CVE-2024-21007 is a high-severity vulnerability affecting the Oracle WebLogic Server component of Oracle Fusion Middleware. It has been assigned a CVSS score of 7.5, indicating significant risk to organizations. This vulnerability allows unauthenticated attackers with network access via T3 and IIOP protocols to compromise Oracle WebLogic Server, leading to unauthorized access to critical data or complete access to all accessible data.
The urgency for organizations to address this vulnerability is high. Successful exploitation can have severe consequences, including data breaches that may affect sensitive information. Given the nature of the vulnerability, it is easily exploitable, necessitating immediate action from security teams.
As of now, there is no known public exploit or proof of concept available for this vulnerability, but organizations should not rely on this status. The vulnerability has been analyzed and officially disclosed, and it is crucial for organizations to prioritize patching immediately.
Given the potential impact and exploitability, organizations using affected versions of Oracle WebLogic Server should take proactive measures to secure their systems.
Vulnerability Details
This vulnerability allows unauthenticated attackers with network access to compromise the Oracle WebLogic Server. Supported affected versions are 12.2.1.4.0 and 14.1.1.0.0. The CVSS 3.1 Base Score of 7.5 indicates high confidentiality impact. The CVSS Vector is (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), which reflects the low attack complexity and the lack of required privileges or user interaction.
The vulnerability is classified under CWE-306, which refers to missing authentication for critical functions. The official disclosure was made on April 16, 2024, and organizations should consult the advisory for detailed remediation steps.
Technical Analysis
The root cause of CVE-2024-21007 lies in the lack of authentication for certain functions within the Oracle WebLogic Server. Attackers can exploit this vulnerability through the network, utilizing T3 and IIOP protocols. The attack complexity is categorized as low, meaning an attacker does not need advanced skills to successfully exploit this vulnerability.
No privileges are required for exploitation, and user interaction is not necessary, further amplifying the risk. The vulnerability impacts confidentiality significantly, as attackers may gain access to sensitive data without detection. There are no integrity or availability impacts associated with this vulnerability.
Risk & Impact Analysis
Risk to organizations includes potential unauthorized access to critical data, which could lead to data breaches and reputational damage. The blast radius of this vulnerability is extensive, as it affects all instances of the affected WebLogic Server versions that are publicly accessible over the network.
Given the CVSS score of 7.5 and the analysis indicating high exploitability, organizations should address this vulnerability in their priority patch cycle. The lack of public exploit information does not mitigate the risk; the vulnerability's characteristics make it a feasible target for attackers.
