A possible denial of service vulnerability exists in Rack <2.0.9.1, <2.1.4.1 and <2.2.3.1 in the multipart parsing component of Rack.

The remote Redhat Enterprise Linux 7 / 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2022:7242 advisory.

  - rubygem-rack: crafted multipart POST request may cause a DoS (CVE-2022-30122)

  - A possible denial of service vulnerability exists in Rack <2.0.9.1, <2.1.4.1 and <2.2.3.1 in the multipart     parsing component of Rack. (CVE-2022-30122)

  - 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. (CVE-2022-30123)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote Debian 11 host has a package installed that is affected by multiple vulnerabilities as referenced in the dsa-5530 advisory.

  - A possible denial of service vulnerability exists in Rack <2.0.9.1, <2.1.4.1 and <2.2.3.1 in the multipart     parsing component of Rack. (CVE-2022-30122)

  - 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. (CVE-2022-30123)

  - 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. (CVE-2022-44570)

  - There is a denial of service vulnerability in the Content-Disposition parsingcomponent of Rack fixed in     2.0.9.2, 2.1.4.2, 2.2.4.1, 3.0.0.1. 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. (CVE-2022-44571)

  - A denial of service vulnerability in the multipart parsing component of Rack fixed in 2.0.9.2, 2.1.4.2,     2.2.4.1 and 3.0.0.1 could allow an attacker tocraft input that can cause RFC2183 multipart boundary     parsing in Rack to take an unexpected amount of time, possibly resulting in a denial of service attack     vector. Any applications that parse multipart posts using Rack (virtually all Rails applications) are     impacted. (CVE-2022-44572)

  - A DoS vulnerability exists in Rack <v3.0.4.2, <v2.2.6.3, <v2.1.4.3 and <v2.0.9.3 within in the Multipart     MIME parsing code in which could allow an attacker to craft requests that can be abuse to cause multipart     parsing to take longer than expected. (CVE-2023-27530)

  - The Ruby on Rails advisory describes this vulnerability as follows: (CVE-2023-27539)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote Ubuntu 16.04 ESM / 18.04 ESM / 20.04 ESM host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5253-1 advisory.

  - 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. (CVE-2019-16782)

  - A reliance on cookies without validation/integrity check security vulnerability exists in rack < 2.2.3,     rack < 2.1.4 that makes it is possible for an attacker to forge a secure or host-only cookie prefix.
    (CVE-2020-8184)
