CVE-2024-21650 Published on January 8, 2024
XWiki Remote Code Execution vulnerability via user registration
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.

The potential impact of an exploit of this vulnerability is considered to be critical as this vulnerability has a high impact to the confidentiality, integrity and availability of this component.
Weakness Type
What is an Eval Injection Vulnerability?
The software receives input from an upstream component, but it does not neutralize or incorrectly neutralizes code syntax before using the input in a dynamic evaluation call (e.g. "eval"). This may allow an attacker to execute arbitrary code, or at least modify what code can be executed.
CVE-2024-21650 has been classified to as an Eval Injection vulnerability or weakness.
