CVE-2006-4654
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 · uneditedFormat string vulnerability in Easy Address Book Web Server 1.2 allows remote attackers to cause a denial of service (crash) or "compromise the server" via encoded format string specifiers in the query string.
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 · high confidenceFormat string vulnerability in Easy Address Book Web Server 1.2 allows remote attackers to inject format string specifiers (e.g., %s, %x, %n) through the query string. This can manipulate format functions to read/write arbitrary memory, causing denial of service (crash) or potentially achieving remote code execution and server compromise.

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.
-
Confirm Easy Address Book Web Server is installedLook for the Easy Address Book Web Server executable (commonly named eabws.exe or similar) on the system, typically in Program Files or the application installation directory.Affected if The software is found on the system
-
Verify the installed version numberRight-click the executable file and view its Properties, or use a command like 'dir' or PowerShell to view file version information.Affected if The version is 1.2 exactly
-
Confirm the web service is running and accessibleCheck if the Easy Address Book Web Server process is running (tasklist or Services panel), then attempt to access the web interface via browser at the configured port (default often 80 or 8080).Affected if The web service is running and accepting HTTP requests
-
Identify if query string parameters are acceptedSend a test HTTP request to the server with any query string parameter (e.g., http://server:port/?test=value) and observe if the server processes it.Affected if The server accepts and processes query string parameters without sanitization
The system is affected if Easy Address Book Web Server version 1.2 is installed, the web service is running, and query string parameters are processed by the application.

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 dataReplace Easy Address Book Web Server with a current, actively maintained address book solution, as version 1.2 is obsolete and likely unpatched; if continued use is required, contact the vendor for patched versions or implement input validation to reject format string characters.
