CVE-2024-31880: IBM Db2 Denial of Service Vulnerability: Know the Risks and Protect Your Data!

Overview

A recently discovered security vulnerability (CVE-2024-31880) in IBM Db2 for Linux, UNIX, and Windows (including Db2 Connect Server) versions 10.5, 11.1, and 11.5 has been found to leave the server susceptible to a denial of service (DoS) attack under specific configurations. This can result in the disruption of normal services, causing huge consequences for businesses and users alike. The risk stems from a crafted SQL statement, which can cause the server to crash when executed by an authenticated user. The following is a deep dive into the details of this vulnerability, including the exploit details, a code snippet, and links to original references.

Exploit Details

The core issue lies in the way Db2 handles certain SQL statements. When a specific type of SQL statement is executed in the vulnerable environment, the Db2 server crashes, leading to a DoS attack. In order to exploit this vulnerability, an attacker must have authenticated access to the Db2 server. Once authenticated, the attacker can craft the SQL statement, targeting the weak configuration, and execute it to cause the server to crash, disrupting the services it provides.

Code Snippet

Here is an example of a code snippet showcasing a crafted SQL statement that could exploit this vulnerability:

SELECT * FROM vulnerable_table WHERE crafted_attack_payload(COLUMN_NAME, exploit_configurations);

Note: This is just an example and does not represent an actual exploit code. Actual exploit code should not be shared to avoid malicious use.
