CVE-2020-9297

https://notcve.org/view.php?id=CVE-2020-9297

Netflix Titus, all versions prior to version v0.1.1-rc.274, uses Java Bean Validation (JSR 380) custom constraint validators. When building custom constraint violation error messages, different types of interpolation are supported, including Java EL expressions. If an attacker can inject arbitrary data in the error message template being passed to ConstraintValidatorContext.buildConstraintViolationWithTemplate() argument, they will be able to run arbitrary Java code. Netflix Titus, todas las versiones anteriores a la versión v0.1.1-rc.274, utiliza validadores de restricción personalizados de Java Bean Validation (JSR 380). Cuando se crean mensajes de error de violación de restricciones personalizadas, diferentes tipos de interpolación son compatibles, incluidas las expresiones Java EL. • https://github.com/Netflix/security-bulletins/blob/master/advisories/nflx-2020-002.md • CWE-917: Improper Neutralization of Special Elements used in an Expression Language Statement ('Expression Language Injection') •
