PC Worx / -Express is vulnerable to a “zip slip” style vulnerability when loading a project file.
Access to the Apache web server being installed as part of the FL MGUARD DM on Microsoft Windows does not require login credentials even if configured during installation.
A device on the same network as the controller sending a special crafted JSON request to the /auth/access-token endpoint may cause the controller to restart (CWE-20).
UPDATE A
The CVSS score has been raised from 7.7 (CVSS:3.0:AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H) to 9.1 (CVSS:3.0:AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H)
Third party Niche Ethernet stack has several vulnerabilities announced by the security researcher’s community.
Phoenix Contact Classic Line industrial controllers are developed and designed for the use in closed industrial networks. The communication protocols and device access do not feature authentication measures. Remote attackers can use specially crafted IP packets to cause a Denial of Service or a Breach of Integrity of the PLC.
A Denial of Service and a CA Check Problem have been identified in multiple openSSL 1.1.1 versions, which are utilized in the Phoenix Contact products listed above.
The vulnerability is a Time-of-Check-Time-of-Use (CWE-367) issue which allows an attacker with access to the firmware update file to overwrite it after it has been verified (but before installation is completed), which consequently allows installing an arbitrary firmware update, bypassing the cryptographic signature check mechanism.
Multiple vulnerabilities have been discovered in the current firmware of the PHOENIX CONTACT FL SWITCH SMCS series switches.
