Gateforth Systems: PHP2Shell Codebase Remediation CVE-2026-109618 & CVE-2026-109619

Rigorous, fixed-outcome codebase remediation for critical unauthenticated remote code execution vulnerabilities. Prepare your legacy PHP application for a sever upgrade without long-term contracts or synchronous meetings.

We understand that a CVSS 9.2 vulnerability represents an immediate threat to your business operations. Gateforth Systems provides a structural, engineered resolution for PHP2Shell compatibility blockers. We audit your codebase, identify the necessary code changes, and provide a fixed-price intervention to ensure your application can run safely on a secure PHP version.

Book a Diagnostic Audit

A Fixed-Outcome Process

To ensure precise cost control and structural integrity, our remediation process is divided into a standalone diagnostic phase followed by a fixed-price intervention, delivered entirely asynchronously.

01 Diagnose

Book the PHP2Shell Audit online and provide secure repository access. We conduct a targeted static analysis to locate the vulnerability footprints and structural blockers.

02 Quote

You receive a Diagnostic Audit Report identifying the specific code incompatibilities preventing a secure PHP upgrade, alongside a fixed-price, fixed-outcome quote for resolving them.

03 Execute

Upon approval, we deliver the remediation asynchronously. You receive a verified codebase and a targeted report confirming the application is ready for a server upgrade.

Service Specification

PHP2Shell Audit

The mandatory baseline engagement. We map the true state of your legacy codebase to scope the precise structural changes required to prepare your application for a secure server environment.

  • Deliverable: The Diagnostic Report, including a fixed-price proposal for the required structural remediation and PHP compatibility upgrade.
  • Timeline: 10 business days, subject to current lead times.
  • Fixed Fee: £2,950 + VAT

Targeted Remediation

Following the audit, we implement the structural code changes required to make your application fully compatible with a secure version of PHP. This removes the technical blockers preventing your hosting provider from upgrading your server to close the PHP2Shell vulnerability.

  • Fixed Pricing: A strict fixed fee calculated directly from the audit findings, ensuring absolute cost control.
  • Verified Delivery: We deliver the updated code directly to your repository, ready for your team or agency to deploy.
  • Compatibility Confirmation: The delivery includes a final report confirming the codebase passes all targeted PHP version checks, authorising your infrastructure provider to safely execute the server upgrade.

Beyond the Immediate Threat

A critical vulnerability is frequently a symptom of broader technical debt. Operating unsupported legacy software inherently carries compounding risk.

Our remediation process does more than apply a temporary patch. By structuring the resolution as a formal compatibility upgrade, our objective is to transform a fragile, unsupported codebase into a stable asset that your next internal hire or agency can manage with confidence.

Operational Standards

Asynchronous & Remote

Prioritising written communication and eliminating meetings to maximise engineering focus.

Zero Onboarding

A secure, hands-off process. Simply provide read-only repository access, and we begin the audit.

Strict Confidentiality

All diagnostic and remediation work is conducted under a standard Non-Disclosure Agreement.

Outside IR35

Structured as a specialist B2B service contract for clear compliance and zero administrative burden.
