Detailsinfo

A vulnerability classified as critical has been found in xwiki-platform up to 11.x/12.6/16.4.6/16.10.2. Affected is an unknown code. The manipulation with an unknown input leads to a code injection vulnerability. CWE is classifying the issue as CWE-94. The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

XWiki is a generic wiki platform. Any user with edit right on a page (could be the user's profile) can execute code (Groovy, Python, Velocity) with programming right by defining a wiki macro. This allows full access to the whole XWiki installation. The main problem is that if a wiki macro parameter allows wiki syntax, its default value is executed with the rights of the author of the document where it is used. This can be exploited by overriding a macro like the children macro that is used in a page that has programming right like the page XWiki.ChildrenMacro and thus allows arbitrary script macros. This vulnerability has been patched in XWiki 16.4.7, 16.10.3 and 17.0.0 by executing wiki parameters with the rights of the wiki macro's author when the parameter's value is the default value.
