Code Execution Vulnerability Discovered in Yamale Python Package, Impacting Over 200 Projects
On October 7, 2021, a serious code injection vulnerability was identified in Yamale, a schema and validator for YAML files developed by 23andMe. This flaw could be easily exploited by attackers to execute arbitrary Python code. Designated as CVE-2021-38305 with a CVSS score of 7.8, the vulnerability arises from the improper handling of the schema file input, enabling circumvention of security measures.
The issue lies within the schema parsing function, which inadequately evaluates and executes all inputs, allowing maliciously crafted strings to execute system commands. Yamale is widely utilized by developers for validating YAML, a data serialization language commonly used in configuration files, with at least 224 repositories on GitHub relying on this package. This vulnerability presents a significant risk for any projects that utilize input schema files, enabling potential Python code injection for those with access.
