What it is

🚨 A crafty out-of-band SQL injection is lurking in the Performance Evaluation app, allowing attackers to sneak sensitive data from your database without a trace! 🔥 Think of it like a secretive courier service that takes your important documents and sends them out without your knowledge — a trusted delivery person delivering sensitive info to unauthorized recipients! If exploited, an attacker could access confidential information stored in your database, potentially leading to data breaches that compromise user privacy and trust. The fallout could be absolutely devastating, putting both your organization and its users at risk. 🌪️

Put simply

Think of it like a secretive courier service that takes your important documents and sends them out without your knowledge — a trusted delivery person delivering sensitive info to unauthorized recipients! This vulnerability exists in the 'Id_usuario' parameter on the '/evaluacion_acciones_ver_auto.aspx' page, enabling attackers to execute SQL queries that extract data through external channels, rather than through the application itself.

What to do

If exploited, an attacker could access confidential information stored in your database, potentially leading to data breaches that compromise user privacy and trust. The fallout could be absolutely devastating, putting both your organization and its users at risk. 🌪️ It's crucial to patch the application to the latest version and implement input validation to sanitize the 'Id_usuario' parameter. Regularly audit your database access logs and limit permissions for sensitive data access to mitigate potential risks. 🛡️ You've got this! Stay vigilant, follow the steps, and you’ll ensure your data is secure in no time! 🔒
