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 Portal del Empleado installationLocate the Summar Software Portal del Empleado application in your web server directories. Look for the /MemberPages/quienesquien.aspx file or the 'Portal del Empleado' web application in your IIS/Apache/web server configuration.Affected if Portal del Empleado is not installed (you are not affected)
-
Determine the installed versionCheck the application's version through assembly metadata, web.config files, version headers, or an 'About' page within the Portal del Empleado. Compare your version against any affected version ranges provided by the vendor.Affected if The installed version falls within an affected range and you have not applied vendor patches
-
Verify the vulnerable page is accessibleAttempt to access the /MemberPages/quienesquien.aspx endpoint via HTTP. A successful HTTP 200 response indicates the page exists and is reachable.Affected if The page returns a 200 response and is accessible without authentication restrictions
-
Test parameter processingSend a crafted POST request to /MemberPages/quienesquien.aspx with the ctl00$ContentPlaceHolder1$filtroNombre parameter. Observe if the application reflects unsanitized input or returns SQL error messages.Affected if The application processes the parameter without proper input validation or parameterized queries
You are affected if Summar Software Portal del Empleado is installed, your version matches the affected range, and the /MemberPages/quienesquien.aspx page with the ctl00$ContentPlaceHolder1$filtroNombre parameter is accessible and processes user input unsafely.

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 dataImplement parameterized queries or prepared statements for all database operations using the affected parameter. Apply strict input validation and sanitization on user-supplied data before incorporating it into SQL queries.
