Over 64% of PHP Applications are Running on Unsupported Versions: A Security Time Bomb

Did you know that more than 64% of PHP applications currently in use are running on unsupported versions of the language? This alarming statistic reveals a critical security risk that CEOs, CTOs, and business leaders must not ignore. As of September 2024, PHP remains the server-side programming language for 75.8% of websites where the language could be determined. However, the reality is that many of these websites are using versions that no longer receive security updates, creating an environment ripe for exploitation.

What Does “Unsupported Version” Mean?

An unsupported version refers to a software version that no longer receives patches or updates from its developers, including critical security fixes. Once a version is marked as unsupported, it’s essentially abandoned by its maintainers. While the application may continue to function, the lack of updates means that any newly discovered vulnerabilities remain unpatched, leaving systems exposed to potential threats.

For PHP, this means that applications running on versions such as PHP 7.x (51% of all PHP-based websites) or earlier are in a dangerous position. Official support for PHP 7.x has ended, and these applications no longer receive security updates. Websites still running PHP 5 (13.5%) or even PHP 4 (0.1%) face an even greater risk.

The Security Implications: A Time Bomb Waiting to Explode

Running an unsupported version of PHP is like having a security time bomb on your hands. It’s only a matter of time before unpatched vulnerabilities are discovered and exploited by bad actors. When vulnerabilities remain open for long periods, they become prime targets for hackers, leading to possible:

• Data Breaches: Compromised user data, personal information, and financial records can be stolen, leading to significant privacy violations.
• Website Defacement: Attackers can manipulate your website, damaging your brand and eroding customer trust.
• Ransomware: Hackers can take control of your systems, demanding ransom in exchange for restoring access.

In 2019, 11% of all vulnerabilities listed by the National Vulnerability Database (NVD) were linked to PHP. Though PHP is no less secure than other programming languages, the frequency of vulnerabilities related to outdated PHP versions should serve as a warning for organizations using older releases. Ignoring this could lead to devastating results.

PHP Vulnerabilities: No More Frequent than Other Languages

PHP has often been criticized for security, but the reality is more nuanced. While PHP does account for a significant portion of vulnerabilities, it’s primarily because of its widespread use. In fact, 22 security flaws related to PHP were recorded in 2009—representing only 1% of the total, even though PHP-powered 20% of programs listed at that time. These statistics show that the language itself is not inherently less secure than other programming languages.

The real risk lies not in the language, but in how outdated versions are handled. Using outdated versions of any language—including PHP—opens doors for attackers.

Legal and Financial Risks

The consequences of running unsupported PHP versions extend beyond security risks. Organizations can face:

• Regulatory Fines: Non-compliance with regulations like GDPR or HIPAA due to inadequate data protection can result in heavy fines.
• Financial Losses: The average cost of a data breach is $4.45 million (as of 2023). For smaller businesses, a single breach could be financially crippling.
• Reputation Damage: Customer trust is easily lost when a company suffers a security breach, and rebuilding that trust can take years.

Why Business Leaders Should Act Now

As of September 2024, 51% of websites running PHP still rely on PHP 7.x, despite its end of life (EOL) status. This means that over half of PHP-based web applications are vulnerable to attacks. Ignoring these risks could lead to severe consequences for your organization. CEOs and CTOs must take immediate action to assess their technology infrastructure.

Steps to Take for Better PHP Security:

1. Upgrade to Supported Versions: If your application is running on PHP 7 or earlier, upgrade to a supported version (PHP 8.1 or later). As of now, PHP 8.3 is the latest version and offers enhanced performance and security features.
2. Implement Regular Security Audits: Perform regular audits of your systems to ensure all software versions, including PHP, are up to date.
3. Patch Management: Establish a patch management process to keep your systems updated with the latest security patches.
4. Penetration Testing: Conduct regular penetration testing to identify vulnerabilities before attackers do.
5. Employee Training: Ensure your team is aware of the latest security practices and can identify potential risks before they escalate.

Call to Action: Assess Your Technology Infrastructure Now!

It’s clear that running outdated versions of PHP—or any software—poses a significant risk. CEOs and CTOs, the time to act is now. Your business cannot afford to ignore these vulnerabilities, as the consequences of a breach could be devastating. Ensure your PHP applications are running on supported versions, conduct regular security audits, and prioritize cybersecurity as part of your business continuity strategy.

The longer you wait, the closer you come to setting off that ticking time bomb.
