CVE-2017-20255Public exploitNetwork attack vector

Database reads and writes via visatype SQL injection

Published Jun 19, 2026 · Updated Jun 19, 2026

SQL injection in Joombooking JB Visa 1.0 allows remote attackers to read or alter database data through the visatype query parameter. The popup view reached through index.php with option=com_bookpro and view=popup processes attacker-controlled visatype input as executable SQL rather than neutralizing SQL syntax. No authentication or user interaction is required; a crafted GET request can expose credentials and table contents and modify database records.
