CVE-2012-0226
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 Invensys Wonderware Information Server 4.0 SP1 and 4.5 allows remote attackers to execute arbitrary SQL commands via unspecified vectors.
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 confidenceSQL injection vulnerability in Invensys Wonderware Information Server versions 4.0 SP1 and 4.5 allows remote attackers to execute arbitrary SQL commands via unspecified input vectors. The vulnerability is exploitable without authentication due to improper input sanitization in the application's handling of user-supplied data.

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.
-
Verify Wonderware Information Server installationCheck for the product in Windows Add/Remove Programs, or look for the installation directory under C:\Program Files\Wonderware\Information Server or similar paths.Affected if Wonderware Information Server is installed and no security patches have been applied.
-
Determine installed versionLocate the version information in the registry key HKLM\SOFTWARE\Wonderware\InformationServer\Version or check the 'About' information in the Wonderware Information Server web interface if accessible.Affected if The installed version is exactly 4.0 or 4.5 (including 4.0 SP1).
-
Confirm web service is runningCheck if the Wonderware Information Server web service (typically running on IIS) is active by accessing the server's web interface or checking the IIS service status.Affected if The web interface is accessible and the application is running.
-
Assess network exposureDetermine if the IIS web server hosting Wonderware Information Server is exposed to external or untrusted networks by reviewing firewall rules, network configurations, and listening ports (typically ports 80/443).Affected if The web interface is reachable from untrusted networks without compensating controls.
The environment is affected if Wonderware Information Server version 4.0 or 4.5 is installed with the web interface running and accessible, since the SQL injection is exploitable without authentication through the application's input handling.

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 dataApply vendor patches if available; otherwise, implement input validation and parameterized queries to remediate the injection point, and consider deploying a WAF to block SQL injection attacks until a permanent fix is implemented.
