Is PHP a vulnerability?
The remote code execution PHP vulnerability allows attackers to upload malicious code to your website and remotely execute it. It happens when a bug in the PHP application accepts user inputs and misinterprets them as PHP code. It allows an attacker to create a new file that grants them complete access to your website.
Is PHP is insecure?
Since PHP is so popular, PHP security is essential and the number of vulnerable PHP applications is large. Most PHP web applications share parts of code or scripts with other web applications. If the shared piece of code is found to be vulnerable, all the applications that are using it are also vulnerable.
Why does PHP have so many vulnerabilities?
And indeed, as recent research demonstrates, many PHP applications suffer from vulnerabilities due to bad design and lackluster understanding of basic security practices required to secure a web application.
