The vulnerability CVE-2025-14638 affects the itsourcecode Online Pet Shop Management System version 1.0, specifically in the /pet1/update_cnp.php endpoint. The issue arises from improper handling of the 'ID' parameter, which is susceptible to SQL injection attacks. This means an attacker can craft malicious input to manipulate backend SQL queries, potentially extracting sensitive data, modifying records, or causing denial of service by corrupting the database. The vulnerability can be exploited remotely without any authentication or user interaction, increasing the attack surface. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P) indicates network attack vector, low attack complexity, no privileges or user interaction required, and partial impacts on confidentiality, integrity, and availability. Although no exploits are currently known in the wild, the public disclosure of the vulnerability details raises the risk of exploitation by opportunistic attackers. The lack of available patches or vendor advisories means organizations must implement their own mitigations. The vulnerability is typical of classic SQL injection flaws caused by insufficient input validation and lack of parameterized queries or prepared statements in the affected PHP script.

For European organizations using the itsourcecode Online Pet Shop Management System 1.0, this vulnerability poses a risk of unauthorized data access, data manipulation, and potential service disruption. Pet shop management systems often store sensitive customer data, inventory details, and transaction records, so exploitation could lead to data breaches affecting customer privacy and business operations. Attackers could extract confidential information, alter pricing or inventory data, or disrupt order processing, damaging business reputation and causing financial losses. Given the remote and unauthenticated nature of the exploit, attackers can target vulnerable systems at scale. This is particularly concerning for small to medium enterprises in Europe that may lack dedicated cybersecurity resources. The absence of known exploits currently limits immediate impact, but the public disclosure increases the likelihood of future attacks. Compliance with GDPR and other data protection regulations means that affected organizations could face legal and regulatory consequences if breaches occur.

Organizations should immediately audit their deployment of the itsourcecode Online Pet Shop Management System version 1.0 to identify if the vulnerable /pet1/update_cnp.php script is in use. Since no official patches are available, the primary mitigation is to implement robust input validation and sanitization on the 'ID' parameter. Refactoring the code to use parameterized SQL queries or prepared statements is critical to prevent injection. Web application firewalls (WAFs) can be deployed to detect and block SQL injection attempts targeting this endpoint. Network segmentation and restricting external access to the management system can reduce exposure. Regularly monitoring logs for suspicious SQL queries or unusual activity related to the vulnerable script is advised. Organizations should also consider upgrading to a newer, secure version of the software if available or migrating to alternative solutions with better security track records. Finally, staff training on secure coding and vulnerability management will help prevent similar issues.
