CVE-2017-16834
PNP4Nagios through 0.6.26 has /usr/bin/npcd and npcd.cfg owned by an unprivileged account but root code execution depends on these files, which allows local users to gain privileges by leveraging access to this unprivileged account.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.36%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
