CVE-2020-35884 2 Fedoraproject, Tiny-http Project 2 Fedora, Tiny-http 2024-08-04 6.5 Medium
An issue was discovered in the tiny_http crate through 2020-06-16 for Rust. HTTP Request smuggling can occur via a malformed Transfer-Encoding header.
CVE-2020-28361 1 Kamailio 1 Kamailio 2024-08-04 5.4 Medium
Kamailio before 5.4.0, as used in Sip Express Router (SER) in Sippy Softswitch 4.5 through 5.2 and other products, allows a bypass of a header-removal protection mechanism via whitespace characters. This occurs in the remove_hf function in the Kamailio textops module. Particular use of remove_hf in Sippy Softswitch may allow skilled attacker having a valid credential in the system to disrupt internal call start/duration accounting mechanisms leading potentially to a loss of revenue.
CVE-2020-26281 1 Rust-lang 1 Async-h1 2024-08-04 6.8 Medium
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-2020-26129 1 Jetbrains 1 Ktor 2024-08-04 6.5 Medium
In JetBrains Ktor before 1.4.1, HTTP request smuggling was possible.
CVE-2020-25613 3 Fedoraproject, Redhat, Ruby-lang 7 Fedora, Enterprise Linux, Rhel E4s and 4 more 2024-08-04 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 2024-08-04 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-2020-17509 1 Apache 1 Traffic Server 2024-08-04 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 2024-08-04 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 2024-08-04 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 2024-08-04 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 2024-08-04 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 2024-08-04 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-2020-11505 1 Gitlab 1 Gitlab 2024-08-04 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-2020-11506 1 Gitlab 1 Gitlab 2024-08-04 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-2020-11076 3 Debian, Fedoraproject, Puma 3 Debian Linux, Fedora, Puma 2024-08-04 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-2020-11077 4 Debian, Fedoraproject, Opensuse and 1 more 4 Debian Linux, Fedora, Leap and 1 more 2024-08-04 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-2020-10112 1 Citrix 1 Gateway Firmware 2024-08-04 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 2024-08-04 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-2020-10719 2 Netapp, Redhat 12 Active Iq Unified Manager, Oncommand Insight, Oncommand Workflow Automation and 9 more 2024-08-04 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 2024-08-04 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.
