CVE-2022-21247 is a vulnerability in the Core RDBMS component of Oracle Database Server, specifically impacting supported versions 12.2.0.1 and 19c. This vulnerability allows a high privileged attacker, possessing the Create Session and Execute Catalog Role privileges and having network access via Oracle Net, to compromise the Core RDBMS. The vulnerability is classified with a CVSS 3.1 Base Score of 2.7, indicating a low severity primarily due to its confidentiality impact.
Successful exploitation can result in unauthorized read access to a subset of Core RDBMS accessible data. Organizations that rely on these database versions should be aware of this risk and the potential for data exposure.
Given the nature of this vulnerability, organizations should prioritize patching immediately to prevent potential unauthorized data access. The urgency is heightened due to the easily exploitable nature of the vulnerability, which can be accessed over the network.
The last modification of this vulnerability was recorded on November 21, 2024, indicating ongoing attention and the need for organizations to stay informed about security updates and patches from Oracle.
Vulnerability Details
This vulnerability allows high privileged attackers to exploit the Core RDBMS of Oracle Database Server, affecting versions 12.2.0.1 and 19c. It has a CVSS 3.1 Base Score of 2.7, categorized as low severity. The potential impacts are primarily confidentiality-related, as attackers may gain unauthorized access to sensitive data.
Technical Analysis
The root cause of CVE-2022-21247 lies in the Core RDBMS component of the Oracle Database Server, where insufficient access controls allow high privileged users to exploit the system. The attack vector is network-based, requiring minimal complexity and high privileges to execute. There is no user interaction required for exploitation, which increases the risk for affected systems.
The confidentiality impact is classified as low, indicating that while data may be exposed, the potential for significant harm is limited compared to other vulnerabilities. There are no integrity or availability impacts associated with this vulnerability.
Risk & Impact Analysis
The risk to organizations includes the potential unauthorized access to sensitive data, which can lead to data breaches and compliance issues. The blast radius is somewhat contained due to the requirement of high privileges for exploitation. However, the low CVSS score does not diminish the need for organizations to address this vulnerability proactively.
With a low EPS score of 0.002, this vulnerability is not currently classified as a significant risk but should still be monitored closely. Organizations should address this vulnerability in their priority patch cycle to maintain security and compliance.
