Summary
starcitizentools/citizen-skin allows stored XSS in search no result messages
Details

Summary

The citizen-search-noresults-title and citizen-search-noresults-desc system messages are inserted into raw HTML, allowing anybody who can edit those messages to insert arbitrary HTML into the DOM.

Details

The system messages are inserted as raw HTML by the mustache template: https://github.com/StarCitizenTools/mediawiki-skins-Citizen/blob/407052e7069bdeae927d6f1a2a1c9a45b473bf9a/resources/skins.citizen.search/templates/TypeaheadPlaceholder.mustache#L8-L9

PoC

  1. Edit citizen-search-noresults-title and citizen-search-noresults-desc to <img src="" onerror="alert('citizen-search-noresults-title')"> and <img src="" onerror="alert('citizen-search-noresults-desc')"> (script tags don't work here due to the way the HTML is inserted)
  2. Open the search bar and search for a page that doesn't exist to get the "no results" messages to show up
