Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In Moin, 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

Multiple cross-site scripting (XSS) vulnerabilities in `action/AttachFile.py` in MoinMoin 1.5.8 and earlier allow remote attackers to inject arbitrary web script or HTML via (1) message, (2) pagename, and (3) target filenames.
