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.

Detection & IOCsextracted from sources · hover to see the quote

  • The attack vector targets the 'first name' or 'last name' fields during user registration — monitor/block template injection payloads in these registration form fields
  • Only installations with guest user registration enabled are exploitable — audit XWiki instances for open registration and prioritize patching or disabling guest registration as a mitigation
  • Patch thresholds for detection/response triage: flag unpatched XWiki instances running versions below 14.10.17, 15.5.3, or 15.8 RC1 as vulnerable
  • ·Vulnerability is only exploitable when guest user registration is enabled; instances with registration disabled are not affected
