CVE-2023-22424 1 Jtekt 1 Kostac Plc Programming Software 2023-03-13 N/A 7.8 HIGH
Use-after-free vulnerability exists in Kostac PLC Programming Software (Former name: Koyo PLC Programming Software) Version 1.6.9.0 and earlier. With the abnormal value given as the maximum number of columns for the PLC program, the process accesses the freed memory. As a result, opening a specially crafted project file may lead to information disclosure and/or arbitrary code execution.
CVE-2023-22419 1 Jtekt 1 Kostac Plc Programming Software 2023-03-13 N/A 7.8 HIGH
Out-of-bounds read vulnerability exists in Kostac PLC Programming Software (Former name: Koyo PLC Programming Software) Version 1.6.9.0 and earlier. When processing a comment block in stage information, the end of data cannot be verified and out-of-bounds read occurs. As a result, opening a specially crafted project file may lead to information disclosure and/or arbitrary code execution.
CVE-2023-22421 1 Jtekt 1 Kostac Plc Programming Software 2023-03-13 N/A 7.8 HIGH
Out-of-bounds read vulnerability exists in Kostac PLC Programming Software (Former name: Koyo PLC Programming Software) Version 1.6.9.0 and earlier. The insufficient buffer size for the PLC program instructions leads to out-of-bounds read. As a result, opening a specially crafted project file may lead to information disclosure and/or arbitrary code execution.
CVE-2023-22360 1 Jtekt 1 Screen Creator Advance 2 2023-02-27 N/A 7.8 HIGH
Use-after free vulnerability exists in Screen Creator Advance 2 Ver.0.1.1.4 Build01 and earlier due to lack of error handling process even when an error was detected. Having a user of Screen Creator Advance 2 to open a specially crafted project file may lead to information disclosure and/or arbitrary code execution.
CVE-2023-22353 1 Jtekt 1 Screen Creator Advance 2 2023-02-27 N/A 7.8 HIGH
Out-of-bound read vulnerability exists in Screen Creator Advance 2 Ver.0.1.1.4 Build01 and earlier because the end of data cannot be verified when processing control management information. Having a user of Screen Creator Advance 2 to open a specially crafted project file may lead to information disclosure and/or arbitrary code execution.
CVE-2023-22350 1 Jtekt 1 Screen Creator Advance 2 2023-02-27 N/A 7.8 HIGH
Out-of-bound read vulnerability exists in Screen Creator Advance 2 Ver.0.1.1.4 Build01 and earlier because the end of data cannot be verified when processing parts management information. Having a user of Screen Creator Advance 2 to open a specially crafted project file may lead to information disclosure and/or arbitrary code execution.
CVE-2023-22349 1 Jtekt 1 Screen Creator Advance 2 2023-02-27 N/A 7.8 HIGH
Out-of-bound read vulnerability exists in Screen Creator Advance 2 Ver.0.1.1.4 Build01 and earlier because the end of data cannot be verified when processing screen management information. Having a user of Screen Creator Advance 2 to open a specially crafted project file may lead to information disclosure and/or arbitrary code execution.
CVE-2023-22347 1 Jtekt 1 Screen Creator Advance 2 2023-02-27 N/A 7.8 HIGH
Out-of-bound read vulnerability exists in Screen Creator Advance 2 Ver.0.1.1.4 Build01 and earlier because the end of data cannot be verified when processing file structure information. Having a user of Screen Creator Advance 2 to open a specially crafted project file may lead to information disclosure and/or arbitrary code execution.
CVE-2023-22346 1 Jtekt 1 Screen Creator Advance 2 2023-02-27 N/A 7.8 HIGH
Out-of-bound read vulnerability exists in Screen Creator Advance 2 Ver.0.1.1.4 Build01 and earlier because the end of data cannot be verified when processing template information. Having a user of Screen Creator Advance 2 to open a specially crafted project file may lead to information disclosure and/or arbitrary code execution.
CVE-2023-22345 1 Jtekt 1 Screen Creator Advance 2 2023-02-27 N/A 7.8 HIGH
Out-of-bound write vulnerability exists in Screen Creator Advance 2 Ver.0.1.1.4 Build01 and earlier due to lack of error handling process when out of specification errors are detected. Having a user of Screen Creator Advance 2 to open a specially crafted project file may lead to information disclosure and/or arbitrary code execution.
CVE-2021-27477 1 Jtekt 44 2port-efr, 2port-efr Firmware, Fl\/et-t-v2h and 41 more 2022-10-07 7.8 HIGH 7.5 HIGH
When JTEKT Corporation TOYOPUC PLC versions PC10G-CPU, 2PORT-EFR, Plus CPU, Plus EX, Plus EX2, Plus EFR, Plus EFR2, Plus 2P-EFR, PC10P-DP, PC10P-DP-IO, Plus BUS-EX, Nano 10GX, Nano 2ET,PC10PE, PC10PE-16/16P, PC10E, FL/ET-T-V2H, PC10B,PC10B-P, Nano CPU, PC10P, and PC10GE receive an invalid frame, the outside area of a receive buffer for FL-net are overwritten. As a result, the PLC CPU detects a system error, and the affected products stop.
CVE-2022-29958 1 Jtekt 34 Nano 10gx Tuc-1157, Nano 10gx Tuc-1157 Firmware, Nano Cpu Tuc-6941 and 31 more 2022-08-03 N/A 9.8 CRITICAL
JTEKT TOYOPUC PLCs through 2022-04-29 do not ensure data integrity. They utilize the unauthenticated CMPLink/TCP protocol for engineering purposes, including downloading projects and control logic to the PLC. Control logic is downloaded to the PLC on a block-by-block basis with a given memory address and a blob of machine code. The logic that is downloaded to the PLC is not cryptographically authenticated, allowing an attacker to execute arbitrary machine code on the PLC's CPU module in the context of the runtime. In the case of the PC10G-CPU, and likely for other CPU modules of the TOYOPUC family, a processor without MPU or MMU is used and this no memory protection or privilege-separation capabilities are available, giving an attacker full control over the CPU.
CVE-2022-29951 1 Jtekt 34 Nano 10gx Tuc-1157, Nano 10gx Tuc-1157 Firmware, Nano Cpu Tuc-6941 and 31 more 2022-08-02 N/A 9.1 CRITICAL
JTEKT TOYOPUC PLCs through 2022-04-29 mishandle authentication. They utilize the CMPLink/TCP protocol (configurable on ports 1024-65534 on either TCP or UDP) for a wide variety of engineering purposes such as starting and stopping the PLC, downloading and uploading projects, and changing configuration settings. This protocol does not have any authentication features, allowing any attacker capable of communicating with the port in question to invoke (a subset of) desired functionality.
CVE-2021-33011 1 Jtekt 54 2port-efr Thu-6404, 2port-efr Thu-6404 Firmware, Ef10 Tcu-6982 and 51 more 2021-09-23 3.3 LOW 4.3 MEDIUM
All versions of the afffected TOYOPUC-PC10 Series,TOYOPUC-Plus Series,TOYOPUC-PC3J/PC2J Series, TOYOPUC-Nano Series products may not be able to properly process an ICMP flood, which may allow an attacker to deny Ethernet communications between affected devices.
