How to Fix GHSA-xffp-6w68-4775

To remediate this vulnerability, upgrade all affected Zendframework/zendframework dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

zendframework/zendframework fixed: 2.2.5 
Upgrade zendframework/zendframework to 2.2.5
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for zendframework/zendframework

How to Check if You Are Affected

To determine whether your application is affected by GHSA-xffp-6w68-4775, inspect your project dependencies for Zendframework/zendframework:

inspect dependencies for zendframework/zendframework

Analyze the terminal output to locate any version of Zendframework/zendframework in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.2.5), 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 Zendframework/zendframework, 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 `Zend\Http\PhpEnvironment\RemoteAddress` class provides features around detecting the internet protocol (IP) address for an incoming proxied request via the X-Forwarded-For header, taking into account a provided list of trusted proxy server IPs. Prior to 2.2.5, the class was not taking into account whether or not the IP address contained in PHP's `$_SERVER['REMOTE_ADDR']` was in the trusted proxy server list. The IETF draft specification indicates that if `$_SERVER['REMOTE_ADDR']` is not a trusted proxy, it must be considered the originating IP address, and the value of X-Forwarded-For must be disregarded.
