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 remote code execution vulnerability exists when the Windows Print Spooler service improperly performs privileged file operations. An attacker who successfully exploited this vulnerability could run arbitrary code with SYSTEM privileges. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
