Product | Affected Versions
Oracle Java SE | 8u451, 8u451-perf, 11.0.27, 17.0.15, 21.0.7, 24.0.1
Oracle GraalVM for JDK | 17.0.15, 21.0.7, 24.0.1
Oracle GraalVM Enterprise Edition | 21.3.14
How the Exploit Works
The exploit takes advantage of a vulnerability in the 2D component of the Oracle Java SE, Oracle GraalVM for JDK, and Oracle GraalVM Enterprise Edition. The vulnerability can be exploited remotely by a network attacker without any need for authentication. This is achieved by using APIs in the specified Component, possibly through a web service that supplies data to the APIs. This vulnerability is especially dangerous in Java deployments, where untrusted code (e.g., code from the internet) is loaded and run, and security is dependent on the Java sandbox.
Conceptual Example Code
While the exact code to exploit this vulnerability is beyond the scope of this article, the following is a conceptual example of how a malicious payload might be delivered through a web service.
POST /api/2DComponent HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "malicious_data": "..." }In this example, a HTTP POST request is made to a vulnerable endpoint on the target system. A malicious payload is included in the body of the request, masked as legitimate data. The target system, not recognizing the danger, accepts and processes the payload, leading to a potential system compromise or data leakage.
Mitigation Guidance
To prevent exploitation of this vulnerability, it is recommended that affected systems apply the vendor patch as soon as possible. If the patch cannot be applied immediately, implementing a temporary mitigation strategy such as a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can help protect the system until the patch can be applied.
