CVE-2017-16834
CWE-732Published: November 16, 2017· Updated: Jun 17, 2026
7.8
CVSS v3.1
Official Description
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.
Technical Analysis
CVE-2017-16834 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 7.8.
