發布日:2023/6/22修改日:2023/11/8

描述

### Impact Users are able to forge an URL with a payload allowing to inject Javascript in the page (XSS). It's possible to exploit the resubmit template to perform a XSS, e.g. by using URL such as: > xwiki/bin/view/XWiki/Main?xpage=resubmit&resubmit=javascript:alert(document.domain)&xback=javascript:alert(document.domain) This vulnerability exists since XWiki 2.5-milestone-2. ### Patches The vulnerability has been patched in XWiki 14.10.5 and 15.1-rc-1. ### Workarounds It's possible to workaround the vulnerability by editing the template resubmit.vm to perform checks on it, but note that the appropriate fix involves new APIs that have been recently introduced in XWiki. See the referenced jira tickets. ### References * Jira ticket about the vulnerability: https://jira.xwiki.org/browse/XWIKI-20343 * Introduction of the macro used for fixing all those vulnerabilities: https://jira.xwiki.org/browse/XWIKI-20583 * Commit containing the actual fix in the page: https://github.com/xwiki/xwiki-platform/commit/dbc92dcdace33823ffd1e1591617006cb5fc6a7f ### For more information If you have any questions or comments about this advisory: * Open an issue in [Jira XWiki.org](https://jira.xwiki.org/) * Email us at [Security Mailing List](mailto:[email protected]) ### Attribution This vulnerability has been reported by René de Sain @renniepak.
