CVE-2015-1318 is a privilege escalation vulnerability in Apport (versions 2.13 through 2.17.x before 2.17.1), Ubuntu's crash reporting tool. The vulnerability arises from unsafe handling of core dumps and improper use of chroot and namespace features, particularly when Apport is triggered via a crafted /usr/share/apport/apport file in a container or namespace. Attackers can exploit race conditions, symlink attacks, and trust in attacker-controlled paths to escalate privileges to root or take ownership of arbitrary files. The vulnerability is especially severe in containerized environments and is exploitable by local users with user namespace capabilities.

This repository contains a single Metasploit module (Ruby file) that exploits a local privilege escalation vulnerability in the Apport (Ubuntu) and ABRT (Fedora) coredump handlers (CVE-2015-1318). The exploit targets systems where the coredump handler is configured to chroot and execute either /usr/share/apport/apport or /usr/libexec/abrt-hook-ccpp, and where unprivileged user namespaces are enabled. The module checks for the presence of a vulnerable configuration by reading /proc/sys/kernel/core_pattern and verifying the Apport or ABRT version. If the system is vulnerable, the module uploads a precompiled exploit binary and a custom payload (generated by Metasploit), executes the exploit to gain root privileges, and runs the payload as root. The exploit is operational and provides root access on affected systems. The structure is typical for a Metasploit local exploit module, with clear separation of initialization, vulnerability checking, and exploitation logic. The only file present is the exploit module itself.
