Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-1236: Improper Neutralization of Formula Elements in a CSV File, where the product saves user-provided information into a comma-separated value (csv) file, but it does not neutralize or incorrectly neutralizes special elements that could be interpreted as a command when the file is opened by a spreadsheet product. In Moodle/moodle, software state validation or input boundaries are circumvented during processing.
