An Indian researcher, Prakhar Prasad found a Blind SQL Injection vulnerability in the Paypal Notifications (https://www.paypal-notify.com) application as part of a bug bounty program. The bug enabled him to access the Paypal Notifications system database. The Paypal team patched the vulnerability immediately due to the severity of the issue. The Register reports that the flaw was found in the module that sends an email confirming the email address of the account holder. Ultimately, this vulnerability could have enabled attackers to steal sensitive information from PayPal’s databases.

The blind SQL injection vulnerability that was detected existed in the official PayPal e-commerce website application, specifically in the email confirmation module. The vulnerability allowed remote attackers or a local low-privileged application user account to inject or execute (blind) SQL commands on the affected application databases.
There are frequent research reports in the news showing that SQL Injection remains one of the most prevalent vulnerabilities exploited by hackers. In at least one report, SQL Injection was tied for first place with DDOS attacks.
