SourceCVE-2023-50851

N Squared Appointment Booking Calendar — Simply Schedule Appointments Booking Plugin was found to have a SQL Injection vulnerability. SQL Injection is a type of injection attack where malicious SQL statements are inserted into an entry field for execution by the backend database.

This plugin allows users to book and manage appointments through a calendar interface on websites. However, if certain special characters were not sanitized properly on the backend, a malicious user could have crafted SQL queries to extract or manipulate data in the database.

Some attacks that could be performed include viewing sensitive data like user accounts or passwords, changing data, deleting database content or adding new accounts. All of this is possible by abusing the interaction between the website’s entry fields and the backend database.

The good news is that the plugin developers have released an update, version 1.6.6.1, to fix this security issue. All users of the N Squared Appointment Booking Calendar plugin are advised to update to the latest version immediately to protect their website and user data from any potential SQL Injection attacks.

Proper input validation and output encoding is important for any application that interacts with a database. Keeping software updated is also key to using the latest patches for known vulnerabilities.
