org.xwiki.platform:xwiki-platform-oldcore Open Redirect vulnerability

Moderate severity GitHub Reviewed Published May 15, 2023 in xwiki/xwiki-platform • Updated Nov 5, 2023

Package

maven org.xwiki.platform:xwiki-platform-oldcore (Maven)

Affected versions

< 14.10.4

Patched versions

14.10.4

Description

Impact

It's possible to exploit well known parameters in XWiki URLs to perform redirection to untrusted site. This vulnerability was partially fixed in the past for XWiki 12.10.7 and 13.3RC1 but there is still the possibility to force specific URLs to skip some checks, e.g. using URLs like http:example.com in the parameter would allow the redirect.

Patches

The issue has now been patched against all patterns that we know about for performing redirect. It also performs a real URI parsing that should protect in most cases. This has been patched in XWiki 14.10.4 and 15.0.

Workarounds

The only workaround is to upgrade XWiki.

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.
