Descriptions

Angular Expressions before version 1.0.1 has a remote code execution vulnerability if you call expressions.compile(userControlledInput) where userControlledInput is text that comes from user input. If running angular-expressions in the browser, an attacker could run any browser script when the application code calls expressions.compile(userControlledInput). If running angular-expressions on the server, an attacker could run any Javascript expression, thus gaining Remote Code Execution.

Angular Expressions versiones anteriores a 1.0.1, presenta una vulnerabilidad de ejecución de código remota si llama a expressions.compile(userControlledInput) donde userControlledInput es texto que proviene desde la entrada del usuario. Si ejecuta expresiones angulares en el navegador, un atacante podría ejecutar cualquier script del navegador cuando el código de la aplicación llame a expressions.compile(userControlledInput). Si ejecuta expresiones angulares en el servidor, un atacante podría ejecutar cualquier expresión Javascript, consiguiendo así una Ejecución Remota de Código.
