CVE-2018-13797

Status: ModifiedCritical (9.8)—💥 PoC

The macaddress module before 0.2.9 for Node.js is prone to an arbitrary command injection flaw, due to allowing unsanitized input to an exec (rather than execFile) call.

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.
