Ruby/rack/2.2.6.3
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.

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

- https://lists.debian.org/debian-lts-announce/2024/04/msg00022.html
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.

Possible Denial of Service Vulnerability in Rack Header Parsing
There is a possible denial of service vulnerability in the header parsing routines in Rack. This vulnerability has been assigned the CVE identifier CVE-2024-26146.
Versions Affected: All. Not affected: None Fixed Versions: 2.0.9.4, 2.1.4.4, 2.2.8.1, 3.0.9.1
Impact
Carefully crafted headers can cause header parsing in Rack to take longer than expected resulting in a possible denial of service issue. Accept and Forwarded headers are impacted.
Ruby 3.2 has mitigations for this problem, so Rack applications using Ruby 3.2 or newer are unaffected.
Releases
The fixed releases are available at the normal locations.
Workarounds
There are no feasible workarounds for this issue.

- https://github.com/advisories/GHSA-c6qg-cjj8-47qp
- https://github.com/rack/rack/commit/231ef369ad0b542575fb36c74fcfcfabcf6c530c
- https://github.com/rack/rack/commit/ee7919ea04303717858be1c3f16b406adc6d8cff
There is a denial of service vulnerability in the header parsing component of Rack. This vulnerability has been assigned the CVE identifier CVE-2023-27539.
Versions Affected: >= 2.0.0 Not affected: None. Fixed Versions: 2.2.6.4, 3.0.6.1
Impact
Carefully crafted input can cause header parsing in Rack to take an unexpected amount of time, possibly resulting in a denial of service attack vector. Any applications that parse headers using Rack (virtually all Rails applications) are impacted.
Workarounds
Setting Regexp.timeout in Ruby 3.2 is a possible workaround.
Rack has possible DoS Vulnerability with Range Header

- https://github.com/advisories/GHSA-xj5v-6v4g-jfw6
- https://nvd.nist.gov/vuln/detail/CVE-2024-26141
Possible DoS Vulnerability with Range Header in Rack
There is a possible DoS vulnerability relating to the Range request header in Rack. This vulnerability has been assigned the CVE identifier CVE-2024-26141.
Versions Affected: >= 1.3.0. Not affected: < 1.3.0 Fixed Versions: 3.0.9.1, 2.2.8.1
Impact
Carefully crafted Range headers can cause a server to respond with an unexpectedly large response. Responding with such large responses could lead to a denial of service issue.
Vulnerable applications will use the Rack::File
middleware or the
Rack::Utils.byte_ranges
methods (this includes Rails applications).
Releases
The fixed releases are available at the normal locations.
Workarounds
There are no feasible workarounds for this issue.

Possible Denial of Service Vulnerability in Rack’s header parsing
There is a denial of service vulnerability in the header parsing component of Rack. This vulnerability has been assigned the CVE identifier CVE-2023-27539.
Versions Affected: >= 2.0.0 Not affected: None. Fixed Versions: 2.2.6.4, 3.0.6.1
Impact

Denial of Service Vulnerability in Rack Content-Type Parsing
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.
Releases
The fixed releases are available at the normal locations.
Workarounds
There are no feasible workarounds for this issue.
