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 golang-golang-x-net

A request smuggling attack is possible when using MaxBytesHandler. When using MaxBytesHandler, the body of an HTTP request is not fully consumed. When the server attempts to read HTTP2 frames from the connection, it will instead be reading the body of the HTTP request, which can be manipulated by...

Astra Linux – Vulnerability in Puma

Puma is a simple, fast, multi-threaded, parallel HTTP 1.1 server for Ruby/Rack applications. When using Puma behind a proxy that does not properly validate that the incoming HTTP requests comply with the RFC7230 standard, Puma and the frontend proxy may disagree about where the requests start and...

Astra Linux – Vulnerability in Apache2

Some modproxy configurations on the Apache HTTP Server versions 2.4.0 through 2.4.55 allow for an HTTP Request Smuggling attack. These configurations are affected when modproxy is enabled along with some form of RewriteRule or ProxyPassMatch, where a non-specific pattern matches a portion of the...

Astra Linux – Vulnerability in Gunicorn

Gunicorn fails to properly validate Transfer-Encoding headers, resulting in HTTP Request Smuggling HRS vulnerabilities. By creating requests with conflicting Transfer-Encoding headers, attackers can bypass security restrictions and access restricted endpoints. This issue arises due to Gunicorn’s...

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 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 Twisted

Twisted is an event-based framework for internet applications, compatible with Python 3.6+. Before version 22.4.0rc1, the Twisted Web HTTP 1.1 server, located in the twisted.web.http module, parsed several HTTP request constructs more leniently than allowed by RFC 7230. This non-conformant parsin...

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, which allowed HTTP request smuggling. The fixed versions limit the size of chunk extensions. Without this limitation, an...

Astra Linux – Vulnerability in Puma

Puma is an HTTP 1.1 server for Ruby/Rack applications. Prior to versions 5.5.1 and 4.3.9, using “puma” with a proxy that forwards HTTP header values containing the LF character could lead to HTTP request smuggling. A client could secretly send a request through a proxy, causing the proxy to send ...

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 2.4.54 and...

Astra Linux – Vulnerability in Apache2

Apache HTTP Server 2.4.52 and earlier fail to close inbound connections when errors occur during the discarding of the request body, exposing the server to HTTP Request Smuggling attacks...

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 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 Waitress

Waitress is a Web Server Gateway Interface server for Python 2 and 3. When using Waitress versions 2.1.0 and earlier behind a proxy that does not properly validate whether the incoming HTTP requests comply with the RFC7230 standard, Waitress and the frontend proxy may disagree on where one reques...

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 terminato...

Astra Linux - уязвимость в tomcat9

Inconsistent interpretation of HTTP requests „HTTP Request/Response Smuggling“ vulnerability in Apache Tomcat due to an invalid chunk extension. This issue affects Apache Tomcat: versions from 11.0.0-M1 through 11.0.18, from 10.1.0-M1 through 10.1.52, from 9.0.0.M1 through 9.0.115, from 8.5.0...

Astra Linux – Vulnerability in http-parser

HTTP request smuggling in Node.js versions 10, 12, and 13 causes the delivery of malicious payloads when transfer-encoding is malformed...

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 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 did not correctly parse the HTTP transfer-encoding request header in some circumstances, which could lead to requests for data smuggling when used with a reverse proxy. Specifically: - Tomcat incorrectly ignored t...
