BizCalendar Web plugin for WordPress | Up to and including 1.1.0.50<\/p>\n

How the Exploit Works<\/strong><\/p>\n

An attacker with Contributor-level access can exploit this vulnerability by using the ‘bizcalv’ shortcode, which is vulnerable to Local File Inclusion. By manipulating the shortcode, an attacker can include and execute arbitrary files on the server. If the attacker can upload and include PHP files or other \u201csafe\u201d file types like images, they can execute arbitrary PHP code in those files. This could allow the attacker to bypass access controls, obtain sensitive data, or even execute code on the server.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Below is a conceptual example of how the vulnerability might be exploited. In this scenario, the attacker utilizes the ‘bizcalv’ shortcode to include a malicious PHP file.<\/p>\n

POST \/wp-admin\/admin-ajax.php?action=bizcalendar_render&bizcalv=\/..\/..\/..\/..\/malicious.php HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/x-www-form-urlencoded\n{ \"shortcode\": \"[bizcalv]\" }<\/code><\/pre>\n
Mitigation Guidance<\/strong><\/p>\n
The recommended mitigation strategy is to apply the vendor patch as soon as it is available. In the meantime, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can serve as a temporary mitigation measure.<\/p>\n","protected":false},"excerpt":{"rendered":"
