.3. A Request Smuggling and Poisoning attack can succeed against the HTTP cache. The client sends an HTTP request with a Content-Length header containing "+\ "-" or an uncommon shell whitespace character prefix to the length field-value. | ||||
| CVE-2020-11993 | 8 Apache, Canonical, Debian and 5 more | 16 Http Server, Ubuntu Linux, Debian Linux and 13 more | 2024-11-21 | 7.5 High |
| Apache HTTP Server versions 2.4.20 to 2.4.43 When trace/debug was enabled for the HTTP/2 module and on certain traffic edge patterns, logging statements were made on the wrong connection, causing concurrent use of memory pools. Configuring the LogLevel of mod_http2 above "info" will mitigate this vulnerability for unpatched servers. | ||||
| CVE-2020-11724 | 2 Debian, Openresty | 2 Debian Linux, Openresty | 2024-11-21 | 7.5 High |
| An issue was discovered in OpenResty before 1.15.8.4. ngx_http_lua_subrequest.c allows HTTP request smuggling, as demonstrated by the ngx.location.capture API. | ||||
| CVE-2020-11506 | 1 Gitlab | 1 Gitlab | 2024-11-21 | 7.5 High |
| An issue was discovered in GitLab 10.7.0 and later through 12.9.2. A Workhorse bypass could lead to job artifact uploads and file disclosure (Exposure of Sensitive Information) via request smuggling. | ||||
| CVE-2020-11505 | 1 Gitlab | 1 Gitlab | 2024-11-21 | 7.5 High |
| An issue was discovered in GitLab Community Edition (CE) and Enterprise Edition (EE) before 12.7.9, 12.8.x before 12.8.9, and 12.9.x before 12.9.3. A Workhorse bypass could lead to NuGet package and file disclosure (Exposure of Sensitive Information) via request smuggling. | ||||
| CVE-2020-11077 | 4 Debian, Fedoraproject, Opensuse and 1 more | 4 Debian Linux, Fedora, Leap and 1 more | 2024-11-21 | 6.8 Medium |
| 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-2020-11076 | 3 Debian, Fedoraproject, Puma | 3 Debian Linux, Fedora, Puma | 2024-11-21 | 7.5 High |
| In Puma (RubyGem) before 4.3.4 and 3.12.5, an attacker could smuggle an HTTP response, by using an invalid transfer-encoding header. The problem has been fixed in Puma 3.12.5 and Puma 4.3.4. | ||||
| CVE-2020-10719 | 2 Netapp, Redhat | 12 Active Iq Unified Manager, Oncommand Insight, Oncommand Workflow Automation and 9 more | 2024-11-21 | 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. | ||||
| CVE-2020-10687 | 1 Redhat | 6 Enterprise Linux, Jboss Enterprise Application Platform, Jboss Fuse and 3 more | 2024-11-21 | 4.8 Medium |
| A flaw was discovered in all versions of Undertow before Undertow 2.2.0.Final, where 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. | ||||
| CVE-2020-10112 | 1 Citrix | 1 Gateway Firmware | 2024-11-21 | 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 | 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-2019-20866 | 1 Mattermost | 1 Mattermost Server | 2024-11-21 | 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 | 20 Spark, Ubuntu Linux, Debian Linux and 17 more | 2024-11-21 | 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. | ||||
