Unpatched SQL injection vulnerabilities found by Rapid7 researchers in the SmartVista e-payments suite from Switzerland-based BPC Banking Technologies can expose sensitive information.
The SmartVista platform is used by major organizations around the world for online banking, e-commerce, ATM and card management, and fraud prevention. The core components of the SmartVista suite are the Front-End and Back-Office systems.
Researchers at Rapid7 discovered that the SmartVista Front-End, specifically version 2.2.10 revision 287921, is affected by two SQL injection vulnerabilities.
According to the security firm, an attacker who has access to the SmartVista Front-End interface can exploit the flaws to obtain data stored in the backend database.
The “Transactions” page in the “Customer Service” section of SmartVista Front-End allows users to view transaction details associated with a specified card or account. However, the fields where the card and account number are entered fail to sanitize user-supplied input.
This allows a malicious actor to use specially crafted queries to get the application to display data from the backend database, including usernames, passwords, card numbers, and other transaction details.
Rapid7 researchers demonstrated that entering a Boolean search term such as ‘ or ‘1’=’1, in the “Account Number” field resulted in all transactions being displayed. While there is a 5 second delay when a similar Boolean search term is entered into the “Card Number” field, a time-based SQL injection attack is still possible.
Rapid7 reported its findings to BPC on May 10, but a patch has yet to be released. CERT/CC and SwissCERT have also tried contacting the vendor, but without any success. The security firm gives vendors at least 60 days before publicly disclosing vulnerabilities found in their products.
SecurityWeek has reached out to BPC for comment and will update this article if the company responds.
“Users should contact BPC support for more details. In the meantime, access to the management interface of SmartVista should be as limited as possible, and audits of successful and failed logins should be performed regularly. A web application firewall (WAF) can help mitigate, or at least complicate, exploitation that relies on common SQL injection techniques,” Rapid7 advised users.
