CVE-2025-10688 is a SQL Injection vulnerability identified in SourceCodester Pet Grooming Management Software version 1.0. The vulnerability resides in the /admin/operation/paid.php file, where manipulation of the parameters 'inv_no' or 'insta_amt' allows an attacker to inject malicious SQL code. This flaw enables remote attackers to execute unauthorized SQL commands on the backend database without requiring authentication or user interaction. The vulnerability is rated with a CVSS 4.0 base score of 6.9 (medium severity), reflecting its network attack vector, low complexity, and no privileges or user interaction needed. The impact on confidentiality, integrity, and availability is limited but present, as the vulnerability allows partial compromise of the database content. The exploit has been publicly disclosed, increasing the risk of exploitation, although no known active exploits in the wild have been reported yet. The lack of available patches or mitigations from the vendor further increases the urgency for affected users to implement compensating controls. This vulnerability is typical of improper input validation and insufficient parameter sanitization in web applications, leading to injection flaws that can be leveraged to extract sensitive data, modify records, or disrupt service.

For European organizations using SourceCodester Pet Grooming Management Software 1.0, this vulnerability poses a moderate risk. Pet grooming businesses and related service providers that rely on this software could face unauthorized data disclosure, including customer and payment information, potentially violating GDPR requirements. Data integrity could be compromised, leading to inaccurate billing or service records, which may disrupt business operations and damage reputation. Although the vulnerability does not require authentication, the scope is limited to organizations using this specific software version, which may not be widespread in Europe. However, any exploitation could lead to regulatory penalties and loss of customer trust. The public disclosure of the exploit code increases the likelihood of opportunistic attacks, especially from automated scanning and exploitation tools targeting vulnerable web applications.

Since no official patches are currently available, European organizations should immediately implement the following mitigations: 1) Restrict access to the /admin/operation/paid.php endpoint by IP whitelisting or VPN-only access to reduce exposure. 2) Employ Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting the 'inv_no' and 'insta_amt' parameters. 3) Conduct a thorough code review and apply input validation and parameterized queries or prepared statements to sanitize inputs in the affected file. 4) Monitor logs for suspicious activity related to SQL injection patterns and anomalous database queries. 5) Consider isolating or temporarily disabling the vulnerable functionality if feasible until a vendor patch is released. 6) Educate staff about the risk and ensure backups are up to date to enable recovery from potential data corruption or loss.
