Executive brief
The itsourcecode Courier Management System, a web application used for tracking and managing logistics, contains a security flaw in its parcel listing component.

This could lead to the theft of sensitive customer information, tampering with delivery records, or disruption of the management service.
Technical details
A SQL injection vulnerability exists in itsourcecode Courier Management System 1.0 within the '/parcel_list.php' file. The root cause is the improper neutralization of special elements in the 's' GET parameter, which is used in database queries without sufficient sanitization or parameterization. An authenticated attacker can exploit this remotely by submitting crafted SQL queries (including time-based blind and UNION-based payloads). Successful exploitation allows for unauthorized database access, data exfiltration, and potential modification of database records. No official patch is currently documented; remediation should involve implementing prepared statements and input validation.
