CVE-2022-36094 Published on September 8, 2022
XWiki Platform Web Parent POM vulnerable to XSS in the attachment history
XWiki Platform Web Parent POM contains Web resources for the XWiki platform, a generic wiki platform. Starting with version 1.0 and prior to versions 13.10.6 and 14.30-rc-1, it's possible to store JavaScript which will be executed by anyone viewing the history of an attachment containing javascript in its name. This issue has been patched in XWiki 13.10.6 and 14.3RC1. As a workaround, it is possible to replace `viewattachrev.vm`, the entry point for this attack, by a patched version from the patch without updating XWiki.

Weakness Types
What is a XSS Vulnerability?
The software 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.
CVE-2022-36094 has been classified to as a XSS vulnerability or weakness.
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.
