How to Fix CVE-2017-11675

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

zencart/zencart fixed: Latest secure release 
Upgrade zencart/zencart to Latest secure release
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 zencart/zencart

How to Check if You Are Affected

To determine whether your application is affected by CVE-2017-11675, inspect your project dependencies for Zencart/zencart:

inspect dependencies for zencart/zencart

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-94: Improper Control of Generation of Code ('Code Injection'), where the product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. In Zencart/zencart, 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 traverseStrictSanitize function in admin_dir/includes/classes/AdminRequestSanitizer.php in ZenCart 1.5.5e mishandles key strings, which allows remote authenticated users to execute arbitrary PHP code by placing that code into an invalid array index of the admin_name array parameter to admin_dir/login.php, if there is an export of an error-log entry for that invalid array index.
