Blind SQL Injection in Oracle Database: Exfiltrating Data with Burp Collaborator — SQL Injection…
1 min read
Summary
The lab in question revolves around a blind SQL injection vulnerability in an application that uses a tracking cookie for analytics, with the cookie value embedded in a SQL query that is executed asynchronously.
By exploiting this vulnerability, it is possible to trigger out-of-band interactions with an external domain for the purpose of extracting sensitive data.
In order to retrieve the administrator’s password from the database, which contains a table with usernames and passwords, SQL injection payloads can be employed, with the goal of logging in as the administrator.
Ethical hackers must ensure that they only use these techniques in controlled environments, such as PortSwigger Labs, for educational and training purposes, and never outside these approved environments.
The vulnerabilities could lead to data breaches, database information leaks, and further exploitation opportunities.
It is vital to mitigate these vulnerabilities through the use of parameterised queries or prepared statements.
