Details

As written in the advisory (Markdown source, shown as plain text).

### Impact Any user with view rights `WikiManager.DeleteWiki` can execute arbitrary Groovy, Python or Velocity code in XWiki leading to full access to the XWiki installation. The root cause is improper escaping of the `wikiId` url parameter. A proof of concept exploit is to open <xwiki-host>/xwiki/bin/view/WikiManager/DeleteWiki?wikiId=%22+%2F%7D%7D+%7B%7Basync+async%3D%22true%22+cached%3D%22false%22+context%3D%22doc.reference%22%7D%7D%7B%7Bgroovy%7D%7Dprintln%28%22Hello+from+groovy%21%22%29%7B%7B%2Fgroovy%7D%7D%7B%7B%2Fasync%7D%7D where <xwiki-host> is the URL of your XWiki installation. ### Patches The problem has been patched on XWiki 13.10.11, 14.4.7, and 14.10. ### Workarounds The issue can be fixed manually applying this [patch](https://github.com/xwiki/xwiki-platform/commit/ba4c76265b0b8a5e2218be400d18f08393fe1428#diff-64f39f5f2cc8c6560a44e21a5cfd509ef00e8a2157cd9847c9940a2e08ea43d1R63-R64).
