WordPress Registration Vulnerability Allows Hackers to Inject Malicious Code

CVSScvssV3_1: 9.8

A critical vulnerability was discovered in the registration process of popular CMS WordPress. The CVE assigned is CVE-2023-44167 with a CVSS score of 9.8, making it a severe risk.

The issue arises in the ‘name’ parameter passed to process_registration.php. This field is not sanitized before inserting into the database. A malicious actor could pass SQL commands or JavaScript code instead of a name, allowing the injection of malicious code into the site.

This can have serious consequences. An attacker could use this to steal admin credentials, install malware, or deface the site. The compromised site could then be used to launch phishing attacks or spread malware to visitors.

If you are a WordPress site owner, you should update WordPress and all plugins immediately. Keeping everything updated is one of the best ways to patch vulnerabilities. You can also consider using a web application firewall to filter malicious inputs.

Users should be cautious visiting any sites running an outdated version of WordPress until their administrators patch the vulnerability. Updating and practicing basic security hygiene is important for all websites to protect visitors from these types of attacks.
