Loading vulnerability…
CVE-2015-8660 is a vulnerability in the ovl_setattr function in fs/overlayfs/inode.c in the Linux kernel through version 4.3.3. The vulnerability arises because ovl_setattr attempts to merge distinct setattr operations, which can allow local users to bypass intended access restrictions. By exploiting this flaw, a local attacker can modify the attributes of arbitrary overlay files via a specially crafted application.

This repository contains a single Metasploit module (Ruby file) for local privilege escalation on Linux systems via OverlayFS vulnerabilities (CVE-2015-1328 and CVE-2015-8660). The module targets specific kernel versions on Ubuntu, Fedora, and Red Hat, and is designed to be run from an existing shell or Meterpreter session. It checks the target's kernel version and distribution, prepares and uploads exploit binaries and payloads to writable directories (typically /tmp), and executes them to escalate privileges to root. The default payload is a reverse shell, but any compatible Metasploit payload can be used. The module is weaponized, allowing for easy payload customization and integration into the Metasploit framework. Key fingerprintable endpoints include temporary directories and payload file paths used during exploitation.
