CVE-2021-45348Public exploitNetwork attack vector

Service crash via arbitrary CSV file deletion

Published Feb 14, 2022 · Updated Aug 4, 2024

Arbitrary file deletion in SourceCodester Attendance Management System 1.0 allows remote attackers to crash the service via a crafted csv parameter. In admin/pageUploadCSV.php, get_csv accepts an attacker-selected readable basename, and delete_csv passes the resulting CSV-directory path directly to unlink. The vulnerable web action requires no authentication or user interaction, and its documented consequence is deletion of a selected CSV file and service interruption.
