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 Ubuntu 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-7036-1 advisory.

    It was discovered that Rack was not properly parsing data when processing multipart POST requests. If a     user or automated system were tricked into sending a specially crafted multipart POST request to an     application using Rack, a remote attacker could possibly use this issue to cause a denial of service.
    (CVE-2022-30122)

    It was discovered that Rack was not properly escaping untrusted data when performing logging operations,     which could cause shell escaped sequences to be written to a terminal. If a user or automated system were     tricked into sending a specially crafted request to an application using Rack, a remote attacker could     possibly use this issue to execute arbitrary code in the machine running the application. (CVE-2022-30123)

    It was discovered that Rack did not properly structure regular expressions in some of its parsing     components, which could result in uncontrolled resource consumption if an application using Rack received     specially crafted input. A remote attacker could possibly use this issue to cause a denial of service.
    (CVE-2022-44570, CVE-2022-44571)

    It was discovered that Rack did not properly structure regular expressions in its multipart parsing     component, which could result in uncontrolled resource consumption if an application using Rack to parse     multipart posts received specially crafted input. A remote attacker could possibly use this issue to cause     a denial of service. (CVE-2022-44572)

  - 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 version of pcs installed on the remote host is prior to 0.9.169-3. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2022-1895 advisory.

    A denial of service flaw was found in ruby-rack. An attacker crafting multipart POST requests can cause     Rack's multipart parser to take much longer than expected, leading to a denial of service.
    (CVE-2022-30122)

    A flaw was found in ruby gem-rack. This flaw allows a malicious actor to craft requests that can cause     shell escape sequences to be written to the terminal via rack's `Lint` middleware and `CommonLogger`     middleware. This issue can leverage these escape sequences to execute commands in the victim's terminal.
