xwiki-platform vulnerable to Remote Code Execution in Annotations

Critical severity GitHub Reviewed Published Mar 1, 2023 in xwiki/xwiki-platform • Updated Mar 13, 2023

Package

maven org.xwiki.platform:xwiki-platform-annotation-ui (Maven)

Affected versions

>= 2.3-milestone-1, < 13.10.11
>= 14.0-rc-1, < 14.4.7
>= 14.5, < 14.10

Patched versions

13.10.11
14.4.7
14.10

Description

Impact

The annotation displayer does not execute the content in a restricted context. This allows executing anything with the right of the author of any document by annotating the document.

To reproduce: add an annotation with the content {{groovy}}print "hello"{{/groovy}} and click the yellow scare to get a display of the annotation inline.

The result is "hello" but it should be an error suggesting that it's not allowed to use the groovy macro.

Patches

This has been patched in XWiki 13.10.11, 14.4.7 and 14.10.

Workarounds

There is no easy workaround except to upgrade.

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.
