How to fix CWE-601: URL Redirection to Untrusted Site ('Open Redirect') in node js ?

The following code got the CWE-601 issue in veracode scan report, can anyone suggest how to fix in node js?

 

const route = `/cc/${ci}/activity/${daid}`;

ctx.redirect(route);


  • Hi @SKavitapu407634 (Community Member)​ ,

     

    Veracode Static Analysis reports CWE 601 when it can see that dynamic data from outside of the application is going into the URL.

    The concern being that if an attacker can influence this data they may be able to change the URL your users are sent to.

    Veracode Static Analysis will only automatically close this flaw if you are able to use only hardcoded or numeric data in the URL.

    If you have identifiers that are numeric you may want to cast them to a Number before including them in the URL.

     

    If this is not possible we recommend URL encoding any path or query variables (and optionally adding validation), you can then document this for manual review using a mitigation proposal ( https://docs.veracode.com/r/improve_mitigation ) and request someone from your organizations security team to review.

    Please note that URL encoding is valid only for path and query data. URL encoding as applied to hosts does not add any validation and for dynamic hosts we would recommend allow-list validation.

     

    Thank you,

    Boy Baukema

    An http parameter may contain a URL value and could cause the web application to redirect the request to the specified URL. By modifying the URL value to a malicious site, an attacker may successfully launch a phishing scam and steal user credentials. Because the server name in the modified link is identical to the original site, phishing attempts have a more trustworthy appearance.
