CVE-2025-30751 is a high-severity vulnerability in the Oracle Database component of Oracle Database Server. With a CVSS score of 8.8, this vulnerability allows a low privileged attacker with the Create Session and Create Procedure privileges to exploit the database via network access. The impact of successful exploitation can lead to a complete takeover of the Oracle Database, significantly jeopardizing the confidentiality, integrity, and availability of data.
The vulnerability affects supported versions 19.27 and 23.4-23.8 of the Oracle Database. Given its ease of exploitation and potential consequences, organizations should prioritize patching immediately. This urgency is underscored by the CVSS scoring, which indicates that organizations face serious risks to their operational integrity and data security.
Currently, there are no known exploits or public proofs of concept available for this vulnerability. However, its high exploitability score indicates that attackers may actively seek to exploit this weakness in the wild, further emphasizing the need for swift remediation.
Organizations must remain vigilant and proactive in their security posture, especially concerning high-severity vulnerabilities like CVE-2025-30751. The potential risks associated with this vulnerability necessitate immediate action in patch management and security assessments.
Vulnerability Details
The vulnerability allows an attacker with low privileges to take control of the Oracle Database server due to insufficient access controls. The CVSS 3.1 Base Score is 8.8, indicating high severity, with the following metrics: Attack Vector (Network), Attack Complexity (Low), Privileges Required (Low), User Interaction (None), and Confidentiality, Integrity, and Availability impacts rated as High.
Affected versions include Oracle Database Server version 19.27 (from 19.3 to 19.27) and versions 23.4 to 23.8. The CWE classification for this vulnerability is CWE-863, indicating improper authorization.
Technical Analysis
The root cause of CVE-2025-30751 stems from inadequate access controls within the Oracle Database system. The attack vector is network-based, allowing attackers to exploit the vulnerability remotely. The attack complexity is classified as low, meaning that the likelihood of successful exploitation is high for attackers with the necessary privileges.
Privileges required for successful exploitation are low, as attackers need only the Create Session and Create Procedure privileges. There is no user interaction needed, making it easier for the attacker to execute their attack without detection.
The potential impacts of exploitation include significant confidentiality, integrity, and availability concerns. Successful attacks could lead to unauthorized access to sensitive data, data manipulation, and disruption of database services.
Risk & Impact Analysis
The risk associated with CVE-2025-30751 is substantial due to the potential for database takeover. Organizations relying on Oracle Database Server for critical operations must recognize the serious implications of this vulnerability, as it could lead to data breaches and operational disruptions.
Given the high CVSS score and the nature of the vulnerability, organizations should prioritize remediation in their patch management process. With the potential for widespread impacts, timely updates and security assessments are crucial to maintaining the integrity and security of database systems.
Organizations should also consider the blast radius of this vulnerability. If exploited, the attacker could gain access to sensitive information across various applications and services that rely on the compromised database, potentially leading to further attacks within the organization's infrastructure.

Affected Versions
The affected versions of the Oracle Database Server include 19.27 (from 19.3 to 19.27) and versions 23.4 to 23.8. Organizations using these versions must take immediate action to mitigate the risks posed by this vulnerability.
Mitigation & Remediation
Oracle has provided a patch to remediate this vulnerability. Organizations should consult the Oracle Critical Patch Update Advisory for July 2025 for specific patch details and instructions on implementation.
In addition to applying patches, organizations should ensure that their database configurations are hardened and that they have robust network controls in place to minimize exposure to potential threats. Regular monitoring and security assessments are also recommended to detect any anomalous behaviors.
Penetration testing can also be beneficial in identifying weaknesses that may not be addressed by standard patching.
Detection Guidance
Organizations should monitor logs for unusual access patterns, particularly attempts to create sessions or procedures from unrecognized sources. Behavioral anomalies within the database environment should be flagged for further investigation.
Network signatures that indicate unauthorized access attempts or unusual traffic patterns should be implemented to detect potential exploitation attempts.
AppSecure Threat Intelligence Insight
