PHP Security Vulnerability: Help with Analysis and Remediation for Websites and Applications

Need help updating PHP?

Has your hosting provider asked you to update PHP, but you are unsure what to do? Is your previous webmaster no longer available? Or does your company rely on an older PHP application that nobody maintains anymore? We assess your existing environment and explain the steps needed.

Call us: +41 44 805 20 70 or email us. First come, first served.

Is your website or application affected?

Many business websites, online shops and business applications run on PHP. Under certain conditions, the current vulnerabilities could allow attackers to execute their own code on the server. Security updates are available.

Just because your website still works does not mean the vulnerabilities have been fixed. Some hosting providers handle updates centrally. For privately managed servers or older applications, updates often need to be carried out individually.

You do not need to know your PHP version. To get started, simply send us a brief description of your situation and, if known, your website address and hosting provider.

Let us handle your PHP update

We assess your PHP environment and the available update options. We then agree on the next steps with you:

• Analysis: Identify the environment in use and the updates required.

• Preparation: Check backups and recovery options.

• Implementation: Install security updates and make any necessary adjustments.

• Verification: Test the agreed functionality after the update.

If additional work is required, we discuss the scope and costs with you before proceeding.

Support for older PHP applications without a maintainer

We also support custom-built customer portals, internal tools and business applications whose original developer is no longer available.

We review the existing code and server environment to determine whether a security update is sufficient or whether the application needs adjustments. You receive a clear assessment to help you decide how to proceed.

Based in Zurich, providing remote support throughout Switzerland

SampleZone GmbH is based in the Zurich area. We can carry out the assessment and update entirely through secure remote access, supporting businesses throughout Switzerland without an on-site visit.

We require suitable access with the necessary permissions. You, your hosting provider or your existing IT service provider supply this access. We explain what is needed and how to share it securely.

How much does support cost?

Our express service starts at CHF 490 and includes the first two hours of work.

During this time, we assess your environment and carry out the updates possible within that timeframe. Working access with sufficient permissions must be provided in advance.

The total work required depends on the condition of your website or application. Additional work is agreed in advance and billed based on time spent. Extensive modifications and the investigation of a suspected attack are agreed separately.
