Overview
jw.util is a package for version handling, YAML configuration and file renaming with various backup strategies.
Affected versions of this package are vulnerable to Remote Code Execution (RCE). An exploitable vulnerability exists in the configuration-loading functionality of the jw.util package before 2.3 for Python. When loading a configuration with FromString or FromStream with YAML, one can execute arbitrary Python code, resulting in OS command execution, because safe_load
is not used.
