How to Fix CVE-2023-24676

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

processwire/processwire fixed: Latest secure release 
Upgrade processwire/processwire 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 processwire/processwire

How to Check if You Are Affected

To determine whether your application is affected by CVE-2023-24676, inspect your project dependencies for Processwire/processwire:

inspect dependencies for processwire/processwire

Analyze the terminal output to locate any version of Processwire/processwire in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), 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-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 Processwire/processwire, 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

An issue found in Processwire 3.0.210 allows attackers to execute arbitrary code and install a reverse shell via the download_zip_url parameter when installing a new module.
