CVE-2025-12744 is a local privilege escalation vulnerability in the ABRT daemon caused by improper neutralization of untrusted input before constructing a shell command. According to the provided content, ABRT mishandles user-supplied mount information by copying up to 12 characters from attacker-controlled input into the command template "docker inspect %s" without proper validation or sanitization. Because shell metacharacters are not neutralized, an unprivileged local user can inject command syntax into the constructed shell command. Since the ABRT process runs as root, successful exploitation results in execution of attacker-controlled commands with root privileges.

This repository contains a proof-of-concept exploit for CVE-2025-12744, a local privilege escalation vulnerability affecting Fedora Linux (versions 43 and below). The exploit is implemented in a single Python script (abrt_root.py) and leverages a command injection flaw in the ABRT daemon, which listens on the UNIX socket /var/run/abrt/abrt.socket. The exploit works in multiple stages: it first creates a helper script in the current directory that, when executed, uses systemd-run to append the current user to /etc/sudoers with NOPASSWD privileges. It then stages a second script (written character-by-character to /q) that chains execution to the helper script. The exploit communicates with the ABRT daemon via its UNIX socket, sending specially crafted payloads to trigger the vulnerability and execute the staged scripts. If successful, the current user is granted root privileges via sudo. The repository is structured simply, with a license, a README providing usage instructions and context, and the main exploit script.
