AnalysisAIv1 – Jul 27, 2026

SQL injection in EasyAppointments <=1.5.1 allows unauthenticated attackers to extract and modify database contents via the order_by parameter of /customers/search. Under certain MySQL configurations, the flaw can escalate to remote code execution by writing a PHP webshell using INTO OUTFILE. Public exploit code exists, though no active exploitation has been reported to CISA KEV.

DescriptionCVE.org

SQL injection vulnerability exists in the order_by parameter of the /customers/search endpoint in Alex Tselegidis EasyAppointments <= 1.5.1. The vulnerability arises from unsanitized user input passed to the order_by method of the CodeIgniter Query Builder, enabling attackers to perform time-based queries and schema enumeration. Under certain MySQL configurations, the flaw may lead to remote code execution by writing a PHP shell using INTO OUTFILE.

Attack Technique

SQL injection exploits the way applications construct database queries by mixing user input directly into SQL statements.

Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
