CVE-2025-57148 identifies a security vulnerability in the phpgurukul Online Shopping Portal 2.0, specifically within the /admin/insert-product.php script. The vulnerability is an Arbitrary File Upload flaw caused by the absence of proper file extension validation during the product insertion process. This lack of validation allows an attacker with access to the admin interface to upload files of any type, including potentially malicious scripts or executables. Such files could be used to execute arbitrary code on the server, leading to unauthorized access, data theft, or server compromise. Although the affected versions are not explicitly specified, the vulnerability is tied to the 2.0 version of the portal. No official patch or mitigation has been published yet, and there are no known exploits in the wild at this time. The vulnerability was reserved on August 17, 2025, and published on September 3, 2025. The absence of a CVSS score requires an independent severity assessment based on the impact and exploitability factors.

For European organizations using phpgurukul Online Shopping Portal 2.0, this vulnerability poses a significant risk. If exploited, attackers could upload malicious files that may lead to full server compromise, data breaches involving customer and transactional data, and disruption of e-commerce operations. The confidentiality of sensitive customer information could be jeopardized, and the integrity of the online shopping platform could be undermined, potentially damaging brand reputation and customer trust. Availability could also be affected if attackers deploy ransomware or other destructive payloads. Given the administrative nature of the vulnerable endpoint, exploitation requires some level of access, but if administrative credentials are weak or compromised, the risk escalates. The lack of extension validation is a common and critical security oversight that can be leveraged for persistent attacks and lateral movement within the network.

European organizations should immediately audit their phpgurukul Online Shopping Portal 2.0 installations to identify if the vulnerable /admin/insert-product.php script is in use. Until an official patch is released, organizations should implement strict file upload controls, including server-side validation of file types and extensions, and whitelist acceptable file formats. Employing web application firewalls (WAFs) to detect and block suspicious file upload attempts can provide an additional layer of defense. Access to the admin interface should be restricted using multi-factor authentication (MFA), IP whitelisting, and strong password policies to reduce the risk of credential compromise. Regular monitoring of server logs for unusual file uploads or execution attempts is critical. Organizations should also consider isolating the upload directory with limited permissions and disabling execution rights on uploaded files to prevent code execution. Finally, maintaining regular backups and an incident response plan will help mitigate damage in case of exploitation.
