Affected: Rockwell Automation FactoryTalk View SE

In all versions of FactoryTalk View SE, after bypassing memory corruption mechanisms found in the operating system, a local, authenticated attacker may corrupt the associated memory space allowing for arbitrary code execution. Rockwell Automation recommends applying patch 1126290. Before installing this patch, the patch rollup dated 06 Apr 2020 or later MUST be applied. 1066644 – Patch Roll-up for CPR9 SRx.

The affected product does not properly validate input of filenames within a project directory. A remote, unauthenticated attacker may be able to execute a crafted file on a remote endpoint that may result in remote code execution (RCE).CVE-2020-12029 has been assigned to this vulnerability. A CVSS v3 base score of 9.0 has been assigned; the CVSS vector string is (AV:L/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:N). After bypassing memory corruption mechanisms found in the operating system, a local, authenticated attacker may corrupt the associated memory space allowing for arbitrary code execution.CVE-2020-12031 has been assigned to this vulnerability. A CVSS v3 base score of 7.5 has been assigned; the CVSS vector string is (AV:L/AC:H/PR:L/UI:R/S:C/C:H/I:H/A:H). A remote, authenticated attacker may be able to utilize certain handlers to interact with the data on the remote endpoint since those handlers do not enforce appropriate permissions.CVE-2020-12028 has been assigned to this vulnerability. A CVSS v3 base score of 7.3 has been assigned; the CVSS vector string is (AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:N). The affected product discloses the hostnames and file paths for certain files within the system. A remote, authenticated attacker may be able to leverage this information for reconnaissance efforts.CVE-2020-12027 has been assigned to this vulnerability. A CVSS v3 base score of 4.3 has been assigned; the CVSS vector string is (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N).
