CVE-2025-9702 is a SQL Injection vulnerability identified in version 1.0 of the SourceCodester Simple Cafe Billing System, specifically within the /sales_report.php file. The vulnerability arises from improper sanitization or validation of the 'month' parameter, which is used in SQL queries. An attacker can manipulate this parameter remotely without any authentication or user interaction to inject malicious SQL code. This can lead to unauthorized access to the underlying database, allowing attackers to read, modify, or delete sensitive data related to sales reports or other business-critical information stored in the database. The vulnerability has a CVSS 4.0 base score of 6.9, indicating a medium severity level. The attack vector is network-based (AV:N), requires no privileges (PR:N), no user interaction (UI:N), and no authentication (AT:N), making exploitation relatively straightforward if the system is exposed. The impact on confidentiality, integrity, and availability is limited but present (VC:L, VI:L, VA:L), meaning attackers can partially compromise these security properties. No patches or fixes have been linked yet, and while no known exploits are reported in the wild, a public exploit is available, increasing the risk of exploitation. The vulnerability affects only version 1.0 of the product, which is a niche billing system likely used by small to medium-sized cafes or similar businesses for sales and billing management.

For European organizations using the Simple Cafe Billing System 1.0, this vulnerability poses a risk of unauthorized database access, potentially exposing sensitive sales data, customer information, and financial records. While the product is specialized and likely not widespread among large enterprises, small and medium-sized businesses in the hospitality sector could be targeted. Exploitation could lead to data breaches, financial fraud, or manipulation of sales records, impacting business operations and customer trust. Additionally, compromised systems could be leveraged as footholds for further attacks within the network. Given the lack of authentication and user interaction requirements, attackers can exploit this vulnerability remotely, increasing the risk for organizations with internet-facing deployments. The medium severity rating suggests that while the threat is significant, it may not lead to full system compromise or widespread disruption without additional vulnerabilities or misconfigurations.

Organizations should immediately audit their use of the Simple Cafe Billing System, especially version 1.0, and restrict access to the /sales_report.php endpoint to trusted internal networks only. Implementing web application firewalls (WAFs) with specific rules to detect and block SQL injection patterns targeting the 'month' parameter can provide a temporary defense. Developers or administrators should review and sanitize all user inputs rigorously, employing parameterized queries or prepared statements to prevent SQL injection. Since no official patches are currently available, consider isolating the affected system from public networks or replacing it with updated or alternative billing software that follows secure coding practices. Regularly monitoring logs for suspicious query patterns and anomalous database access can help detect exploitation attempts early. Finally, organizations should maintain backups of critical data to enable recovery in case of data tampering or loss.
