Description

This security bulletin contains information about 6 vulnerabilities.


1) Missing Support for Integrity Check (CVE-ID: CVE-2022-2793)

CWE-ID: CWE-353 - Missing Support for Integrity Check

CVSSv4: CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:A/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local attacker to compromise the target system.

The vulnerability exists due to improper authentication or authorization of data packets after establishing a connection for the SRTP protocol. An attacker with physical access can bypass authentication on the target system.


2) Improper access control (CVE-ID: CVE-2022-2792)

CWE-ID: CWE-284 - Improper Access Control

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:A/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to gain unauthorized access to otherwise restricted functionality.

The vulnerability exists due to the affected application stores project data in a directory with improper access control lists. A local user can bypass implemented security restrictions and gain unauthorized access to the application.


3) Arbitrary file upload (CVE-ID: CVE-2022-2791)

CWE-ID: CWE-434 - Unrestricted Upload of File with Dangerous Type

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:A/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/E:U/U:Clear


The vulnerability allows a local user to compromise vulnerable system.

The vulnerability exists due to the affected application will upload any file written into the PLC logic folder to the connected PLC. A local user can upload a malicious file and execute it on the server.


4) Improper Verification of Cryptographic Signature (CVE-ID: CVE-2022-2790)

CWE-ID: CWE-347 - Improper Verification of Cryptographic Signature

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:A/VC:N/VI:H/VA:N/SC:N/SI:H/SA:N/E:U/U:Clear


The vulnerability allows a local user to compromise the target system.

The vulnerability exists due to the affected application does not properly verify compiled logic (PDT files) and data blocks data (BLD/BLK files). A local user can bypass authentication on the target system.


5) Insufficient verification of data authenticity (CVE-ID: CVE-2022-2789)

CWE-ID: CWE-345 - Insufficient Verification of Data Authenticity

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:A/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local attacker to compromise the target system.

The vulnerability exists due to the affected product can display logic that is different than the compiled logic. A local attacker can bypass authentication on the target system.


6) Path traversal (CVE-ID: CVE-2022-2788)

CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote attacker to perform directory traversal attacks.

The vulnerability exists due to input validation error when processing directory traversal sequences. A remote attacker can perform a ZipSlip attack through an upload procedure and execute arbitrary code on the target system.
