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.
    (CVE-2022-30123)

The remote Ubuntu 18.04 ESM / 20.04 ESM / 22.04 ESM host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5896-1 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.

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.

    It was discovered that Rack insecurely handled session ids. An unauthenticated remote attacker could     possibly use this issue to perform a timing attack and hijack sessions. (CVE-2019-16782)

    It was discovered that Rack was incorrectly handling cookies during parsing, not validating them or     performing the necessary integrity checks. An attacker could possibly use this issue to overwrite existing     cookie data and gain control over a remote system's behaviour. This issue only affected Ubuntu 14.04 ESM.
    (CVE-2020-8184)

    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. This     issue was only fixed in Ubuntu 14.04 ESM and Ubuntu 16.04 ESM. (CVE-2022-30122)
