CVE-2025-10431 is a SQL Injection vulnerability identified in SourceCodester Pet Grooming Management Software version 1.0. The vulnerability exists in the /admin/ajax_represent.php file, specifically involving the manipulation of the 'ID' argument. An attacker can exploit this flaw by injecting malicious SQL code through the 'ID' parameter, which is not properly sanitized or validated. This allows the attacker to interfere with the backend database queries, potentially leading to unauthorized data access, data modification, or even deletion. The vulnerability can be exploited remotely without requiring user interaction or authentication, increasing its risk profile. The CVSS 4.0 base score is 5.3 (medium severity), reflecting that while the attack vector is network-based and requires low attack complexity, it does require some privileges (PR:L) and results in limited confidentiality, integrity, and availability impacts. The vulnerability has been publicly disclosed, but there are no known exploits actively used in the wild at this time. No official patches have been linked yet, which means affected users must rely on other mitigation strategies until a fix is available.

For European organizations using SourceCodester Pet Grooming Management Software 1.0, this vulnerability poses a moderate risk. Exploitation could lead to unauthorized access to sensitive customer data, including personal and payment information, which is critical under GDPR regulations. Data integrity could be compromised, affecting business operations and trust. Availability impacts, though limited, could disrupt administrative functions. Given the software’s niche use in pet grooming businesses, the scale of impact may be limited to small and medium enterprises in this sector. However, any data breach involving personal data can lead to significant regulatory penalties and reputational damage in Europe. The remote exploitation capability without user interaction increases the urgency for mitigation, especially in environments where the software is exposed to the internet or untrusted networks.

Since no official patch is currently available, European organizations should implement immediate compensating controls. These include restricting network access to the administrative interface by IP whitelisting or VPN-only access, thereby reducing exposure to remote attackers. Input validation and sanitization can be enforced at the web server or application firewall level using Web Application Firewalls (WAFs) configured to detect and block SQL injection patterns targeting the 'ID' parameter. Regularly monitoring logs for suspicious queries or repeated failed attempts can help detect exploitation attempts early. Organizations should also plan to upgrade or patch the software promptly once a vendor fix is released. Additionally, conducting a thorough audit of database permissions to ensure the application uses least privilege principles can limit the damage if exploitation occurs. Backups of critical data should be maintained to enable recovery from potential data integrity attacks.
