CVE-2011-4034

Status: ModifiedHigh (9.3)—

Buffer overflow in the Steema TeeChart ActiveX control, as used in Schneider Electric Vijeo Historian 4.30 and earlier, CitectHistorian 4.30 and earlier, and CitectSCADAReports 4.10 and earlier, allows remote attackers to execute arbitrary code or cause a denial of service 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).
