CVE-2003-0702
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedUnknown vulnerability in an ISAPI plugin for ISS Server Sensor 7.0 XPU 20.16, 20.18, and possibly other versions before 20.19, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code in Internet Information Server (IIS) via a certain URL through SSL.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceISAPI plugin vulnerability in ISS Server Sensor 7.0 allows remote attackers to cause denial of service and possibly execute arbitrary code via specially crafted URLs through SSL. The vulnerability affects versions before 20.19.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check if ISS RealSecure Server Sensor is installedLook for the product in Windows Add/Remove Programs, or search for files named 'ServerSensor' or 'rs' in Program Files directories. Also check running services for 'RealSecure' or 'ISS' related services.Affected if The product ISS RealSecure Server Sensor is found on the system
-
Identify the installed version of ISS RealSecure Server SensorCheck the version information of the executable or service. Common paths include Program Files\ISS\RealSecure or similar. Right-click the main executable and view Properties > Version, or use 'wmic product get name,version' if listed.Affected if The version is 7.0 or any version earlier than 20.19
-
Verify the ISAPI plugin is enabledCheck IIS management console (inetmgr) for ISAPI filters or extensions related to 'ServerSensor' or 'rs'. Also check the IIS metabase.xml file for ISAPI filter mappings pointing to ISS components.Affected if An ISAPI filter or extension for ISS Server Sensor is registered and enabled in IIS
-
Confirm SSL/HTTPS is enabled on the IIS serverCheck IIS manager for SSL configuration on websites, or run 'cscript //nologo adsutil.vbs get /w3svc/N/SSLEnabled' where N is the site number. Also verify port 443 is listening.Affected if SSL is enabled and the server accepts HTTPS connections on port 443
If ISS RealSecure Server Sensor version 7.0 (or any version below 20.19) is installed with its ISAPI plugin enabled on an IIS server with SSL active, the environment is vulnerable to CVE-2003-0702.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate ISS Server Sensor to version 20.19 or later to patch the vulnerability. If updating is not immediately possible, consider blocking malicious SSL requests at the perimeter.
