AI-suggested
European organizations should immediately upgrade the xwiki-contrib macro-fullcalendar component to version 2.4.5 or later, where the vulnerability is patched. Until patching is possible, restrict access to the Calendar.JSONService page by implementing strict access controls, such as IP whitelisting or authentication enforcement, to prevent guest or unauthorized user access. Employ web application firewalls (WAFs) with SQL injection detection and prevention rules tailored to XWiki traffic patterns. Conduct thorough audits of XWiki installations to identify vulnerable versions and monitor logs for suspicious activity targeting the Calendar.JSONService endpoint. Additionally, implement network segmentation to isolate critical wiki infrastructure and enforce the principle of least privilege for users accessing wiki services. Regularly review and update security policies to include prompt patch management and vulnerability scanning for third-party components like XWiki macros.
Description
XWiki Full Calendar Macro displays objects from the wiki on the calendar. Prior to version 2.4.5, users with the right to view the Calendar.JSONService page (including guest users) can exploit a SQL injection vulnerability by accessing database info or starting a DoS attack. This issue has been patched in version 2.4.5.
