rack Vulnerability Remediation Guidance
| CVE | Description | Full list of Impacted Versions | Fix |
|---|---|---|---|
| CVE-2024-39316 | Rack is a modular Ruby web server interface. Starting in version 3.1.0 and prior to version 3.1.5, Regular Expression Denial of Service (ReDoS) vulnerability exists in the `Rack::Request::Helpers` module when parsing HTTP Accept headers. This vulnerability can be exploited by an attacker sending specially crafted `Accept-Encoding` or `Accept-Language` headers, causing the server to spend excessive time processing the request and leading to a Denial of Service (DoS). The fix for CVE-2024-26146 was not applied to the main branch and thus while the issue was fixed for the Rack v3.0 release series, it was not fixed in the v3.1 release series until v3.1.5. Users of versions on the 3.1 branch should upgrade to version 3.1.5 to receive the fix. | 3.1.4, 3.1.3, 3.1.2, 3.1.1, 3.1.0 | Patch → 3.1.5 |
| CVE-2024-26146 | Rack is a modular Ruby web server interface. 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. This vulnerability is fixed in 2.0.9.4, 2.1.4.4, 2.2.8.1, and 3.0.9.1. | 1.2.1, 1.5.2, 1.0.1, 1.2.2, 1.3.2, 1.3.4, 1.5.0, 1.6.1 (Show all) | Patch → 2.2.8.1 |
| CVE-2024-26141 | Rack is a modular Ruby web server interface. 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). The vulnerability is fixed in 3.0.9.1 and 2.2.8.1. | 1.5.2, 1.3.2, 1.3.4, 1.5.0, 1.6.1, 1.6.0, 1.3.5, 1.3.6 (Show all) | Patch → 2.2.8.1 |
| CVE-2024-25126 | Rack is a modular Ruby web server interface. 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 (ReDos 2nd degree polynomial). This vulnerability is patched in 3.0.9.1 and 2.2.8.1. | 1.2.1, 1.5.2, 1.0.1, 1.2.2, 1.3.2, 1.3.4, 1.5.0, 1.6.1 (Show all) | Patch → 2.2.8.1 |

This could allow an attacker to craft an input that can cause Content-Disposition header parsing in Rackto take an unexpected amount of time, possibly resulting in a denial ofservice attack vector. This header is used typically used in multipartparsing. Any applications that parse multipart posts using Rack (virtuallyall Rails applications) are impacted. | 2.0.4, 2.0.5, 3.0.3, 3.0.0, 2.2.3, 3.0.4, 3.0.2, 2.2.4 (Show all) | Patch → 2.2.8.1 |
| CVE-2022-44570 | A denial of service vulnerability in the Range header parsing component of Rack >= 1.5.0. A Carefully crafted input can cause the Range header parsing component in Rack to take an unexpected amount of time, possibly resulting in a denial of service attack vector. Any applications that deal with Range requests (such as streaming applications, or applications that serve files) may be impacted. | 1.5.2, 1.5.0, 1.6.1, 1.6.0, 2.0.4, 1.5.1, 2.0.5, 1.5.3 (Show all) | Patch → 2.2.8.1 |
| CVE-2022-30123 | A sequence injection vulnerability exists in Rack <2.0.9.1, <2.1.4.1 and <2.2.3.1 which could allow is a possible shell escape in the Lint and CommonLogger components of Rack. | 1.2.1, 1.5.2, 1.0.1, 1.2.2, 1.3.2, 1.3.4, 1.5.0, 1.6.1 (Show all) | Patch → 2.2.8.1 |

| CVE-2019-16782 | There's a possible information leak / session hijack vulnerability in Rack (RubyGem rack). This vulnerability is patched in versions 1.6.12 and 2.0.8. Attackers may be able to find and hijack sessions by using timing attacks targeting the session id. Session ids are usually stored and indexed in a database that uses some kind of scheme for speeding up lookups of that session id. By carefully measuring the amount of time it takes to look up a session, an attacker may be able to find a valid session id and hijack the session. The session id itself may be generated randomly, but the way the session is indexed by the backing store does not use a secure comparison. | 1.2.1, 1.5.2, 1.0.1, 1.2.2, 1.3.2, 1.3.4, 1.5.0, 1.6.1 (Show all) | Patch → 2.2.8.1 |
| CVE-2018-16471 | There is a possible XSS vulnerability in Rack before 2.0.6 and 1.6.11. Carefully crafted requests can impact the data returned by the `scheme` method on `Rack::Request`. Applications that expect the scheme to be limited to 'http' or 'https' and do not escape the return value could be vulnerable to an XSS attack. Note that applications using the normal escaping mechanisms provided by Rails may not impacted, but applications that bypass the escaping mechanisms, or do not use them may be vulnerable. | 1.2.1, 1.5.2, 1.0.1, 1.2.2, 1.3.2, 1.3.4, 1.5.0, 1.6.1 (Show all) | Patch → 2.2.8.1 |
| CVE-2018-16470 | There is a possible DoS vulnerability in the multipart parser in Rack before 2.0.6. Specially crafted requests can cause the multipart parser to enter a pathological state, causing the parser to use CPU resources disproportionate to the request size. | 2.0.4, 2.0.5 | Patch → 2.2.8.1 |
| CVE-2015-3225 | lib/rack/utils.rb in Rack before 1.5.4 and 1.6.x before 1.6.2, as used with Ruby on Rails 3.x and 4.x and other products, allows remote attackers to cause a denial of service (SystemStackError) via a request with a large parameter depth. | 1.5.2, 1.5.0, 1.6.1, 1.6.0, 1.4.5, 1.4.2, 1.4.1, 1.4.4 (Show all) | Patch → 2.2.8.1 |
