The set_mgmt_parameters function in item.py in cobbler before 2.2.2 allows context-dependent attackers to execute arbitrary code via vectors related to the use of the yaml.load function instead of the yaml.safe_load function, as demonstrated using Puppet.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - The set_mgmt_parameters function in item.py in cobbler before 2.2.2 allows context-dependent attackers to

  - build server wants explicite package in BuildRequires;
    use tftp

  - fix service restart after logrotate for cobblerd     (boo#1113747)

  - rotate cobbler logs at higher frequency to prevent disk     fillup (boo#1113747)

  - Forbid exposure of private methods in the API     (CVE-2018-10931) (CVE-2018-1000225) (boo#1104287)     (boo#1104189) (boo#1105442)

  - Check access token when calling 'modify_setting' API     endpoint (boo#1104190) (boo#1105440) (CVE-2018-1000226)
