Cobbler vulnerable to code injection via unsafe YAML loading

  • Disclosed: 17.05.2022
  • Updated: 11.10.2026 13:18

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.
