CVE-2013-2460 is an unspecified vulnerability in the Serviceability component of Oracle Java SE / JRE 7 Update 21 and earlier, also affecting OpenJDK 7. Oracle’s June 2013 CPU states that the issue allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors related to Serviceability. Supporting content further notes third-party reporting that associated the flaw with insufficient access checks in the Java tracing component, enabling a Java sandbox bypass. The content also references exploitation as a client-side Java issue in exploit kits and tooling, including descriptions such as "Oracle Java ProviderSkeleton invoke() remote code execution," but the precise vulnerable function and root-cause details are not fully specified in the provided material.

This repository contains a single Metasploit module: 'java_jre17_provider_skeleton.rb', which exploits CVE-2013-2460, a vulnerability in Oracle Java (version 7u21 and earlier). The exploit abuses the insecure invoke() method of the ProviderSkeleton class, allowing arbitrary static method calls with user-supplied arguments. The module sets up a malicious HTTP server that serves a crafted Java applet (delivered as a .jar file) to the victim's browser. When the victim visits the attacker's page, the applet is executed, exploiting the vulnerability to run arbitrary code on the client system. The module supports multiple payloads (Java, Windows, Linux, OSX) and can deliver any Metasploit-supported payload. The exploit is weaponized, as it is part of the Metasploit framework and allows for easy payload customization. The main endpoints are the malicious .class files loaded from the Metasploit data directory. The attack vector is browser-based, requiring user interaction (visiting a malicious page) and a vulnerable Java plugin. The repository is structured as a single Ruby file implementing the Metasploit exploit module.
