CVE-2008-5353 is a critical vulnerability in Sun JDK/JRE (6u10 and earlier, 5.0u16 and earlier, 1.4.2_18 and earlier) and other Java implementations (OpenJDK, GIJ, icedtea) that allows remote attackers to bypass the Java security sandbox and execute arbitrary code. The flaw is due to improper enforcement of context during deserialization of sun.util.calendar.ZoneInfo objects in java.util.Calendar, allowing attacker-controlled input to be deserialized in a privileged context. This enables untrusted Java applets or applications to gain full privileges of the user running the browser, leading to remote code execution. The exploit is reliable, platform-independent, and does not require memory corruption, making it highly weaponizable.

This repository contains a single Metasploit module: 'java_calendar_deserialize.rb', which exploits CVE-2008-5353, a deserialization vulnerability in Sun Java's Calendar objects. The exploit is delivered via a malicious HTTP server that serves a crafted Java applet (CVE-2008-5353.jar) to the victim's browser. When a vulnerable Java version is present and the user visits the attacker's server, the applet triggers the vulnerability, allowing the attacker to execute arbitrary code on the target system. The module supports multiple payloads, including Java-based reverse shells and native executables for Windows, Linux, and Mac OS X. The exploit is highly weaponized, leveraging Metasploit's payload generation and HTTP server capabilities. The only fingerprintable endpoints are the malicious JAR file and the HTTP path used to deliver the applet. The repository is structured as a typical Metasploit exploit module, with all logic contained in a single Ruby file.
