Attack-Flow Graph

Executive Summary

The Eventin WordPress plugin before version 4.1.21 has a Local File Inclusion (LFI) vulnerability. This occurs because the plugin does not properly validate a template path value before using it to include a local file. Attackers with contributor-level access or higher can exploit this to include and execute arbitrary PHP files on the server.

Detection Guidance

Check the installed version of the Eventin WordPress plugin. If it is below 4.1.21, the system is vulnerable. Use commands like 'wp plugin list' in WordPress CLI or inspect the plugin files directly.

Impact Analysis

An attacker could gain control of your WordPress site by executing malicious PHP files. This could lead to unauthorized access, data theft, or further compromise of your server. The impact includes potential defacement, malware distribution, or unauthorized data modification.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating GDPR and HIPAA compliance. It may result in data breaches, unauthorized data exposure, or loss of data integrity, all of which are critical compliance violations.

Mitigation Strategies

Update the Eventin plugin to version 4.1.21 or later immediately. If updating is not possible, restrict contributor-level and higher user access to prevent exploitation.
