CVE-2017-16834

24
FAUCET Score

CVE-2017-16834 affects PNP4Nagios through version 0.6.26, stemming from insecure file permissions where critical root-executed files are owned by an unprivileged account. This allows a local attacker with access to that unprivileged account to achieve root code execution, leading to high impact on confidentiality, integrity, and availability. Despite its high CVSS score of 7.8, there is no evidence of active exploitation, publicly available exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage, suggesting a low current exploitation risk.
