A flaw was found in the Pacemaker configuration tool (pcs). The pcs daemon was allowing expired accounts, and accounts with expired passwords to login when using PAM authentication. Therefore, unprivileged expired accounts that have been denied access could still login.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - A flaw was found in the Pacemaker configuration tool (pcs). The pcs daemon was allowing expired accounts,     and accounts with expired passwords to login when using PAM authentication. Therefore, unprivileged     expired accounts that have been denied access could still login. (CVE-2022-1049)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Ubuntu 16.04 LTS / 20.04 LTS / 22.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7614-1 advisory.

    Cedric Buissart discovered that pcs did not correctly handle certain parameters. An attacker could     possibly use this issue to leak sensitive information or elevate their privileges. This issue only     affected Ubuntu 16.04 LTS. (CVE-2018-1086)

    Ondrej Mular discovered that pcs did not correctly handle Unix socket permissions. An attacker could     possibly use this issue to elevate their privileges. This issue only affected Ubuntu 22.04 LTS.
    (CVE-2022-2735)

    It was discovered that pcs did not correctly handle PAM authentication. An attacker could possibly use     this issue to bypass authentication mechanisms. This issue only affected Ubuntu 20.04 LTS and

    Ubuntu 22.04 LTS. (CVE-2022-1049)

    It was discovered that pcs did not correctly handle the validation of Node names. An attacker could     possibly use this issue to execute a cross-site scripting (XSS) attack. This issue only affected Ubuntu     16.04 LTS. (CVE-2017-2661)

The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALINUX3-SA-2024:0132 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2022-1049:
    A flaw was found in the Pacemaker configuration tool (pcs). The pcs daemon was allowing expired accounts,     and accounts with expired passwords to login when using PAM authentication. Therefore, unprivileged     expired accounts that have been denied access could still login.

    CVE-2022-2735:
    A vulnerability was found in the PCS project. This issue occurs due to incorrect permissions on a Unix     socket used for internal communication between PCS daemons. A privilege escalation could happen by     obtaining an authentication token for a hacluster user. With the hacluster token, this flaw allows an     attacker to have complete control over the cluster managed by PCS.

    CVE-2023-27530:
    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-2023-27539:
    A denial of service vulnerability was found in rubygem-rack in how it parses headers. A carefully crafted     input can cause header parsing to take an unexpected amount of time, possibly resulting in a denial of     service.

    CVE-2024-25126:
    Rack is a modular Ruby web server interface. Carefully crafted content type headers can cause Racks     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.

    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.

    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.
