Ruby/rack/2.2.6.2

Rack provides a minimal, modular and adaptable interface for developing web applications in Ruby. By wrapping HTTP requests and responses in the simplest way possible, it unifies and distills the API for web servers, web frameworks, and software in between (the so-called middleware) into a single method call.

10 Security Vulnerabilities

Rack vulnerable to ReDoS in content type parsing (2nd degree polynomial)

Published date: 2024-02-28T22:57:26Z
CVE: CVE-2024-25126
Links:

Summary

module Rack
  class MediaType
    SPLIT_PATTERN = %r{\s*[;,]\s*}

The above regexp is subject to ReDos. 50K blank characters as a prefix to the header will take over 10s to split.

PoC

A simple HTTP request with lots of blank characters in the content-type header:

request["Content-Type"] = (" " * 50_000) + "a,"

Impact

It's a very easy to craft ReDoS. Like all ReDoS the impact is debatable.

Affected versions: ["2.2.3", "2.2.2", "2.2.1", "2.2.0", "2.1.4", "2.1.3", "2.1.2", "2.1.1", "2.1.0", "2.0.9", "2.0.8", "2.0.7", "2.0.6", "2.0.5", "2.0.4", "2.0.3", "2.0.2", "2.0.1", "2.0.0.rc1", "2.0.0.alpha", "1.6.13", "1.6.12", "1.6.11", "1.6.10", "1.6.9", "1.6.8", "1.6.7", "1.6.6", "1.6.5", "1.6.4", "1.6.3", "1.6.2", "1.6.1", "1.6.0", "1.6.0.beta2", "1.6.0.beta", "1.5.5", "1.5.4", "1.5.3", "1.5.2", "1.5.1", "1.5.0", "1.5.0.beta.2", "1.5.0.beta.1", "1.4.7", "1.4.6", "1.4.5", "1.4.4", "1.4.3", "1.4.2", "1.4.1", "1.4.0", "1.3.10", "1.3.9", "1.3.8", "1.3.7", "1.3.6", "1.3.5", "1.3.4", "1.3.3", "1.3.2", "1.3.1", "1.3.0", "1.3.0.beta2", "1.3.0.beta", "1.2.8", "1.2.7", "1.2.6", "1.2.5", "1.2.4", "1.2.3", "1.2.2", "1.2.1", "1.2.0", "1.1.6", "1.1.5", "1.1.4", "1.1.3", "1.1.2", "1.1.1", "1.1.1.pre", "1.1.0", "1.0.1", "1.0.0", "0.9.1", "0.9.0", "0.4.0", "2.2.3.1", "2.1.4.1", "2.0.9.1", "2.2.4", "2.2.5", "2.2.6", "2.2.6.2", "2.2.6.1", "2.1.4.2", "2.0.9.2", "2.2.6.3", "2.1.4.3", "2.0.9.3", "2.2.6.4", "2.2.7", "2.2.8", "2.1.4.4", "2.0.9.4", "3.0.0", "3.0.1", "3.0.2", "3.0.3", "3.0.4", "3.0.4.1", "3.0.4.2", "3.0.5", "3.0.6", "3.0.6.1", "3.0.7", "3.0.8", "3.0.9"]

Denial of Service Vulnerability in Rack Content-Type Parsing

Published date: 2024-02-21
CVE: 2024-25126
Links:

There is a possible denial of service vulnerability in the content type parsing component of Rack. This vulnerability has been assigned the CVE identifier CVE-2024-25126.

Versions Affected: >= 0.4 Not affected: < 0.4 Fixed Versions: 3.0.9.1, 2.2.8.1

Impact

Carefully crafted content type headers can cause Rack’s media type parser to take much longer than expected, leading to a possible denial of service vulnerability.

Impacted code will use Rack’s media type parser to parse content type headers. This code will look like below:

request.media_type

## OR
request.media_type_params

## OR
Rack::MediaType.type(content_type)

Some frameworks (including Rails) call this code internally, so upgrading is recommended!

All users running an affected release should either upgrade or use one of the workarounds immediately.
