CVE-2017-16615 (GCVE-0-2017-16615)

Vulnerability from cvelistv5 – Published: 2017-11-08 03:00 – Updated: 2024-08-05 20:27

Summary

An exploitable vulnerability exists in the YAML parsing functionality in the parse_yaml_query method in parser.py in MLAlchemy before 0.2.2. When processing YAML-Based queries for data, a YAML parser 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.

Severity ?

No CVSS data available.
