CVE-2023-22096 - Critical Vulnerability in Oracle Database Server's Java VM Component

CVE-2023-22096 is a significant vulnerability discovered in the Java Virtual Machine (Java VM) component of the Oracle Database Server. Affected server versions include 19.3-19.20 and 21.3-21.11. This security flaw allows low privileged attackers with Create Session, Create Procedure privileges and network access via Oracle Net to exploit and compromise the Java VM component. The vulnerability could lead to unauthorized updates, insertions, or deletions of accessible data within Java VM. Here's a detailed breakdown of the various aspects of the vulnerability, along with code snippets, links to original references, and details about exploitation.

* Original Reference: CVE-2023-22096
* CVSS 3.1 Base Score: 4.3 (Integrity impacts)
* CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N)

Exploit Details

Given the proper network access and privileges, an attacker can easily exploit this vulnerability to gain unauthorized access to data within the Java VM component. This is particularly concerning for organizations leveraging the highly vulnerable Oracle Database Server versions mentioned earlier in this post.

While the exact steps to exploit this vulnerability are not disclosed (to avoid misuse), understanding the nature of the vulnerability and how it can be manipulated by an attacker is critical for organizations and individuals looking to protect their systems.
