Astra Linux – Vulnerability in Apache2

The out-of-bounds write vulnerability in the modsed module of the Apache HTTP Server allows an attacker to overwrite heap memory with data provided by the attacker. This issue affects Apache HTTP Server version 2.4.2.52 and earlier versions...

Astra Linux – Vulnerability in JRuby

Before Ruby 2.2.10, 2.3.x before 2.3.7, 2.4.x before 2.4.4, 2.5.x before 2.5.1, and 2.6.0-preview1, an HTTP Response Splitting attack was possible. An attacker could inject a crafted key and value into an HTTP response for the WEBrick HTTP server...

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 golang-golang-x-net, golang-1.19

A maliciously crafted HTTP/2 stream could cause excessive CPU consumption in the HPACK decoder, enough to trigger a denial of service due to a small number of small requests...

Astra Linux – Vulnerability in Jetty9

Eclipse Jetty provides a web server and servlet container. In versions 11.0.0 through 11.0.15, 10.0.0 through 10.0.15, and 9.0.0 through 9.4.52, an integer overflow in MetaDataBuilder.checkSize allows HTTP/2 HPACK header values to exceed their size limit. MetaDataBuilder.java determines whether a...

Astra Linux – Vulnerability in Netty

Netty 4.1.43.Final allows HTTP Request Smuggling because it mishandles Transfer-Encoding whitespace such as a spaceTransfer-Encoding:chunked line and a later Content-Length header. This issue exists due to an incomplete fix for CVE-2019-16869...

Astra Linux – Vulnerability in Apache2

HTTP/2 incoming headers that exceed the limit are temporarily buffered in nghttp2 in order to generate an informative HTTP 413 response. If a client continues to send headers, this can lead to memory exhaustion...

Astra Linux – Vulnerability in curl

A vulnerability related to insufficiently protected credentials, addressed in curl 7.83.0, may cause authentication or cookie header data to be leaked during HTTP redirections to the same host, but using a different port number...

Astra Linux – Vulnerability in curl

There is an information disclosure vulnerability in curl v8.1.0 when performing HTTPS transfers. libcurl may incorrectly use the read callback CURLOPTREADFUNCTION to request data to be sent, even when the CURLOPTPOSTFIELDS option is set. This occurs if the same handle was previously used to issue...

Astra Linux – Vulnerability in golang-golang-x-net

An attacker can cause excessive memory usage in a Go server that accepts HTTP/2 requests. HTTP/2 server connections include a cache of HTTP header keys sent by the client. Although the total number of entries in this cache is limited, an attacker who sends very large keys can cause the server to...

Astra Linux – Vulnerability in Perl

HTTP::Tiny, a Perl core module since version 5.13.9 and available as a standalone package on CPAN, has an insecure default TLS configuration. In this configuration, users are required to explicitly choose to verify certificates...

Astra Linux - Vulnerability in Golang-1.19

The net/http HTTP/1.1 client mishandled the situation where a server responds to a request with an “Expect: 100-continue” header with a non-informational 200 or higher status. This mishandling could leave a client connection in an invalid state, causing the next request sent on that connection to...

Astra Linux – Vulnerability in Tomcat9

There is a vulnerability in Apache Tomcat when using the APR/Native connector, involving concurrent execution with shared resources and improper synchronization known as “race condition”. This issue is particularly noticeable during client-initiated closures of HTTP/2 connections. This issue...

Astra Linux – Vulnerabilities in nghttp2, jetty9, netty, tomcat9

The HTTP/2 protocol allows for a denial of service server resource consumption, as request cancellation can quickly reset many streams, as exploited in practice from August to October 2023...

Astra Linux – Vulnerability in Python 2.7, Pypy

In Python 3.x versions prior to 3.5.10, 3.6.x versions prior to 3.6.12, 3.7.x versions prior to 3.7.9, and 3.8.x versions prior to 3.8.5, CRLF injection is allowed if the attacker controls the HTTP request method, as demonstrated by inserting CR and LF control characters in the first argument of...

Astra Linux – Vulnerability in the supervisor

In Supervisor version 4.0.2, an unauthenticated user can read log files or restart a service. Note: The maintainer confirmed that the affected component, inethttpserver, is not enabled by default. However, if the user enables it and does not set a password, Supervisor will log a warning message...

Astra Linux – Vulnerability in Jetty9

Jetty is a Java-based web server and servlet engine. An HTTP/2 SSL connection that is established and becomes TCP congested may be leaked when it times out. An attacker can cause many connections to end up in this state, and the server may run out of file descriptors, eventually causing the serve...

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 a vulnerability related to improper input validation in Apache Tomcat. Tomcat did not restrict HTTP/0.9 requests to only the GET method. If a security constraint was configured to allow HEAD requests to a URI but deny GET requests, users could bypass this constraint on GET requests by...

Astra Linux – Vulnerability in Twisted

In Twisted Web version 19.10.0, there was an HTTP request splitting vulnerability. When two content-length headers were provided, the system ignored the first header. When the second content-length value was set to zero, the request body was interpreted as a pipelined request...
