inspect dependencies for phoenix

How to Check if You Are Affected

To determine whether your application is affected by CVE-2017-1000163, inspect your project dependencies for Phoenix:

inspect dependencies for phoenix

Analyze the terminal output to locate any version of Phoenix in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.0.6), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-601: URL Redirection to Untrusted Site ('Open Redirect'), where the web application accepts a user-controlled input that specifies a link to an external site, and uses that link in a redirect. In Phoenix, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

The Phoenix team designed `Phoenix.Controller.redirect/2` to protect against redirects allowing user input to redirect to an external URL where your application code otherwise assumes a local path redirect. This is why the `:to` option is used for “local” URL redirects and why you must pass the `:external` option to intentionally allow external URLs to be redirected to. It has been disclosed that carefully crafted user input may be treated by some browsers as an external URL. An attacker can use this vulnerability to aid in social engineering attacks. The most common use would be to create highly believable phishing attacks. For example, the following user input would pass local URL validation, but be treated by Chrome and Firefox as external URLs: `http://localhost:4000/?redirect=/\nexample.com` Not all browsers are affected, but latest Chrome and Firefox will issue a get request for `example.com` and successfully redirect externally
