Cobbler version Verified as present in Cobbler versions 2.6.11+, but code inspection suggests at least 2.0.0+ or possibly even older versions may be vulnerable contains a Incorrect Access Control vulnerability in XMLRPC API (/cobbler_api) that can result in Privilege escalation, data manipulation or exfiltration, LDAP credential harvesting. This attack appear to be exploitable via "network connectivity". Taking advantage of improper validation of security tokens in API endpoints. Please note this is a different issue than CVE-2018-10931.

The remote Redhat Enterprise Linux 8 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - cobbler: XMLRPC API endpoints are not correctly validating security tokens (CVE-2018-1000226)

  - Cobbler version Verified as present in Cobbler versions 2.6.11+, but code inspection suggests at least     2.0.0+ or possibly even older versions may be vulnerable contains a Cross Site Scripting (XSS)     vulnerability in cobbler-web that can result in Privilege escalation to admin.. This attack appear to be     exploitable via network connectivity. Sending unauthenticated JavaScript payload to the Cobbler XMLRPC     API (/cobbler_api). (CVE-2018-1000225)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

This plugin has been deprecated as it does not adhere to established standards for this style of check.

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)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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