Status: ModifiedMedium (5)—💥 Exploit

The logging capability for unicast and multicast transmissions in the ISAPI extension for Microsoft Windows Media Services in Microsoft Windows NT 4.0 and 2000, nsiislog.dll, allows remote attackers to cause a denial of service in Internet Information Server (IIS) and execute arbitrary code via a certain network 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).

💥 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.
