CVE-2025-4336: 
WordPress vulnerability analysis and mitigation

The eMagicOne Store Manager for WooCommerce plugin for WordPress contains a critical vulnerability (CVE-2025-4336) affecting all versions up to and including 1.2.5. The vulnerability was discovered in May 2025 and allows unauthenticated attackers to upload arbitrary files to the affected site's server through the set_file() function due to missing file type validation (NVD CVE).

The vulnerability exists in the plugin's remote management protocol endpoint (?connector=bridge) that handles file uploads. The authentication mechanism relies on default credentials (login=1, password=1) and a session key system. The vulnerability stems from the set_file() function in class-emosmcwoocommerceoverrider.php which lacks proper file type validation. An attacker can exploit this by first obtaining a session key using the default credentials, then uploading arbitrary files to any writable directory on the server (Ryan Blog).

The vulnerability allows unauthenticated attackers to upload arbitrary files, including PHP shells, to the WordPress root directory or any writable directory on the server. This could lead to remote code execution on the affected site. The vulnerability is particularly dangerous when the default authentication credentials (1:1) are left unchanged (NVD CVE).

Site administrators should immediately update their eMagicOne Store Manager for WooCommerce plugin to a version newer than 1.2.5 when available. As an immediate mitigation, administrators should change the default authentication credentials from their default values (1:1) to strong, unique credentials (NVD CVE).
