CVE-2026-109813
A hard-coded cryptographic key vulnerability exists in the `/usr/bin/sysman` of some of Moxa's industrial computing products.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.16%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
