CVE-2025-10616 is a medium-severity vulnerability affecting version 1.0 of the itsourcecode E-Commerce Website platform. The flaw resides in an unspecified function within the /admin/users.php file, leading to an unrestricted file upload vulnerability. This vulnerability allows an unauthenticated remote attacker with low privileges to upload arbitrary files to the server without restrictions. The CVSS 4.0 vector indicates the attack can be performed remotely (AV:N) with low attack complexity (AC:L), no authentication required (AT:N), and no user interaction (UI:N). The impact on confidentiality, integrity, and availability is low to limited (VC:L, VI:L, VA:L), suggesting that while exploitation is possible, the scope of damage may be constrained by other factors such as application logic or environment. No patches or mitigations have been published yet, and no known exploits are currently observed in the wild, although a public exploit has been released. The vulnerability could enable attackers to upload malicious scripts or web shells, potentially leading to remote code execution, data leakage, or further compromise of the e-commerce platform and its underlying infrastructure. Given the administrative context of the vulnerable script, exploitation could allow attackers to escalate privileges or manipulate user accounts if combined with other vulnerabilities or misconfigurations.

For European organizations using the itsourcecode E-Commerce Website 1.0 platform, this vulnerability poses a significant risk to the security and integrity of their online commerce operations. Successful exploitation could lead to unauthorized access to sensitive customer data, including personal and payment information, resulting in data breaches and regulatory non-compliance under GDPR. Additionally, attackers could deploy malware or ransomware, disrupt service availability, or deface websites, damaging brand reputation and customer trust. The unrestricted upload capability could also serve as a foothold for lateral movement within corporate networks. Given the e-commerce sector's critical role in European economies and the strict data protection regulations, the impact extends beyond technical compromise to legal and financial consequences. Organizations relying on this platform must consider the potential for financial fraud, loss of customer confidence, and operational downtime.

Immediate mitigation steps include restricting access to the /admin/users.php endpoint to trusted administrators only, ideally through network segmentation or VPN access. Implementing strict server-side validation and filtering of uploaded files is critical to prevent malicious payloads. Employing web application firewalls (WAFs) with custom rules to detect and block suspicious upload attempts can provide an additional layer of defense. Organizations should monitor logs for unusual file upload activities and conduct regular security audits of their e-commerce platforms. Until an official patch is released, consider disabling or restricting the upload functionality if feasible. Applying the principle of least privilege to user accounts and ensuring that the web server runs with minimal permissions can limit the impact of a successful exploit. Finally, organizations should prepare incident response plans tailored to web application compromises and maintain up-to-date backups to facilitate recovery.
