What it is

🚨 Out-of-band SQL injection lurking in the Performance Evaluation app could expose sensitive data just by altering one parameter! 🔥 Think of it like a secret vault where the guards are trained to ignore direct access attempts but are completely unaware of a hidden tunnel that leads right to the treasures inside. An attacker could exploit this sneaky access to pull out sensitive information without triggering any alarms. This vulnerability could allow an attacker to extract confidential user information from the database without any direct interaction with the application! Imagine the chaos if sensitive data gets leaked — personal details, evaluation results, all at the mercy of a crafty intruder. This is a critical risk that needs immediate attention!

Put simply

Think of it like a secret vault where the guards are trained to ignore direct access attempts but are completely unaware of a hidden tunnel that leads right to the treasures inside. An attacker could exploit this sneaky access to pull out sensitive information without triggering any alarms. The out-of-band SQL injection vulnerability in the 'Id_usuario' parameter of the Performance Evaluation application allows attackers to bypass direct application checks and retrieve database information via external channels.

What to do

This vulnerability could allow an attacker to extract confidential user information from the database without any direct interaction with the application! Imagine the chaos if sensitive data gets leaked — personal details, evaluation results, all at the mercy of a crafty intruder. This is a critical risk that needs immediate attention! Urgently patch to the latest version provided by the Gabinete Técnico de Programación to secure the application against this vulnerability.
