High severity GitHub Reviewed Published Mar 19, 2021 in xwiki/xwiki-platform • Updated Feb 1, 2023

Package

maven org.xwiki.platform:xwiki-platform-ratings-api (Maven)

Affected versions

Description

Impact

This issue impacts only XWiki with the Ratings API installed.
The Rating Script Service expose an API to perform SQL requests without escaping the from and where search arguments.
This might lead to an SQL script injection quite easily for any user having Script rights on XWiki.

Patches

The problem has been patched in XWiki 12.9RC1.

Workarounds

The only workaround besides upgrading XWiki would be to uninstall the Ratings API in XWiki from the Extension Manager.

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.
