Impact

The Ovatheme Events Manager WordPress plugin allows unauthenticated users to upload any file because the process_checkout() function fails to validate the file type. An attacker can place malicious code on the server, potentially enabling remote code execution. This flaw is classified as CWE-434.

Affected Systems

The vulnerability affects all installations of the Ovatheme Events Manager WordPress plugin up to and including version 1.8.5. Sites running that version or older are vulnerable.

Risk and Exploitability

With a CVSS score of 9.8, the flaw is considered critical. The EPSS score is below 1%, indicating a very low expected exploitation rate, and it is not currently listed in the CISA KEV catalog. Attackers can exploit the flaw by sending a crafted file through the exposed process_checkout endpoint without authentication.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Verify the current plugin version and check with the vendor for a disclosed fix. Apply any available update that addresses this issue.
  • Prevent execution of files stored in the plugin’s upload directory by configuring web‑server directives (e.g., setting the directory to static content, using .htaccess rules or web.config) or by removing execute permissions.
  • Restrict or disable the /process_checkout endpoint for unauthenticated requests using web‑server rules, plugin settings, or by requiring authentication. This limits the ability to submit arbitrary files.
  • Continuously monitor upload directories and web‑server logs for unauthorized file uploads, and deploy a web‑application firewall or similar controls to detect and block malicious upload attempts.
