Summary

Cross-site Scripting in org.xwiki.commons:xwiki-commons-xml

Details

Impact

The "restricted" mode of the HTML cleaner in XWiki, introduced in version 4.2-milestone-1 and massively improved in version 14.6-rc-1, allowed the injection of arbitrary HTML code and thus cross-site scripting via invalid HTML comments. As a consequence, any code relying on this "restricted" mode for security is vulnerable to JavaScript injection ("cross-site scripting"/XSS). An example are anonymous comments in XWiki where the HTML macro filters HTML using restricted mode:

{{html}}
<!--> <Details Open OnToggle=confirm("XSS")>
{{/html}}

When a privileged user with programming rights visits such a comment in XWiki, the malicious JavaScript code is executed in the context of the user session. This allows server-side code execution with programming rights, impacting the confidentiality, integrity and availability of the XWiki instance.

Note that while all versions since 4.2-milestone-1 should be vulnerable, only starting with version 14.6-rc-1 the HTML comment is necessary for the attack to succeed due to another vulnerability that has been patched in version 14.6-rc-1.

Patches

This problem has been patched in XWiki 14.10, HTML comments are now removed in restricted mode and a check has been introduced that ensures that comments don't start with >.

Workarounds

There are no known workarounds apart from upgrading to a version including the fix.

CVE-2023-29528 (GCVE-0-2023-29528)

Vulnerability from cvelistv5 – Published: 2023-04-20 17:08 – Updated: 2025-02-04 21:35

Title

Cross-site Scripting in org.xwiki.commons:xwiki-commons-xml

Summary

XWiki Commons are technical libraries common to several other top level XWiki projects. The "restricted" mode of the HTML cleaner in XWiki, introduced in version 4.2-milestone-1 and massively improved in version 14.6-rc-1, allowed the injection of arbitrary HTML code and thus cross-site scripting via invalid HTML comments. As a consequence, any code relying on this "restricted" mode for security is vulnerable to JavaScript injection ("cross-site scripting"/XSS). When a privileged user with programming rights visits such a comment in XWiki, the malicious JavaScript code is executed in the context of the user session. This allows server-side code execution with programming rights, impacting the confidentiality, integrity and availability of the XWiki instance. This problem has been patched in XWiki 14.10, HTML comments are now removed in restricted mode and a check has been introduced that ensures that comments don't start with `>`. There are no known workarounds apart from upgrading to a version including the fix.
