Siemens has released a new version for SINEMA Remote Connect Client and recommends to update to the latest version. CVE-2024-39567: The system service of affected applications is vulnerable to command injection due to missing server side input sanitation when loading VPN configurations. This could allow an authenticated local attacker to execute arbitrary code with system privileges. CVE-2024-39568: The system service of affected applications is vulnerable to command injection due to missing server side input sanitation when loading proxy configurations. This could allow an authenticated local attacker to execute arbitrary code with system privileges. CVE-2024-39569: The system service of affected applications is vulnerable to command injection due to missing server side input sanitation when loading VPN configurations. This could allow an administrative remote attacker running a corresponding SINEMA Remote Connect Server to execute arbitrary code with system privileges on the client system.
