CVE-2025-5058 is a critical vulnerability identified in the eMagicOne Store Manager for WooCommerce WordPress plugin, affecting all versions up to and including 1.2.5. The vulnerability stems from improper file type validation in the set_image() function, which allows unauthenticated attackers to upload arbitrary files to the affected server. This is classified under CWE-434, indicating an unrestricted upload of files with dangerous types. The core issue is that the plugin does not sufficiently restrict or validate the types of files that can be uploaded, enabling attackers to potentially upload malicious scripts or executables. Exploitation can lead to remote code execution (RCE), allowing attackers to execute arbitrary commands on the server, compromising confidentiality, integrity, and availability of the system. However, exploitation requires either the default weak password (1:1) to remain unchanged or the attacker to have obtained valid credentials, which limits the attack vector to misconfigured or poorly secured installations. The vulnerability has a CVSS v3.1 base score of 9.8, reflecting its critical nature with network attack vector, low attack complexity, no privileges required, and no user interaction needed. Although no known exploits are currently reported in the wild, the potential impact is severe due to the possibility of full system compromise through remote code execution. The lack of a patch at the time of disclosure further elevates the risk for affected users.

For European organizations using the eMagicOne Store Manager for WooCommerce plugin, this vulnerability poses a significant threat. Successful exploitation could lead to full server compromise, data breaches involving customer and transactional data, defacement of e-commerce sites, disruption of business operations, and potential lateral movement within corporate networks. Given the critical CVSS score and the possibility of remote code execution without authentication under certain conditions, attackers could deploy ransomware, steal sensitive information, or use compromised servers as a foothold for broader attacks. The impact is particularly concerning for small and medium-sized enterprises (SMEs) that may lack robust security practices, including changing default credentials. Additionally, organizations in regulated sectors such as finance, healthcare, and retail could face compliance violations and reputational damage if customer data is exposed or services disrupted. The e-commerce focus of the plugin means that availability and integrity of online sales platforms are at risk, potentially leading to financial losses and erosion of customer trust.

To mitigate this vulnerability, European organizations should immediately audit their WordPress installations for the presence of the eMagicOne Store Manager for WooCommerce plugin and verify the version in use. If affected versions are detected, organizations should implement the following specific measures: 1) Change any default or weak passwords associated with the plugin or WordPress admin accounts to strong, unique credentials to prevent unauthorized access. 2) Restrict file upload permissions and implement web application firewall (WAF) rules to detect and block suspicious file uploads targeting the set_image() function or related endpoints. 3) Employ strict server-side file type validation and filtering mechanisms to prevent execution of uploaded files, including disabling execution permissions in upload directories. 4) Monitor server logs and WordPress activity for unusual file upload attempts or unexpected administrative actions. 5) Isolate the affected WordPress instances in network segments with limited access to reduce lateral movement risk. 6) Engage with the vendor or community to obtain patches or updates as soon as they become available and apply them promptly. 7) Consider temporary disabling or uninstalling the plugin if immediate patching is not possible. 8) Conduct regular security assessments and penetration tests focusing on file upload functionalities to identify similar weaknesses.
