An issue was discovered in Varnish Cache 7.x before 7.1.2 and 7.2.x before 7.2.1. A request smuggling attack can be performed on Varnish Cache servers by requesting that certain headers are made hop-by-hop, preventing the Varnish Cache servers from forwarding critical headers to the backend...

BIT-TOMCAT-2023-45648 Apache Tomcat: Trailer header parsing too lenient

Improper Input Validation vulnerability in Apache Tomcat.Tomcat from 11.0.0 through 11.0.0, from 10.1.0 through 10.1.13, from 9.0.0 through 9.0.81 and from 8.5.0 through 8.5.93 did not correctly parse HTTP trailer headers. A specially crafted, invalid trailer header could cause Tomcat to treat a...

BIT-TOMCAT-2023-46589 Apache Tomcat: HTTP request smuggling via malformed trailer headers

Improper Input Validation vulnerability in Apache Tomcat.Tomcat from 11.0.0 through 11.0.0, from 10.1.0 through 10.1.15, from 9.0.0 through 9.0.82 and from 8.5.0 through 8.5.95 did not correctly parse HTTP trailer headers. A trailer header that exceeded the header size limit could cause Tomcat to...

BIT-NODE-2020-8287

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...

BIT-RUBY-2020-25613

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 po...

The llhttp parser v14.20.1, v16.17.1 and v18.9.1 in the http module in Node.js does not correctly parse and validate Transfer-Encoding headers and can lead to HTTP Request Smuggling HRS...

BIT-NODE-2022-32214

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...

BIT-NODE-2022-32215

The llhttp parser v14.20.1, v16.17.1 and v18.9.1 in the http module in Node.js does not correctly handle multi-line Transfer-Encoding headers. This can lead to HTTP Request Smuggling HRS...

BIT-GOLANG-2022-1705 Improper sanitization of Transfer-Encoding headers in net/http

Acceptance of some invalid Transfer-Encoding headers in the HTTP/1 client in net/http before Go 1.17.12 and Go 1.18.4 allows HTTP request smuggling if combined with an intermediate server that also improperly fails to reject the header as invalid...

BIT-NODE-2022-35256

The llhttp parser in the http module in Node v18.7.0 does not correctly handle header fields that are not terminated with CLRF. This may result in HTTP Request Smuggling...

BIT-GOLANG-2022-2880 Incorrect sanitization of forwarded query parameters in net/http/httputil

Requests forwarded by ReverseProxy include the raw query parameters from the inbound request, including unparsable parameters rejected by net/http. This could permit query parameter smuggling when a Go proxy forwards a parameter with an unparsable value. After fix, ReverseProxy sanitizes the quer...

BIT-NODE-2023-30589

The llhttp parser in the http module in Node v20.2.0 does not strictly use the CRLF sequence to delimit HTTP requests. This can lead to HTTP Request Smuggling HRS. The CR character without LF is sufficient to delimit HTTP header fields in the llhttp parser. According to RFC7230 section 3, only th...

BIT-HAPROXY-2021-40346

An integer overflow exists in HAProxy 2.0 through 2.5 in htxaddheader that can be exploited to perform an HTTP request smuggling attack, allowing an attacker to bypass all configured http-request HAProxy ACLs and possibly other ACLs...

BIT-APACHE-2022-22720 HTTP request smuggling vulnerability in Apache HTTP Server 2.4.52 and earlier

Apache HTTP Server 2.4.52 and earlier fails to close inbound connection when errors are encountered discarding the request body, exposing the server to HTTP Request Smuggling...

BIT-HAPROXY-2023-25725

HAProxy before 2.7.3 may allow a bypass of access control because HTTP/1 headers are inadvertently lost in some situations, aka "request smuggling." The HTTP header parsers in HAProxy may accept empty header field names, which could be used to truncate the list of HTTP headers and thus make some...

BIT-HAPROXY-2023-25950

HTTP request/response smuggling vulnerability in HAProxy version 2.7.0, and 2.6.1 to 2.6.7 allows a remote attacker to alter a legitimate user's request. As a result, the attacker may obtain sensitive information or cause a denial-of-service DoS condition...

BIT-APACHE-2022-26377 mod_proxy_ajp: Possible request smuggling

Inconsistent Interpretation of HTTP Requests 'HTTP Request Smuggling' vulnerability in modproxyajp of Apache HTTP Server allows an attacker to smuggle requests to the AJP server it forwards requests to. This issue affects Apache HTTP Server Apache HTTP Server 2.4 version 2.4.53 and prior versions...
