UBUNTU-CVE-2022-41556

A resource leak in gwbackend.c in lighttpd 1.4.56 through 1.4.66 could lead to a denial of service connection-slot exhaustion after a large amount of anomalous TCP behavior by clients. It is related to RDHUP mishandling in certain HTTP/1.1 chunked situations. Use of modfastcgi is, for example,...

golang: net/http: improper sanitization of Transfer-Encoding header

A flaw was found in golang. The HTTP/1 client accepted invalid Transfer-Encoding headers indicating "chunked" encoding. This issue could allow request smuggling, but only if combined with an intermediate server that also improperly accepts the header as invalid...

llhttp: HTTP Request Smuggling when parsing the body of chunked requests

An HTTP Request Smuggling HRS vulnerability was found in the llhttp library, used by Node.JS. During the parsing of chunked messages, the chunk size parameter was not validated properly. In situations where HTTP conversations are being proxied such as proxy, reverse-proxy, load-balancer, an...

tomcat: HTTP request smuggling when used with a reverse proxy

Apache Tomcat 10.0.0-M1 to 10.0.6, 9.0.0.M1 to 9.0.46 and 8.5.0 to 8.5.66 did not correctly parse the HTTP transfer-encoding request header in some circumstances leading to the possibility to request smuggling when used with a reverse proxy. Specifically: - Tomcat incorrectly ignored the transfer...

GHSA-WQ2P-Q66W-Q8GP Apache Tomcat Denial of Service vulnerability

Apache Tomcat before 6.0.39, 7.x before 7.0.50, and 8.x before 8.0.0-RC10 processes chunked transfer coding without properly handling 1 a large total amount of chunked data or 2 whitespace characters in an HTTP header value within a trailer field, which allows remote attackers to cause a denial o...

Integer Overflow or Wraparound in Apache Tomcat

Integer overflow in the parseChunkHeader function in java/org/apache/coyote/http11/filters/ChunkedInputFilter.java in Apache Tomcat before 6.0.40, 7.x before 7.0.53, and 8.x before 8.0.4 allows remote attackers to cause a denial of service resource consumption via a malformed chunk size in chunke...

GHSA-42J3-498Q-M6VP Improper Input Validation in Apache Tomcat

java/org/apache/coyote/http11/filters/ChunkedInputFilter.java in Apache Tomcat 6.x before 6.0.42, 7.x before 7.0.55, and 8.x before 8.0.9 does not properly handle attempts to continue reading data after an error has occurred, which allows remote attackers to conduct HTTP request smuggling attacks...

Inconsistent Interpretation of HTTP Requests in twisted.web

The Twisted Web HTTP 1.1 server, located in the twisted.web.http module, parsed several HTTP request constructs more leniently than permitted by RFC 7230: 1. The Content-Length header value could have a + or - prefix. 2. Illegal characters were permitted in chunked extensions, such as the LF \n...

Puma vulnerable to HTTP Request Smuggling

When using Puma behind a proxy that does not properly validate that the incoming HTTP request matches the RFC7230 standard, Puma and the frontend proxy may disagree on where a request starts and ends. This would allow requests to be smuggled via the front-end proxy to Puma. The following...
