CVE-2026-11485

An attacker can remotely exploit this vulnerability by sending a crafted POST request to the '/archive2.php' file. The 'sy' parameter is vulnerable to SQL injection, allowing attackers to inject malicious SQL code. This can be used to manipulate database queries, leading to unauthorized data access or modification. No login or authorization is required to exploit this vulnerability [ref_id=1].

The vulnerability resides in the '/archive2.php' file of the Class and Exam Timetabling System version 1.0. Specifically, the 'sy' parameter is directly incorporated into SQL queries without adequate cleaning or validation, as detailed in the vulnerability description [ref_id=1].

The advisory suggests using prepared statements and parameter binding to prevent SQL injection, as this method treats user input as data rather than executable SQL code. Additionally, it recommends strict input validation and filtering to ensure user data conforms to expected formats. Minimizing database user permissions and conducting regular security audits are also advised remediation steps [ref_id=1]. The patch does not show specific code changes, but these measures would prevent the 'sy' parameter from being interpreted as SQL.
