Welcome to our detailed analysis of CVE-2024-21144, a recently disclosed security vulnerability affecting versions of Oracle Java SE and Oracle GraalVM Enterprise Edition. This guide aims to provide you with clear and valuable insights into what the vulnerability entails, the specific software versions impacted, and the steps you can take to safeguard your systems.
CVE-2024-21144 refers to a security flaw in the concurrency component of Oracle Java SE and Oracle GraalVM Enterprise Edition. This vulnerability is present in various versions, namely Oracle Java SE: 8u411, 8u411-perf, 11.0.23; and Oracle GraalVM Enterprise Edition: 20.3.14 and 21.3.10.
Although classified with a low severity score of 3.7 by the Common Vulnerability Scoring System (CVSS), the security issue allows an unauthenticated attacker with network access through multiple protocols to partially disrupt service. Such disruptions can lead to a partial denial of service (DOS), albeit the exploitation of this vulnerability is considered challenging.
The vulnerability principally affects Java applications running in a client-side, sandboxed environment, such as Java Web Start applications and Java applets. These applications typically load and execute untrusted code from the internet and rely deeply on the Java security sandbox for protection. Importantly, this vulnerability does not impact Java deployments on servers where only trusted code is executed—code typically installed by administrators.
A successful exploit of this vulnerability could allow an attacker to cause a partial DOS, thereby impacting the availability of the application but not the confidentiality or integrity of the data it processes.
In response to the identification of CVE-2024-21144, Oracle has released patches for the affected versions. It's crucial for organizations and individuals using the impacted versions of Oracle Java SE and Oracle GraalVM Enterprise Edition to apply these patches to mitigate the risk of exploitation. Proactive security maintenance, including regular updates and patches, is essential in protecting your digital assets from potential threats.
