  # Exploit Title: Advanced Host Monitor v12.56 - Unquoted Service Path # Date: 2023-04-23 # CVE: CVE-2023-2417 # Exploit Author: MrEmpy # Vendor Homepage: https://www.ks-soft.net # Software Link: https://www.ks-soft.net/hostmon.eng/downpage.htm # Version: > 12.56 # Tested on: Windows 10 21H2     Title: ================ Advanced Host Monitor > 12.56 - Unquoted Service Path     Summary: ================ An unquoted service path vulnerability has been discovered in Advanced Host Monitor version > 12.56 affecting the executable "C:\Program Files (x86)\HostMonitor\RMA-Win\rma_active.exe" . This vulnerability occurs when the service's path is misconfigured, allowing an attacker to run a malicious file instead of the legitimate executable associated with the service.   An attacker with local user privileges could exploit this vulnerability to replace the legitimate RMA-Win\rma_active.exe service executable with a malicious file of the same name and located in a directory that has a higher priority than the legitimate directory. That way, when the service starts, it will run the malicious file instead of the legitimate executable, allowing the attacker to execute arbitrary code, gain unauthorized access to the compromised system, or stop the service from functioning.   To exploit this vulnerability, an attacker would need local access to the system and the ability to write and replace files on the system. The vulnerability can be mitigated by correcting the service path to correctly quote the full path of the executable, including quotation marks. Furthermore, it is recommended that users keep software updated with the latest security updates and limit physical and network access to their systems to prevent malicious attacks.     Proof of Concept: ================   C:\>sc qc ActiveRMAService [SC] QueryServiceConfig SUCCESS   SERVICE_NAME: ActiveRMAService TYPE : 110WIN32_OWN_PROCESS (interactive) START_TYPE : 2 AUTO_START ERROR_CONTROL: 1 NORMAL BINARY_PATH_NAME : C:\Program Files (x86)\HostMonitor\RMA-Win\rma_active.exe /service LOAD_ORDER_GROUP : TAG: 0 DISPLAY_NAME : KS Active Remote Monitoring Agent DEPENDENCIES : SERVICE_START_NAME : LocalSystem
