CVE-2017-16035
Because of this behavior an attacker with the ability to man-in-the-middle a developer or system performing a package installation could compromise the integrity of the installation.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.72%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
The hubl-server module is a wrapper for the HubL Development Server. During installation hubl-server downloads a set of dependencies from api.hubapi.com. It appears in the code that these files are downloaded over HTTPS however the api.hubapi.com endpoint redirects to a HTTP url. Because of this behavior an attacker with the ability to man-in-the-middle a developer or system performing a package installation could compromise the integrity of the installation.
