CVE-2016-4523

Status: AnalyzedHigh (7.5)⚠ Active exploitation

The WAP interface in Trihedral VTScada (formerly VTS) 8.x through 11.x before 11.2.02 allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via unspecified vectors.

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).

CISA KEV — actively exploited

🎯 ATT&CK techniques

How this vulnerability is exploited and what the attacker gains, in MITRE ATT&CK terms.

Vector AV:N/PR:N/UI:N y CWE-125 (buffer read) en interfaz web pública confirman T1190. Out-of-bounds read causa crash → T1499.004 (denial of service por agotamiento de aplicación).

Inferred by our analysis agent from the official description, CVSS vector and CWE, and checked by a supervisor. May contain errors.
