The Modern Events Calendar Lite plugin is a popular WordPress plugin used to manage events and calendars on websites. It is a free and easy-to-use plugin that enables website owners to display various events, such as conferences, festivals, concerts, and more, on their website.
However, researchers recently discovered a serious vulnerability in the plugin, known as CVE-2021-24145. This vulnerability allows an attacker to upload arbitrary files to the website, bypassing the security checks and authorization mechanisms. This means that an attacker can upload malicious PHP files, leading to remote code execution and a potential compromise of the website.
When exploited, this vulnerability can lead to various negative consequences for both the website owner and the website visitors. An attacker can use the uploaded file to gain control of the website, steal sensitive data, or install malware on the website, which can then infect visitors' devices. This can lead to data breaches, financial losses, and reputational damage for the website owner, and security risks for the users.
