Summary IBM WebSphere Application Server and WebSphere Application Server Liberty are affected by a denial of service, HTTP Response and Request Smuggling vulnerabilities when servlet-3.0, servlet-3.1, servlet-4.0, servlet-5.0, servlet-6.0, or servlet-6.1 is enabled. Vulnerability Details...

aiohttp: AIOHTTP: HTTP Request Smuggling via WebSocket Upgrade

A flaw was found in AIOHTTP, an asynchronous HTTP client/server framework. This vulnerability allows a remote attacker to perform HTTP request smuggling due to an edge case in the WebSocket upgrade procedure. When a WebSocket upgrade request includes a body, the parser may switch protocols before...

Astra Linux – Vulnerability in Puma

Puma is a web server for Ruby/Rack applications built for parallelism. Prior to version 6.4.2, Puma exhibited incorrect behavior when parsing chunked transfer encoding bodies, allowing HTTP request smuggling. The fixed versions limit the size of chunk extensions. Without this limitation, an...

Astra Linux – Vulnerability in Netty

Netty is an open-source, asynchronous event-driven network application framework for rapid development of maintainable high-performance protocol servers and clients. In Netty io.netty:netty-codec-http2, before version 4.1.60.Final, there was a vulnerability that allowed for request smuggling. If...

Astra Linux – Vulnerability in Tomcat9

There is an input validation vulnerability in Apache Tomcat. Versions of Tomcat from 11.0.0-M1 through 11.0.0-M11, from 10.1.0-M1 through 10.1.13, from 9.0.0-M1 through 9.0.81, and from 8.5.0 through 8.5.93 did not properly parse HTTP trailer headers. A specially crafted, invalid trailer header...

Astra Linux – Vulnerability in Squid

SQUID is vulnerable to HTTP request smuggling, which is caused by the laxity of the chunked decoder. This allows a remote attacker to perform Request/Response smuggling beyond the firewall and frontend security systems...

Astra Linux – Vulnerability in Netty

Netty is an asynchronous, event-driven network application framework for developing maintainable, high-performance protocol servers and clients. In versions 4.1.124.Final and 4.2.0.Alpha3 through 4.2.4.Final, Netty incorrectly accepts standalone newline characters LF as a chunk-size line...

Astra Linux – Vulnerability in JRuby

A vulnerability was discovered in Ruby versions 2.5.8, 2.6.x up to 2.6.6, and 2.7.x up to 2.7.1. WEBrick, a simple HTTP server bundled with Ruby, did not rigorously check the transfer-encoding header value. An attacker could potentially exploit this vulnerability to bypass a reverse proxy which...

Astra Linux – Vulnerability in Waitress

Waitress version 1.3.1 allows for the smuggling of requests by sending the Content-Length header twice. Waitress would fold the two Content-Length headers together, and since it cannot convert the now comma-separated values into integers, it internally sets the Content-Length to 0. If two...

Astra Linux – Vulnerability in Netty

Netty is an asynchronous, event-driven network application framework. In versions prior to 4.1.129.Final and 4.2.8.Final, the io.netty.handler.codec.http.HttpRequestEncoder had a CRLF injection in the request URI during request construction. This led to request smuggling when HttpRequestEncoder w...

Astra Linux – Vulnerability in Apache2

Inconsistent interpretation of HTTP requests: The “HTTP Request Smuggling” vulnerability in modproxyajp of the Apache HTTP Server allows an attacker to secretly send requests to the AJP server to which the server forwards requests. This issue affects the Apache HTTP Server version 2.4.53 and...

Astra Linux – Vulnerability in Tomcat9

Apache Tomcat versions 10.0.0-M1 to 10.0.6, 9.0.0.M1 to 9.0.46, and 8.5.0 to 8.5.66 failed to properly parse the HTTP transfer-encoding request header under certain circumstances, which could lead to requests for data smuggling when used with a reverse proxy. Specifically: - Tomcat incorrectly...

Astra Linux – Vulnerability in Jetty9

Jetty is a Java-based web server and servlet engine. Prior to versions 9.4.52, 10.0.16, 11.0.16, and 12.0.1, Jetty accepted the + character that followed the content-length value in an HTTP/1 header field. This was more permissive than what is allowed by the RFC, and other servers routinely...

Astra Linux – Vulnerability in Waitress

Waitress, in version 1.3.1, implemented a “MAY” clause from RFC7230. This clause states: “Although the line terminator for the start-line and header fields is the sequence CRLF, a recipient MAY recognize a single LF as a line terminator and ignore any preceding CR.” Unfortunately, if a front-end...

Astra Linux – Vulnerability in Puma

Puma is a Ruby/Rack web server designed for parallelism. Prior to versions 6.3.1 and 5.6.7, Puma exhibited incorrect behavior when parsing chunked transfer encoding bodies and zero-length Content-Length headers, which could allow HTTP request smuggling. The severity of this issue depends heavily ...
