Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-379: Creation of Temporary File in Directory with Insecure Permissions, where the product creates a temporary file in a directory whose permissions allow unintended actors to determine the file's existence or otherwise access that file. In Moodle/moodle, 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 theme implementation in Moodle 2.0.x before 2.0.4 and 2.1.x before 2.1.1 triggers duplicate caching of Cascading Style Sheets (CSS) and JavaScript content, which allows remote attackers to bypass intended access restrictions and write to an operating-system temporary directory via unspecified vectors.
