XWiki programming rights may be inherited by inclusion

Critical severity GitHub Reviewed Published Jun 24, 2024 in xwiki/xwiki-platform • Updated Jun 24, 2024

Package

maven org.xwiki.platform:xwiki-platform-rendering-macro-include (Maven)

Affected versions

< 15.0-rc-1

Patched versions

15.0-rc-1

Description

Impact

The content of a document included using {{include reference="targetdocument"/}} is executed with the right of the includer and not with the right of its author.

This means that any user able to modify the target document can impersonate the author of the content which used the include macro.

Patches

This has been patched in XWiki 15.0 RC1 by making the default behavior safe.

Workarounds

Make sure to protect any included document to make sure only allowed users can modify it.

A workaround have been provided in 14.10.2 to allow forcing to execute the included content with the target content author instead of the default behavior. See https://extensions.xwiki.org/xwiki/bin/view/Extension/Include%20Macro#HAuthor for more details.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
