Omron CX-One CX-Position NCI File Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Omron CX-One. 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 in the CX-Position application. When parsing the B_PLC_NAME element, the process does not properly validate 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.
