Prior to 2.20.0, pkg/scalers/postgresql_scaler.go constructs libpq-style connection strings from tenant-controlled host, port, userName, dbName, sslmode, and password values, while escapePostgreConnectionParameter() only quotes values containing a literal space. Tabs, newlines, carriage returns, form feeds, vertical tabs, quotes, and backslashes can therefore create additional key-value tokens when pgx parses the string. An attacker able to create or modify a TriggerAuthentication or ScaledObject can inject host or sslmode parameters, redirect the database connection to an attacker-controlled server, expose credentials, or disable intended TLS protection. This issue is fixed in version 2.20.0."}, {"lang": "es", "value": "KEDA es un componente de autoescalado basado en eventos y en Kubernetes. Antes de la versi\u00f3n 2.20.0, pkg/scalers/postgresql_scaler.go construye cadenas de conexi\u00f3n estilo libpq a partir de valores controlados por el inquilino para host, puerto, userName, dbName, sslmode y password, mientras que escapePostgreConnectionParameter() solo entrecomilla los valores que contienen un espacio literal. Las tabulaciones, saltos de l\u00ednea, retornos de carro, avances de p\u00e1gina, tabulaciones verticales, comillas y barras invertidas pueden, por lo tanto, crear tokens clave-valor adicionales cuando pgx analiza la cadena. Un atacante capaz de crear o modificar un TriggerAuthentication o un ScaledObject puede inyectar par\u00e1metros de host o sslmode, redirigir la conexi\u00f3n de la base de datos a un servidor controlado por el atacante, exponer credenciales o deshabilitar la protecci\u00f3n TLS prevista.
