> URL: https://issues.apache.org/jira/browse/JSPWIKI-5
> Project: JSPWiki
> Issue Type: Bug
> Components: Core & storage
> Affects Versions: 2.5.139-beta
> Environment: Ubuntu Linux, JDK 1.5
> Reporter: Janne Jalkanen
> Assignee: Janne Jalkanen
> Fix For: 2.8

>
> By manipulating the JSP fields directly, it's possible to upload a file (e.g.
> ".."), which ends up in the page directory under the name "..-att". This
> does not otherwise affect JSPWiki operation, but it does make that data
> inaccessible and invisible.
> Proposal is to make sure that dots should also be escaped when saving a file.
