GENERAL SECURITY RECOMMENDATIONS

As a general security measure, Siemens strongly recommends to protect network access to devices with appropriate mechanisms. In order to operate the devices in a protected IT environment, Siemens recommends to configure the environment according to Siemens' operational guidelines for Industrial Security (Download: https://www.siemens.com/cert/operational-guidelines-industrial-security), and to follow the recommendations in the product manuals. Additional information on Industrial Security by Siemens can be found at: https://www.siemens.com/industrialsecurity

PRODUCT DESCRIPTION

SCALANCE LPE9000 (Local Processing Engine) extends the SCALANCE family portfolio by a component that provides computing power for a wide range of applications in the network, close to the process – Edge Computing.

VULNERABILITY CLASSIFICATION

The vulnerability classification has been performed by using the CVSS scoring system in version 3.1 (CVSS v3.1) (https://www.first.org/cvss/). The CVSS environmental score is specific to the customer’s environment and will impact the overall CVSS score. The environmental score should therefore be individually defined by the customer to accomplish final scoring.

An additional classification has been performed using the CWE classification, a community-developed list of common software security weaknesses. This serves as a common language and as a baseline for weakness identification, mitigation, and prevention efforts. A detailed list of CWE classes can be found at: https://cwe.mitre.org/.

Vulnerability CVE-2023-27407

The web based management of affected device does not properly validate user input, making it susceptible to command injection. This could allow an authenticated remote attacker to access the underlying operating system as the root user.

CVSS v3.1 Base Score	9.9
CVSS Vector	CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/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-2023-27408

The i2c mutex file is created with the permissions bits of -rw-rw-rw-. This file is used as a mutex for multiple applications interacting with i2c. This could allow an authenticated attacker with access to the SSH interface on the affected device to interfere with the integrity of the mutex and the data it protects.

CVSS v3.1 Base Score	3.3
CVSS Vector	CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N/E:P/RL:O/RC:C
CWE	CWE-378: Creation of Temporary File With Insecure Permissions

Vulnerability CVE-2023-27409

A path traversal vulnerability was found in the deviceinfo binary via the mac parameter. This could allow an authenticated attacker with access to the SSH interface on the affected device to read the contents of any file named address.

CVSS v3.1 Base Score	2.5
CVSS Vector	CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:N/E:P/RL:O/RC:C
CWE	CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

Vulnerability CVE-2023-27410

A heap-based buffer overflow vulnerability was found in the edgebox_web_app binary. The binary will crash if supplied with a backup password longer than 255 characters. This could allow an authenticated privileged attacker to cause a denial of service.

CVSS v3.1 Base Score	2.7
CVSS Vector	CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:L/E:P/RL:O/RC:C
CWE	CWE-122: Heap-based Buffer Overflow
