Several security issues were fixed in Cobbler.

Software Description:
- cobbler: Cobbler is a versatile Linux deployment server

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)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 16.04 LTS (Available with Ubuntu Pro):
   cobbler                         2.4.1-0ubuntu2+esm1
   cobbler-common                  2.4.1-0ubuntu2+esm1
   cobbler-web                     2.4.1-0ubuntu2+esm1
   koan                            2.4.1-0ubuntu2+esm1
   python-cobbler                  2.4.1-0ubuntu2+esm1
   python-koan                     2.4.1-0ubuntu2+esm1
