CVE-2017-16618
An exploitable vulnerability exists in the YAML loading functionality of util.py in OwlMixin before 2.0.0a12.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.47%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
An exploitable vulnerability exists in the YAML loading functionality of util.py in OwlMixin before 2.0.0a12. A "Load YAML" string or file (aka load_yaml or load_yamlf) can execute arbitrary Python commands resulting in command execution because load is used where safe_load should have been used. An attacker can insert Python into loaded YAML to trigger this vulnerability.
