CVE-2015-0987
Omron CX-One CX-Programmer before 9.6, CJ2M PLC devices before 2.1, and CJ2H PLC devices before 1.5 rely on cleartext password transmission, which allows remote attackers to obtain sensitive information by sniffing the network during a PLC unlock request.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.17%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
