Vulnerability from variot

The Omron CX-One Version 4.60 and prior is vulnerable to a stack-based buffer overflow, which may allow an attacker to remotely execute arbitrary code. Provided by OMRON Corporation CX-One There are multiple vulnerabilities in. ‥ * Untrusted pointer reference (CWE-822) - CVE-2020-27259 ‥ * Stack-based buffer overflow (CWE-121) - CVE-2020-27261 ‥ * Wrong type (CWE-843) - CVE-2020-27257The expected impact depends on each vulnerability, but it may be affected as follows. ‥ * Any memory pointer is referenced by a third party and arbitrary code is executed remotely. 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 NCI files by the CX-Position application. 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. ARC, etc. are all products. ARC is a software package for creating and maintaining file archives. CX-Protocol is one of the components used to create a serial communication protocol to communicate with standard serial devices. Omron CX-One etc. are the products of Japan Omron (Omron) company. Omron CX-One is an integrated toolkit. The following products and versions are affected: CX-Protocol Versions 2.02 and prior, CX-Server Versions 5.0.28 and prior, CX-Position Versions 2.52 and prior
