Executive brief
The Simple Online Book Store System, a web application for managing book sales, contains a security flaw where a database backup file is publicly accessible. An unauthorized person can download this file over the internet without needing a password. This allows them to view the entire database, including sensitive information like user account details and password hashes, which could lead to full account takeovers.
Technical details
An information disclosure vulnerability exists in SourceCodester Simple Online Book Store System 1.0 due to improper access control on sensitive files. The application stores a full SQL database backup in a predictable, web-accessible directory (/obs/database/obs_db.sql) without requiring authentication. A remote attacker can exploit this by sending a simple HTTP GET request to the file path. Successful exploitation grants the attacker access to the entire database schema, administrative credentials (in hashed format), and other stored sensitive data. As of the advisory date, there is no mention of a formal patch; administrators should restrict access to the /database directory or remove the SQL file from the web root.
