Whether you’re a web developer or a site owner, chances are you’ve worked with PHP—a widely used scripting language for web development. Major sites like Facebook, Wikipedia, and WordPress rely on PHP for back-end functionality. However, over 55% of PHP sites are still running outdated versions, making them vulnerable to attacks.
A comprehensive PHP penetration test can uncover hidden security weaknesses that could compromise your site. This guide will equip you with the knowledge and tools to refine practical PHP penetration testing procedures, safeguarding your website from potential threats.
The Need for PHP Penetration Test & Security Audits
Vulnerability Identification
A regular PHP audit allows you to adopt a proactive approach to maintaining the security posture of PHP sites, especially those running on older versions. It can help identify critical vulnerabilities like Remote Code Execution, SQL injection, or even simple misconfigurations.
Regulatory Compliance
Industries require compliance with security standards like GDPR, SOC 2, or HIPAA. Regular auditing helps your PHP applications meet these standards and avoid any legal penalties, as all these compliances require regular auditing.
Improved Performance
Security audits help your PHP applications optimize their performance by identifying and mitigating inefficient code and misconfigurations that could impact their reliability and integrity.

How To Carry Out a Complete PHP Penetration Test?
Information Gathering
The first step in the penetration test involves gathering information about the target PHP application. This stage allows testers to uncover entry points and potential weaknesses. Tools like Nmap, whois, wappalyzer, netcraft etc. can be used to gain a vast amount of information about the target.
Nmap is a scanning tool used to identify open ports and services used to run vulnerability scripts. Its version detection capabilities and scriptable interaction through the NSE help security professionals automate tasks, improve scan capabilities, and create custom scripts for specific situations.
Vulnerability Scanning
The next step in PHP penetration testing is to scan the applications for potential vulnerabilities using automated web server scammers. This step identifies potential security threats and weak endpoints that could lead to full-scale exploitation.
Tools like ZAP, OpenVAS, or Nikto can be used to perform complete vulnerability scanning. Nikto is a web server scanner that tests websites for security risks and vulnerabilities. OpenVAS performs an in-depth comparison of the site with a vulnerability database, providing a comprehensive overview of the security risk in the target site.
Exploitation
After gathering the information and scanning for weaknesses, the next step is to manually exploit these potential threats to their full extent and determine the actual damage that can be caused to the application, data, or organization.
The pentest can include the following tests depending on the features of the applications:
- Testing Misconfigurations: Test the PHP application for misconfigurations, such as default passwords, accessible directories, and server-level misconfigurations.
- Testing Authentication: Ensuring that the authentication is set up properly and the overall mechanism is secure allows for preventing issues like privilege escalation.
- Testing Authorization: Testing the access control rules and mechanisms helps you maintain the confidentiality and integrity of the user data and prevent unauthorized access and misuse.
- Testing Session Management: Testing if session cookies are appropriately implemented and are secure to prevent issues like session hijacking or session fixation from occurring.
- Testing Business Logic: Testing the logic of the application to ensure that any process or feature does not misbehave and bypass the security.
- Testing File Uploads: Testing the file upload rules and mechanism whether it allows uploading of malicious files causing vulnerabilities like code execution.
Tools like Metasploit can be exploited, as they automate attack simulation to execute specific payloads for a more targeted execution. Moreover, tools like BurpSuite can be used to manually test the site and its APIs to exploit weaknesses in the website’s application logic.

I own a website which is php based and I want to know if there are any vulnerabilities that can give access to hackers to hack my site. Is there any way I can do that?
PHP is the backbone of almost every popular CMS today. Thanks to its simplicity and license-free nature, PHP is the preferred choice for dynamic website development. However, due to poor coding standards, compromising PHP sites has become relatively easy. The internet is full of help threads where users complain about custom PHP website hacked or PHP website redirects hack. This has led to a lot of negative publicity for PHP itself which is nowhere to be blamed for this.

Is csrf is also a part of hacking? What can be done here to secure from happening this?
Thanks for responding to the article. A CSRF attack involves a malicious website sending a request to a web application via another formerly authenticated website. This allows the attacker to dodge authentication procedures by impersonating the victim using his/her credentials and perform malicious activity or financial transactions. Hot targets for such attacks are online banking services, social media applications and web interfaces for network devices.
