An issue was discovered in Cobbler before 3.3.1. Files in /etc/cobbler are world readable. Two of those files contain some sensitive information that can be exposed to a local user who has non-privileged access to the server. The users.digest file contains the sha2-512 digest of users in a Cobbler local installation. In the case of an easy-to-guess password, it's trivial to obtain the plaintext string. The settings.yaml file contains secrets such as the hashed default password.

The remote Ubuntu 16.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6475-1 advisory.

    It was discovered that Cobbler did not properly handle user input, which could result in an absolute path     traversal. An attacker could possibly

    use this issue to read arbitrary files. (CVE-2014-3225)

    It was discovered that Cobbler did not properly handle user input, which could result in command     injection. An attacker could possibly use this

    issue to execute arbitrary code with high privileges.

    (CVE-2017-1000469, CVE-2021-45082)

    It was discovered that Cobbler did not properly hide private functions in a class. A remote attacker could     possibly use this issue to gain high

    privileges and upload files to an arbitrary location.

    (CVE-2018-10931, CVE-2018-1000225, CVE-2018-1000226)

    Nicolas Chatelain discovered that Cobbler did not properly handle user

    input, which could result in log poisoning. A remote attacker could

    possibly use this issue to bypass authorization, write in an arbitrary

    file, or execute arbitrary code.

    (CVE-2021-40323, CVE-2021-40324, CVE-2021-40325)

    It was discovered that Cobbler did not properly handle file permissions

    during package install or update operations. An attacker could possibly

    use this issue to perform a privilege escalation attack. (CVE-2021-45083)

    It was discovered that Cobbler did not properly process credentials for

    expired accounts. An attacker could possibly use this issue to login to

    the platform with an expired account or password. (CVE-2022-0860)
