Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-20: Improper Input Validation, where the product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. In Github.com/prasmussen/glot code runner, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

The default configuration of glot-www through 2018-05-19 allows remote attackers to execute arbitrary code because glot-code-runner supports os.system within a "python" "files" "content" JSON file.
