The CodeAstro Payroll System 1.0 contains an SQL injection vulnerability in the /home_employee.php file. The vulnerability arises from improper sanitization of the emp_id parameter, allowing remote attackers to inject SQL commands. This can potentially lead to unauthorized data access or modification. The vulnerability is rated medium severity with a CVSS 4.0 score of 5.3. No official remediation or patch has been published by the vendor as of the current information. Public exploit code exists, increasing the risk of exploitation.

Successful exploitation of this SQL injection vulnerability could allow an attacker with low privileges to execute arbitrary SQL commands on the backend database. This may lead to unauthorized disclosure, modification, or deletion of payroll data. However, the overall impact is limited by the vulnerability's vector and conditions, reflected in the medium severity rating. There are no confirmed reports of active exploitation in the wild at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, it is recommended to restrict access to the affected application, apply web application firewall (WAF) rules to detect and block SQL injection attempts targeting the emp_id parameter, and review application logs for suspicious activity related to this vulnerability. Avoid exposing the affected endpoint to untrusted networks if possible.
