Nmap calls it coldfusion-auth — the authentication port from Allaire ColdFusion's Advanced Security, paired with 44443.
IANA has no assignment for 44442, but Nmap's service database names it coldfusion-auth, from the Advanced Security feature Allaire built into ColdFusion using Netegrity SiteMinder; 44442 and 44443 were its pair of authentication ports. That feature was dropped from ColdFusion long ago, so an open 44442 today is more likely to be an unrelated service than a live ColdFusion security server. Nmap's measured open frequency is about 0.016%, among the lowest in its default scan set.
Do not expose
It is an authentication back-channel between application-server components, not a public interface — and if it really is the Allaire-era service, it is two decades unpatched.
