Description
Unrestricted Upload of File with Dangerous Type vulnerability in Ovatheme Ovatheme Events Manager allows Using Malicious Files.This issue affects Ovatheme Events Manager: from n/a through 1.8.4.
Analysis
CVE-2025-32510 is an unrestricted file upload vulnerability in Ovatheme Events Manager versions up to 1.8.4 that allows unauthenticated attackers to upload malicious files, achieving remote code execution and complete system compromise. With a perfect CVSS 10.0 score, network-accessible attack vector, and no authentication required, this vulnerability poses critical risk to all exposed installations. Exploitation is trivial and requires only HTTP requests.
Technical Context
This vulnerability stems from CWE-434 (Unrestricted Upload of File with Dangerous Type), a class of file handling flaws where an application fails to properly validate file types before storage and execution. The Ovatheme Events Manager plugin, a WordPress events management extension (CPE: ovatheme:events_manager), implements file upload functionality without adequate type validation, file extension whitelisting, or execution prevention in upload directories. Attackers bypass client-side and weak server-side filters to upload executable files (PHP, JSP, ASPX, etc.) to web-accessible directories, enabling arbitrary code execution within the application's security context. The vulnerability affects all versions from initial release through 1.8.4, suggesting the flaw existed from the feature's inception.
Affected Products
Ovatheme Events Manager (1.0 through 1.8.4)
Remediation
Immediate Action: DISABLE the Ovatheme Events Manager plugin immediately via WordPress admin dashboard (Plugins > Deactivate) until patch availability is confirmed Detection: Scan web server upload directories (typically /wp-content/uploads/) for recently created executable files (.php, .phtml, .php3, .php4, .php5, .phar, .shtml, .jsp, .jspx, .jsw, .jsv, .jspf, .aspx, .asp, .cer, .asa) with creation/modification dates after plugin installation Forensics: Review web server access logs (Apache access.log, Nginx access.log) for POST requests to upload endpoints and subsequent GET requests to suspicious file paths created within upload directories Web Application Firewall: If plugin must remain temporarily active, implement WAF rules blocking file uploads with executable extensions and restricting access to upload directories to known-safe file types only File System Hardening: Configure upload directories with PHP execution disabled (via .htaccess 'php_flag engine off' for Apache, or location blocks for Nginx) to prevent execution of uploaded malicious files Patch/Upgrade: Monitor Ovatheme security advisories and WordPress plugin repository for patched versions above 1.8.4; apply immediately upon availability Alternative: If vendor does not provide timely patches, replace Ovatheme Events Manager with actively maintained alternatives (e.g., The Events Calendar, Eventbrite, or Caldera Forms)
