> Missing escaping in MultiFileUploadField.js - sort of XSS
> ---------------------------------------------------------
>
> Key: WICKET-5782
> URL: https://issues.apache.org/jira/browse/WICKET-5782
> Project: Wicket
> Issue Type: Bug
> Affects Versions: 6.17.0
> Reporter: Martin Petricek
> Assignee: Martin Grigorov
> Fix For: 7.0.0-M5, 6.19.0
>
>
> When uploading files via
> org.apache.wicket.markup.html.form.upload.MultiFileUploadField component,
> names of uploaded files are added into a table.
> Inside MultiFileUploadField.js is line that adds names of files:
> {code}
> contentsColumn.innerHTML = this.getOnlyFileNames(element);
> {code}
> This code is missing any escaping, so if you upload file named:
> {code}
> <code onmouseover=alert(1)>.doc
> {code}
> and hover on the name, you trigger sort of an XSS.
> It is unlikely to be a real threat, as you can probably only attack yourself
> with this bug and it very uncommon to have files with "<" or ">" characters
> in their name, but "&" can be relatively common in names of files and "&"
> needs proper escaping too.
> So before adding the filename to contentsColumn.innerHtml, it needs to be
> properly escaped.
