Status: ModifiedHigh (9.3)—💥 Exploit

Stack-based buffer overflow in VATDecoder.VatCtrl.1 ActiveX control in (1) 4xem VatCtrl Class (VATDecoder.dll 1.0.0.27 and 1.0.0.51), (2) D-Link MPEG4 SHM Audio Control (VAPGDecoder.dll 1.7.0.5), (3) Vivotek RTSP MPEG4 SP Control (RtspVapgDecoderNew.dll 2.0.0.39), and possibly other products, allows remote attackers to execute arbitrary code via a long Url property. NOTE: some of these details are obtained from third party information.

CVSS

Version: 2.0
Vector: AV:N/AC:M/Au:N/C:C/I:C/A:C
Base score: 9.3

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 7.14%
Percentile among all scored CVEs: 94
Score date: 10/7/2026

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.
