Title

org.xwiki.platform:xwiki-platform-rendering-macro-rss Cross-site Scripting vulnerability

Summary

XWiki Commons are technical libraries common to several other top level XWiki projects. The RSS macro that is bundled in XWiki included the content of the feed items without any cleaning in the HTML output when the parameter `content` was set to `true`. This allowed arbitrary HTML and in particular also JavaScript injection and thus cross-site scripting (XSS) by specifying an RSS feed with malicious content. With the interaction of a user with programming rights, this could be used to execute arbitrary actions in the wiki, including privilege escalation, remote code execution, information disclosure, modifying or deleting content and sabotaging the wiki. The issue has been patched in XWiki 14.6 RC1, the content of the feed is now properly cleaned before being displayed. As a workaround, if the RSS macro isn't used in the wiki, the macro can be uninstalled by deleting `WEB-INF/lib/xwiki-platform-rendering-macro-rss-XX.jar`, where `XX` is XWiki's version, in the web application's directory.

GHSA-C885-89FW-55QR

Vulnerability from github – Published: 2023-04-12 20:38 – Updated: 2023-04-25 21:47

Summary

org.xwiki.platform:xwiki-platform-rendering-macro-rss Cross-site Scripting vulnerability

Details

Impact

The RSS macro that is bundled in XWiki included the content of the feed items without any cleaning in the HTML output when the parameter content was set to true. This allowed arbitrary HTML and in particular also JavaScript injection and thus cross-site scripting (XSS) by specifying an RSS feed with malicious content. With the interaction of a user with programming rights, this could be used to execute arbitrary actions in the wiki, including privilege escalation, remote code execution, information disclosure, modifying or deleting content and sabotaging the wiki.

The issue can be reproduced by inserting the following XWiki syntax in any wiki page like the user account:

{{rss feed="https://xssrss.blogspot.com/feeds/posts/default?alt=rss" content="true" /}}

If an alert is displayed when viewing the page, the wiki is vulnerable.

Patches

The issue has been patched in XWiki 14.6 RC1, the content of the feed is now properly cleaned before being displayed.

Workarounds

If the RSS macro isn't used in the wiki, the macro can be uninstalled by deleting WEB-INF/lib/xwiki-platform-rendering-macro-rss-XX.jar, where XX is XWiki's version, in the web application's directory.
