CVE-2026-5180: SQL Injection in Simple Doctors Appointment System

The SQL Injection vulnerability in Simple Doctors Appointment System poses a significant risk. An attacker could leverage this flaw to bypass authentication mechanisms and gain unauthorized access to the application's database. This could lead to the exfiltration of sensitive patient data, appointment schedules, and administrative credentials. Furthermore, the attacker might be able to modify or delete data, disrupt system operations, or even execute arbitrary commands on the underlying server, depending on database permissions. The published exploit increases the likelihood of immediate exploitation.

The primary mitigation for CVE-2026-5180 is to upgrade to a patched version of Simple Doctors Appointment System. Since a fixed version is not specified, immediate action is crucial. As a temporary workaround, implement Web Application Firewall (WAF) rules to filter potentially malicious SQL injection attempts targeting the /admin/ajax.php?action=login2 endpoint. Additionally, strengthen input validation routines to sanitize user-supplied data, particularly the 'email' parameter, before it is used in database queries. Regularly review database user permissions to limit the potential impact of a successful attack. After implementing these measures, verify their effectiveness by attempting controlled SQL injection tests.
