Description

This security bulletin contains information about 7 secuirty vulnerabilities.


1) Missing Authentication for Critical Function (CVE-ID: CVE-2023-22803)

The vulnerability allows a remote attacker to manipulate PLC configuration.

The vulnerability exists due to missing authorization. A remote attacker can send a specially crafted request and set PLC to an mode mode.


2) Missing Authentication for Critical Function (CVE-ID: CVE-2023-22804)

The vulnerability allows a remote attacker to compromise the affected device.

The vulnerability exists due to missing authorization. A remote non-authenticated attacker can send a specially crafted request to the device, create an administrative account and take full control over the device.


3) Improper access control (CVE-ID: CVE-2023-22805)

The vulnerability allows a remote attacker to deny access to users.

The vulnerability exists due to improper access restrictions. A remote attacker can disable read access to device users.


4) Cleartext transmission of sensitive information (CVE-ID: CVE-2023-22806)

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to software uses insecure communication channel (own unencrypted XGT protocol) to transmit sensitive information. A remote attacker with ability to intercept network traffic can gain access to sensitive data.


5) Improper Verification of Source of a Communication Channel (CVE-ID: CVE-2023-22807)

The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists due to usage of XGT protocol for communication purposes with PLC. A remote attacker can perform MitM attack.


6) Improper access control (CVE-ID: CVE-2023-0102)

The vulnerability allows a remote attacker to delete arbitrary files on the device.

The vulnerability exists due to improper access restrictions. A remote attacker can send a specially crafted request and delete arbitrary files on the device.


7) Out-of-bounds read (CVE-ID: CVE-2023-0103)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary condition. A remote attacker can send specially crafted data to the device, trigger an out-of-bounds read error and perform a denial of service (DoS) attack.
