What to do

AI-suggested

Since the vulnerability arises from a publicly accessible backup file, immediate mitigation involves removing or restricting access to the /obs/database/obs_db.sql file on the web server. Access controls should be applied to prevent unauthenticated HTTP requests from retrieving sensitive backup files. Monitor vendor advisories for any forthcoming patches or official remediation.

Description

An information disclosure vulnerability exists in the SourceCodester Simple Online Book Store System due to a web-accessible backup file. A remote unauthenticated attacker can retrieve the full database contents, including schema and credential hashes, via an HTTP GET request to /obs/database/obs_db.sql. This vulnerability allows unauthorized access to sensitive data without requiring authentication.
