dalek-browser-ie-canary is Internet Explorer bindings for DalekJS. dalek-browser-ie-canary downloads binary resources over HTTP, which leaves it vulnerable to MITM attacks. It may be possible to cause remote code execution (RCE) by swapping out the requested binary with an attacker controlled binary if the attacker is on the network or positioned in between the user and the remote server.
dalek-browser-ie-canary is Internet Explorer bindings for DalekJS. dalek-browser-ie-canary downloads binary resources over HTTP, which leaves it vulnerable to MITM attacks. It may be possible to cause remote code execution (RCE) by swapping out the requested binary with an attacker controlled binary if the attacker is on the network or positioned in between the user and the remote server.
Affected versions of `dalek-browser-ie-canary` insecurely download an executable over an unencrypted HTTP connection. In scenarios where an attacker has a privileged network position, it is possible to intercept the response and replace the executable with a malicious one, resulting in code execution on the system running `dalek-browser-ie-canary`. ## Recommendation No patch is currently available for this vulnerability, and the package author has marked the package as deprecated. The best mitigation is currently to avoid using this package, using a different package if available. Alternatively, the risk of exploitation can be reduced by ensuring that this package is not installed while connected to a public network. If the package is installed on a private network, the only people who can exploit this vulnerability are those who have compromised your network or those who have privileged access to your ISP, such as Nation State Actors or Rogue ISP Employees.

dalek-browser-ie-canary proporciona enlaces de Internet Explorer para DalekJS. dalek-browser-ie-canary descarga recursos binarios por HTTP, lo que lo deja vulnerable a ataques MITM. Podría ser posible provocar la ejecución remota de código (RCE) cambiando el binario solicitado por otro controlado por el atacante si éste están en la red o posicionado entre el usuario y el servidor remoto.
