CVE-2003-0509
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 · uneditedSQL injection vulnerability in Cyberstrong eShop 4.2 and earlier allows remote attackers to steal authentication information and gain privileges via the ProductCode parameter in (1) 10expand.asp, (2) 10browse.asp, and (3) 20review.asp.
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 confidenceSQL injection vulnerability in Cyberstrong eShop 4.2 and earlier allows remote attackers to inject malicious SQL queries through the ProductCode parameter in 10expand.asp, 10browse.asp, and 20review.asp files, potentially enabling authentication bypass and privilege escalation.

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.
-
Identify Cyberstrong eShop installationSearch the web server for files named 'eshop', 'cyberstrong', or common ASP e-commerce files. Check for directories containing '10expand.asp', '10browse.asp', or '20review.asp'. Look for the presence of an 'eshop.mdb' or similar Access database file typically bundled with Cyberstrong eShop.Affected if Cyberstrong eShop software is present on the server
-
Determine the installed versionExamine the main entry point of the eShop application (typically index.asp or a version file) for a version string. Check the source code of any admin or setup pages for version numbers. Look for a 'version.txt' or 'readme.txt' file in the application root.Affected if The version number found is 4.2 or lower, or no version information is available but the software appears to be Cyberstrong eShop
-
Locate vulnerable ASP filesSearch for the specific files '10expand.asp', '10browse.asp', and '20review.asp' within the eShop installation directory on the web server.Affected if Any of these three files exist in the application directory
-
Verify ProductCode parameter usageOpen each affected ASP file in a text editor and search for usage of 'ProductCode' as a request parameter (Request.QueryString, Request.Form, or Request). Look for dynamic SQL queries that incorporate this parameter without proper sanitization.Affected if The files contain code that passes the ProductCode parameter directly into SQL queries without visible input validation or parameterized queries
The environment is affected if Cyberstrong eShop version 4.2 or lower is installed and the vulnerable ASP files (10expand.asp, 10browse.asp, or 20review.asp) exist with the ProductCode parameter being used in unsanitized SQL queries.

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 dynamic SQL queries with parameterized queries or prepared statements in all three affected files, and implement strict input validation on the ProductCode parameter to prevent SQL injection attacks.
