CVE-2023-22049 is a vulnerability in the Oracle Java SE, Oracle GraalVM Enterprise Edition, and Oracle GraalVM for JDK products. This vulnerability allows unauthenticated attackers with network access via multiple protocols to compromise these systems. Supported affected versions include Oracle Java SE 8u371, 11.0.19, 17.0.7, and 20.0.1, as well as GraalVM Enterprise Edition 20.3.10, 21.3.6, and 22.3.2. This low-severity vulnerability (CVSS 3.1 Base Score 3.7) can lead to unauthorized updates, inserts, or deletes of accessible data.
Successful exploitation can occur through APIs in the specified component, which may be accessed through web services. The vulnerability also applies to Java deployments, often in environments running sandboxed Java Web Start applications or applets that load untrusted code. As such, organizations using these technologies should be aware of the potential risks and take action to mitigate exposure.
Risk to organizations includes unauthorized data access or modification, which could impact application integrity. It is crucial for organizations to prioritize patching and updating their systems to mitigate this vulnerability effectively.
Organizations should address this vulnerability in their priority patch cycle to maintain the security of their applications and data.
Vulnerability Details
CVE-2023-22049 is officially described as a vulnerability in the Oracle Java SE, Oracle GraalVM Enterprise Edition, and Oracle GraalVM for JDK product components. The CVSS score is 3.7, categorized as low severity, indicating that although the vulnerability is difficult to exploit, the impact could still be significant in terms of data integrity.
The affected products include various versions of Oracle Java SE and GraalVM, specifically versions 8u371, 11.0.19, 17.0.7, 20.0.1, and GraalVM Enterprise Edition versions 20.3.10, 21.3.6, and 22.3.2. The vulnerability was published on July 18, 2023, and is classified under the CWE category of NVD-CWE-noinfo.
Technical Analysis
The root cause of CVE-2023-22049 involves issues in the libraries of Oracle Java SE and GraalVM that permit unauthenticated access over the network. The attack complexity is considered high, implying that specific conditions must be met for successful exploitation, such as having access to vulnerable APIs.
No privileges are required to exploit this vulnerability, and user interaction is not necessary, making it easier for attackers to leverage the vulnerability if they manage to access the network. The impact on confidentiality is negligible, but integrity is rated as low, meaning successful exploitation could lead to unauthorized modifications of data.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2023-22049 primarily stems from its potential to allow unauthorized access to sensitive data. Organizations utilizing Oracle Java SE or GraalVM products in their applications should consider the implications of an attacker being able to manipulate data without authorization.
With a low CVSS score, the urgency of remediation may vary. However, given that exploitation is possible through multiple protocols and APIs, organizations should treat this vulnerability with due diligence. The potential blast radius could include all systems utilizing the affected versions, emphasizing the need for immediate action to patch and secure these vulnerabilities.
