OMRON CX-One CX-FLnet Node Name Heap-based Buffer Overflow Remote Code Execution Vulnerability
Vulnerability Details
This vulnerability allows remote attackers to execute arbitrary code on vulnerable 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 processing of FLN files. When parsing the Node Name field, the process does not properly validate the length of user-supplied data prior to copying it to a heap-based buffer.
