CVE-2023-27250Public exploitNetwork attack vector

Database disclosure via injectable pubid parameter

Published Mar 16, 2023 · Updated Feb 26, 2025

SQL injection in Online Book Store Project 1.0 allows remote attackers to read database data through bookPerPub.php's pubid parameter. The script incorporates the supplied pubid value into its book-selection SQL without neutralizing SQL syntax, letting an EXTRACTVALUE expression return the active database name in an error. No authentication or user interaction is required; the published proof of concept demonstrates database-name disclosure but not database modification or code execution.
