Vulnerabilities

A vulnerability has been found in Vnet/IP Interface Package provided by Yokogawa Electric Corporation. If affected product receives maliciously crafted packets, Vnet/IP software stack process may be terminated. The affected products and versions are as follows: Vnet/IP Interface Package (for CENTUM VP R6 VP6C3300, CENTUM VP R7 VP7C3300) R1.07.00 or earlier

A vulnerability has been found in FAST/TOOLS provided by Yokogawa Electric Corporation. This product supports weak cryptographic algorithms, potentially allowing an attacker to decrypt communications with the web server. The affected products and versions are as follows: FAST/TOOLS (Packages: RVSVRN, UNSVRN, HMIWEB, FTEES, HMIMOB) R9.01 to R10.04

A vulnerability of Uncontrolled Resource Consumption has been identified in STARDOM provided by Yokogawa Electric Corporation. This vulnerability may allow to a remote attacker to cause a denial-of-service condition to the FCN/FCJ controller by sending a crafted packet. While sending the packet, the maintenance homepage of the controller could not be accessed. Therefore, functions of the maintenance homepage, changing configuration, viewing logs, etc. are not available. But the controller’s operation is not stopped by the condition. The affected products and versions are as follows: STARDOM FCN/FCJ R1.01 to R4.31.

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

Stack-based buffer overflow in WTViewerE series WTViewerE 761941 from 1.31 to 1.61 and WTViewerEfree from 1.01 to 1.52 allows an attacker to cause the product to crash by processing a long file name.

CENTUM VP / CS 3000 controller FCS (CP31, CP33, CP345, CP401, and CP451) contains an issue in processing communication packets, which may lead to resource consumption. If this vulnerability is exploited, an attacker may cause a denial of service (DoS) condition in ADL communication by sending a specially crafted packet to the affected product.

Use of insufficiently random values vulnerability exists in Vnet/IP communication module VI461 of YOKOGAWA Wide Area Communication Router (WAC Router) AW810D, which may allow a remote attacker to cause denial-of-service (DoS) condition by sending a specially crafted packet.

Cleartext transmission of sensitive information vulnerability exists in STARDOM FCN Controller and FCJ Controller R1.01 to R4.31, which may allow an adjacent attacker to login the affected products and alter device configuration settings or tamper with device firmware.

Violation of secure design principles exists in the communication of CAMS for HIS. Affected products and versions are CENTUM series where LHS4800 is installed (CENTUM CS 3000 and CENTUM CS 3000 Small R3.08.10 to R3.09.00), CENTUM series where CAMS function is used (CENTUM VP, CENTUM VP Small, and CENTUM VP Basic R4.01.00 to R4.03.00), CENTUM series regardless of the use of CAMS function (CENTUM VP, CENTUM VP Small, and CENTUM VP Basic R5.01.00 to R5.04.20 and R6.01.00 to R6.09.00), Exaopc R3.72.00 to R3.80.00 (only if NTPF100-S6 'For CENTUM VP Support CAMS for HIS' is installed), B/M9000 CS R5.04.01 to R5.05.01, and B/M9000 VP R6.01.01 to R8.03.01). If an adjacent attacker successfully compromises a computer using CAMS for HIS software, they can use credentials from the compromised machine to access data from another machine using CAMS for HIS software. This can lead to a disabling of CAMS for HIS software functions on any affected machines, or information disclosure/alteration.

Improper authentication vulnerability in the communication protocol provided by AD (Automation Design) server of CENTUM VP R6.01.10 to R6.09.00, CENTUM VP Small R6.01.10 to R6.09.00, CENTUM VP Basic R6.01.10 to R6.09.00, and B/M9000 VP R8.01.01 to R8.03.01 allows an attacker to use the functions provided by AD server. This may lead to leakage or tampering of data managed by AD server.

In Yokogawa WideField3 R1.01 - R4.03, a buffer overflow could be caused when a user loads a maliciously crafted project file.
