Description

A vulnerability has been identified in SCALANCE LPE9403 (All versions < V2.1). 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 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
