VULNERABILITY DESCRIPTION

Un-/Collapse All

This chapter describes all vulnerabilities (CVE-IDs) addressed in this security advisory. Wherever applicable, it also documents the product-specific impact of the individual vulnerabilities.

Vulnerability 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.

CWE	CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection')

Vulnerability 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.

CVSS v3.1 Base Score	7.8
CVSS v3.1 Vector	CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C

CWE	CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection')

Vulnerability 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.

CVSS v3.1 Base Score	6.6
CVSS v3.1 Vector	CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C
