IBM Sterling B2B Integrator versions 6... through 6.1.2.5 and 6.2.. through 6.2..1 have been found to be vulnerable to a SQL injection attack. This critical vulnerability could allow a remote attacker to gain unauthorized access to sensitive information as well as add, modify, or delete data in the back-end database by sending specially crafted SQL statements. In this post, we will discuss the details of this CVE-2023-50316 vulnerability and provide code snippets to assist in understanding the nature of the attack.

Vulnerability Details

SQL injection is a well-known security issue that occurs when an attacker injects malicious SQL code into user input fields, such as a search bar, online forms, or URL parameters. The attacker could then exploit the vulnerability to manipulate the underlying database, leading to potential data breaches.

For CVE-2023-50316, an attacker could take advantage of inadequately validated user input in IBM Sterling B2B Integrator and inject malicious SQL code that compromises the security and integrity of the back-end database.

As a result, the attacker may be able to exfiltrate sensitive data, insert fraudulent information, alter existing records, or even delete critical data from the database, which can lead to severe financial and reputation damages for organizations relying on IBM Sterling B2B Integrator.

Code Snippet Example

The code snippet below demonstrates a simple, yet effective SQL injection payload that an attacker might use to exploit CVE-2023-50316:

search_param = "'; DROP TABLE users; --"

sql_query = "SELECT * FROM contacts WHERE name LIKE '%" + search_param + "%';"

In this example, a seemingly harmless search parameter is injected with malicious SQL code that, if executed, will drop the entire "users" table from the database. Once the SQL statement is executed, the attacker would successfully delete crucial user data.
