CVE-2025-10081 is a medium-severity vulnerability affecting SourceCodester Pet Management System version 1.0. The flaw resides in the /admin/profile.php file, specifically in the handling of the 'website_image' argument. This vulnerability allows an attacker to perform an unrestricted file upload, meaning that the system does not properly validate or restrict the types or contents of files uploaded through this parameter. Because the vulnerability is remotely exploitable without user interaction and does not require authentication (as indicated by the CVSS vector AV:N/AC:L/AT:N/UI:N), an attacker can directly upload malicious files to the server. This could lead to arbitrary code execution, server compromise, or defacement if the uploaded files are executed or accessed. The CVSS score of 5.1 reflects a medium severity, with limited impact on confidentiality, integrity, and availability, but the ease of exploitation and remote attack vector increase the risk. Although no known exploits are currently observed in the wild, the exploit code has been published, increasing the likelihood of future attacks. The vulnerability's impact is limited to version 1.0 of the product, and no patches have been linked yet, indicating that affected organizations must take immediate mitigation steps to reduce risk.

For European organizations using SourceCodester Pet Management System 1.0, this vulnerability poses a tangible risk of unauthorized access and potential system compromise. Pet management systems often handle sensitive data such as client information, pet health records, and appointment scheduling, which could be exposed or manipulated. An attacker exploiting this vulnerability could upload web shells or malware, leading to data breaches, service disruption, or lateral movement within the network. This could result in reputational damage, regulatory penalties under GDPR for data exposure, and operational downtime. Given the remote exploitability without authentication, attackers could target exposed administrative interfaces directly. The medium severity suggests that while the impact is not catastrophic, the risk is significant enough to warrant prompt attention, especially in organizations where this system is integrated with other critical infrastructure or contains sensitive personal data.

Since no official patches are currently available, European organizations should implement immediate compensating controls. First, restrict access to the /admin/profile.php endpoint by IP whitelisting or VPN access to limit exposure to trusted users only. Implement web application firewall (WAF) rules to detect and block suspicious file uploads, especially those containing executable code or uncommon file types. Conduct thorough input validation and sanitization on the 'website_image' parameter if custom code modifications are possible. Monitor server logs for unusual upload activity or access patterns. Disable or restrict file execution permissions in the upload directory to prevent execution of malicious files. Additionally, organizations should plan to upgrade or patch the Pet Management System as soon as a vendor fix is released. Regular backups and incident response readiness will also help mitigate potential damage from exploitation.
