SSA-325383 V1.0: Multiple Vulnerabilities in SCALANCE LPE9403 before V2.1


The vulnerability classification has been performed by using the CVSS scoring system in version 3.1 (CVSS v3.1) ( 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:

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
