CVE-2017-14187

Status: ModifiedMedium (6.2)—💥 PoC

A local privilege escalation and local code execution vulnerability in Fortinet FortiOS 5.6.0 to 5.6.2, 5.4.0 to 5.4.8, and 5.2 and below versions allows attacker to execute unauthorized binary program contained on an USB drive plugged into a FortiGate via linking the aforementioned binary program to a command that is allowed to be run by the fnsysctl CLI command.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

💥 Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.

⚠️ GitHub proofs of concept are not verified: some are fake or contain malware. Never run them outside an isolated lab.
