Detailsinfo

A vulnerability classified as problematic was found in pow_assent (affected version not known). This vulnerability affects some unknown functionality of the component PowAssent.Phoenix.AuthorizationController. The manipulation with an unknown input leads to a resource consumption vulnerability. The CWE definition for the vulnerability is CWE-400. The product does not properly control the allocation and maintenance of a limited resource, thereby enabling an actor to influence the amount of resources consumed, eventually leading to the exhaustion of available resources. As an impact it is known to affect availability. CVE summarizes:

The use of `String.to_atom/1` in PowAssent is susceptible to denial of service attacks. In `PowAssent.Phoenix.AuthorizationController` a value is fetched from the user provided params, and `String.to_atom/1` is used to convert the binary value to an atom so it can be used to fetch the provider configuration value. This is unsafe as it is user provided data, and can be used to fill up the whole atom table of ~1M which will cause the app to crash.

The weakness was published 11/25/2019 (GitHub Repository). The advisory is shared for download at github.com. This vulnerability was named CVE-2019-16764 since 09/24/2019.
