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. • https://jvn.jp/en/vu/JVNVU98917488 https://www.electronics.jtekt.co.jp/en/topics/202302035233 https://www.electronics.jtekt.co.jp/jp/topics/2023020313454 • CWE-787: Out-of-bounds Write •

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. JTEKT TOYOPUC PLC versiones hasta 29-04-2022, manejan inapropiadamente la autenticación. Usan el protocolo CMPLink/TCP (configurable en los puertos 1024-65534 en TCP o UDP) para una amplia variedad de propósitos de ingeniería tales como el arranque y la parada del PLC, la descarga y la carga de proyectos, y el cambio de los ajustes de configuración. • https://www.cisa.gov/uscert/ics/advisories/icsa-22-172-02 https://www.forescout.com/blog • CWE-306: Missing Authentication for Critical Function •

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. • https://www.cisa.gov/uscert/ics/advisories/icsa-22-172-02 https://www.forescout.com/blog • CWE-345: Insufficient Verification of Data Authenticity •
CVSS: 7.8EPSS: 0%CPEs: 5EXPL: 0CVE-2022-27648 – KOYO Screen Creator SCA2 File Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2022-27648
This vulnerability allows remote attackers to execute arbitrary code on affected installations of KOYO Screen Creator 0.1.1.1. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of SCA2 files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. • https://www.koyoele.co.jp/en/topics/202203154994 https://www.zerodayinitiative.com/advisories/ZDI-22-543 • CWE-121: Stack-based Buffer Overflow •
