How to Fix GHSA-mg7h-9qfx-4r83

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: 2.0.5 
Upgrade zendframework/zendframework to 2.0.5
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-mg7h-9qfx-4r83, 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 2.0.5), 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-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection'), where the product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component. 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

`Zend\Session\Validator\RemoteAddr` and `Zend\View\Helper\ServerUrl` were found to be improperly parsing HTTP headers for proxy information, which could potentially allow an attacker to spoof a proxied IP or host name. In `Zend\Session\Validator\RemoteAddr`, if the client is behind a proxy server, the detection of the proxy URL was incorrect, and could lead to invalid results on subsequent lookups. In `Zend\View\Helper\ServerUrl`, if the server lives behind a proxy, the helper would always generate a URL based on the proxy host, regardless of whether or not this was desired; additionally, it did not take into account the proxy port or protocol, if provided.
