CVE-2017-5177

Status: ModifiedHigh (7.5)—💥 Exploit

A Stack Buffer Overflow issue was discovered in VIPA Controls WinPLC7 5.0.45.5921 and prior. A stack-based buffer overflow vulnerability has been identified, where an attacker with a specially crafted packet could overflow the fixed length buffer. This could allow remote code execution.

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.
