Description
This security bulletin contains information about 7 vulnerabilities.
1) Missing Authentication for Critical Function (CVE-ID: CVE-2023-22803)
CWE-ID: CWE-306 - Missing Authentication for Critical Function
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
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)
CWE-ID: CWE-306 - Missing Authentication for Critical Function
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
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)
CWE-ID: CWE-284 - Improper Access Control
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green
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)
CWE-ID: CWE-319 - Cleartext Transmission of Sensitive Information
CVSSv4: CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
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)
CWE-ID: CWE-940 - Improper Verification of Source of a Communication Channel
CVSSv4: CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Amber
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)
CWE-ID: CWE-284 - Improper Access Control
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
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)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
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.
