CVE-2016-10637
Downloads Resources over HTTP in haxe-dev
haxe-dev is a cross-platform toolkit. haxe-dev 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.

GitHub AdvisoriesGHSA-cwp7-92h5-82wx No score
Downloads Resources over HTTP in haxe-dev
Affected versions of haxe-dev 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 haxe-dev.
Recommendation
This package is actively maintained, yet after 2 years, the maintainer has not provided a patch for the vulnerability. This likely means that the maintainer has decided to accept the risk, and this vulnerability will never be patched.
Because of this, 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.
