CVE-2007-2526

Status: ModifiedHigh (9.3)—💥 Exploit

Heap-based buffer overflow in the ConnectAsyncEx function in VNC Viewer ActiveX control (scvncctrl.dll) in the SmartCode VNC Manager 3.6 allows remote attackers to execute arbitrary code via a long argument.

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.
