CVE-2015-0311 is an unspecified remote code execution vulnerability in Adobe Flash Player affecting Windows, OS X, and Linux. Affected versions include Flash Player through 13.0.0.262 and 14.x, 15.x, and 16.x through 16.0.0.287 on Windows and OS X, and through 11.2.202.438 on Linux. The flaw was exploited in the wild as a zero-day in early 2015 and was rapidly incorporated into multiple exploit kits, including Angler, Sundown, RIG, Fiesta, Nuclear Pack, Sweet Orange, Neutrino, and Magnitude. Observed exploitation commonly occurred through malvertising or exploit-kit landing pages that delivered a malicious Flash object to vulnerable browsers, resulting in arbitrary code execution and subsequent malware installation such as Bedep and TeslaCrypt. Specific vulnerable functions or root-cause details are not available from the provided information.

This repository contains a single Metasploit module that exploits a use-after-free vulnerability (CVE-2015-0311) in Adobe Flash Player's ByteArray::UncompressViaZlibVariant method. The exploit targets vulnerable versions of Flash Player on both Windows and Linux platforms, specifically when used in Internet Explorer or Firefox browsers. The module sets up a browser exploit server that delivers a malicious SWF file to the victim. When the victim visits the attacker's web page, the SWF file is served and triggers the vulnerability, allowing the attacker to execute arbitrary code in the context of the browser. The exploit is highly weaponized, leveraging Metasploit's payload system to deliver a variety of post-exploitation payloads. The only fingerprintable network endpoint is the reference to the official Macromedia Flash ActiveX control, and the main file endpoint is the malicious SWF file used in the attack. The module is well-structured, with clear targeting and payload delivery mechanisms, and is suitable for use in penetration testing or red team engagements targeting legacy systems with outdated Flash installations.
