CVE-2024-5441

HIGH EXPLOITED

Modern Events Calendar <= 7.11.0 - Arbitrary File Upload via set_featured_image Function

Title source: llm
STIX 2.1

Exploitation Summary

CVE-2024-5441 has been observed exploited in the wild (reported by VulnCheck KEV).

Description

The Modern Events Calendar plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the set_featured_image function in all versions up to, and including, 7.11.0. This makes it possible for authenticated attackers, with subscriber access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible. The plugin allows administrators (via its settings) to extend the ability to submit events to unauthenticated users, which would allow unauthenticated attackers to exploit this vulnerability.
