Event Banner <= 1.3 - Cross-Site Request Forgery

7.2
Cross-Site Request Forgery (CSRF)
CVE CVE-2021-24252
CVSS 7.2 (High)
Publicly Published April 10, 2021
Last Updated February 3, 2023
Researcher Jin Huang

Description

The Event Banner WordPress plugin through 1.3 does not verify the uploaded image file, allowing admin accounts to upload arbitrary files, such as .exe, .php, or others executable, leading to RCE. Due to the lack of CSRF check, the issue can also be used via such vector to achieve the same result, or via a LFI as authorisation checks are missing (but would require WP to be loaded)
