Update Your XWiki Installation to Patch Remote Code Execution Vulnerability

CVSScvssV3_1: 10

XWiki is a popular open source wiki platform that many websites and companies use to build collaborative applications and websites. Unfortunately, researchers discovered a serious vulnerability in XWiki that could allow remote attackers to execute code on servers running vulnerable versions.

The vulnerability is located in XWiki’s user registration feature. By crafting malicious input in the first or last name fields during registration, an attacker could execute arbitrary code on the server. This gives the attacker full control of the server and puts sites at risk.

To exploit the vulnerability, an attacker would simply need to complete the registration form with a specially crafted payload in the name fields. No other interaction or authentication would be required. This makes the vulnerability very dangerous.

The good news is that XWiki developers have addressed the issue and released patched versions. All XWiki users are advised to update their installations immediately to XWiki 14.10.17, 15.5.3 or 15.8 RC1. These versions fix the remote code execution vulnerability.

It is critical that sites using XWiki take action now to protect themselves from this serious vulnerability. Updating to the latest patched version of XWiki helps prevent remote attackers from gaining control of servers. Staying on top of software updates is one of the best ways to help secure systems from cyber threats.
