Cross-site Scripting in Filter Stream Converter Application in XWiki Platform
XWiki Platform Filter UI provides a generic user interface to convert from a XWiki Filter input stream to an output stream with settings for each stream. Starting with versions 6.0-milestone-2 and 5.4.4 and prior to versions 12.10.11, 14.0-rc-1, 13.4.7, and 13.10.3, XWiki Platform Filter UI contains a possible cross-site scripting vector in the `Filter.FilterStreamDescriptorForm` wiki page related to pretty much all the form fields printed in the home page of the application. The issue is patched in versions 12.10.11, 14.0-rc-1, 13.4.7, and 13.10.3. The easiest workaround is to edit the wiki page `Filter.FilterStreamDescriptorForm` (with wiki editor) according to the instructions in the GitHub Security Advisory.

Weakness Types
What is a Basic XSS Vulnerability?
The software receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special characters such as "<", ">", and "&" that could be interpreted as web-scripting elements when they are sent to a downstream component that processes web pages. This may allow such characters to be treated as control characters, which are executed client-side in the context of the user's session. Although this can be classified as an injection problem, the more pertinent issue is the improper conversion of such special characters to respective context-appropriate entities before displaying them to the user.
CVE-2022-29258 has been classified to as a Basic XSS vulnerability or weakness.
What is an Output Sanitization Vulnerability?
The software prepares a structured message for communication with another component, but encoding or escaping of the data is either missing or done incorrectly. As a result, the intended structure of the message is not preserved.
CVE-2022-29258 has been classified to as an Output Sanitization vulnerability or weakness.
