XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. XWiki is vulnerable to a remote code execution (RCE) attack through its user registration feature. This issue allows an attacker to execute arbitrary code by crafting malicious payloads in the "first name" or "last name" fields during user registration. This impacts all installations that have user registration enabled for guests. This vulnerability has been patched in XWiki 14.10.17, 15.5.3 and 15.8 RC1.

XWiki Platform versions from 2.2 before 14.10.17, from 15.0-rc-1 before 15.5.3, and from 15.6-rc-1 before 15.8-rc-1 suffer from a Server-Side Template Injection (SSTI) due to the lack of sanitization of the user registration form's inputs. By leveraging this vulnerability, a remote and unauthenticated attacker can achieve privilege escalation and achieve code execution on the vulnerable XWiki instance.

There are packages installed that are affected by a vulnerability referenced in the following CVE:
