CVE-2012-4689

Status: ModifiedMedium (4.3)—

Integer overflow in CimWebServer.exe in GE Intelligent Platforms Proficy HMI/SCADA - CIMPLICITY 4.01 through 8.0, and Proficy Process Systems with CIMPLICITY, allows remote attackers to cause a denial of service (daemon crash) via a malformed HTTP request.

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).
