Low risk5th percentile - higher than 5% of all known CVEs
Summary
SCALANCE LPE9403 devices with SINEMA Remote Connect Edge Client installed are vulnerable to an authentication bypass. A non-privileged local attacker can bypass the client's authentication and read and modify configuration parameters.
Risk Assessment
Authentication bypass could allow unauthorized modification of device configuration, potentially leading to network and data security breaches.
Recommendation
Update the software to version V2.1 HF0 or later and monitor local access to the devices.
Other vulnerabilities in SCALANCE LPE9403
See all- CVE-2023-27407Critical
A vulnerability has been identified in SCALANCE LPE9403 (All versions < V2.1). 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.
- CVE-2025-40583Medium
A vulnerability in SCALANCE LPE9403 (6GK5998-3GS00-2AC2) with SINEMA Remote Connect Edge Client installed (versions before V2.1 HF0) causes transmission of sensitive information in cleartext. A privileged local attacker could retrieve this information.
- CVE-2025-40582High
SCALANCE LPE9403 devices with SINEMA Remote Connect Edge Client installed do not properly sanitize configuration parameters. This allows a non-privileged local attacker to execute root commands on the device.
- CVE-2023-27409Low
SCALANCE LPE9403 (versions < V2.1) contains a path traversal vulnerability in the `deviceinfo` binary via the `mac` parameter. An authenticated attacker with SSH access can read the contents of any file named `address`.
- CVE-2023-27408Low
A vulnerability in SCALANCE LPE9403 (versions < V2.1) is that the `i2c` mutex file is created with permissions `-rw-rw-rw-`. An authenticated attacker with SSH access could interfere with the integrity of the mutex and the data it protects.
