Vendor statement (Portabilis)

This stored XSS via SVG upload has been fixed in i-Diário.

The attachment uploader now rejects files whose declared content type indicates executable or markup content: image/svg+xml, text/html and application/xhtml+xml are rejected. In addition, the ".svg" extension is not part of the allowed-extension list, so SVG files are blocked regardless of the declared content type. All responses are served with the HTTP header "X-Content-Type-Options: nosniff".

As a result, a crafted SVG file containing embedded JavaScript can no longer be uploaded, nor served in a way that would execute script in the victim's browser.

The fix is available in the project's public repository, in commit https://github.com/portabilis/i-diario/commit/6c529bb2d96130aa29533f49e204e86518e11fdd

Recommended action: update to a current release of i-Diário.
