CENTUM series provided by Yokogawa Electric Corporation are vulnerable to cleartext storage of sensitive information. If an attacker who can login or access the computer where the affected product is installed tampers the password file stored in the computer, the user privilege which CENTUM managed may be escalated. As a result, the control system may be operated with the escalated user privilege. To exploit this vulnerability, the following prerequisites must be met: (1)An attacker has obtained user credentials where the affected product is installed, (2)CENTUM Authentication Mode is used for user authentication when CENTUM VP is used. The affected products and versions are as follows: CENTUM CS 1000, CENTUM CS 3000 (Including CENTUM CS 3000 Entry Class) R2.01.00 to R3.09.50, CENTUM VP (Including CENTUM VP Entry Class) R4.01.00 to R4.03.00, R5.01.00 to R5.04.20, and R6.01.00 and later, B/M9000 CS R5.04.01 to R5.05.01, and B/M9000 VP R6.01.01 to R7.04.51 and R8.01.01 and later

An unquoted search path vulnerability in Multiple Yokogawa products for Windows (Exaopc (R1.01.00 ? R3.77.00), Exaplog (R1.10.00 ? R3.40.00), Exaquantum (R1.10.00 ? R3.02.00 and R3.15.00), Exaquantum/Batch (R1.01.00 ? R2.50.40), Exasmoc (all revisions), Exarqe (all revisions), GA10 (R1.01.01 ? R3.05.01), and InsightSuiteAE (R1.01.00 ? R1.06.00)) allow local users to gain privileges via a Trojan horse executable file and execute arbitrary code with eleveted privileges.
A weakness in access controls in CENTUM CS 1000 all versions, CENTUM CS 3000 versions R3.09.50 and earlier, CENTUM CS 3000 Small versions R3.09.50 and earlier, CENTUM VP versions R6.03.10 and earlier, CENTUM VP Small versions R6.03.10 and earlier, CENTUM VP Basic versions R6.03.10 and earlier, Exaopc versions R3.75.00 and earlier, B/M9000 CS all versions, and B/M9000 VP versions R8.01.01 and earlier may allow a local attacker to exploit the message management function of the system. A CVSS v3 base score of 6.5 has been calculated; the CVSS vector string is (AV:L/AC:H/PR:L/UI:N/S:U/C:L/I:H/A:H).
