  File Inclusion
File Inclusion enables an attacker to inject custom files into PHP's file loading mechanism, either explicitly passed to include, or for example via PHP's auto-loading mechanism.
  Regex Injection
Regex Injection enables an attacker to execute arbitrary code in your PHP process.
  SQL Injection
SQL Injection enables an attacker to execute arbitrary SQL code on your database server gaining access to user data, or manipulating user data.
  Response Splitting
Response Splitting can be used to send arbitrary responses.
  File Manipulation
File Manipulation enables an attacker to write custom data to files. This potentially leads to injection of arbitrary code on the server.
  Object Injection
Object Injection enables an attacker to inject an object into PHP code, and can lead to arbitrary code execution, file exposure, or file manipulation attacks.
  File Exposure
File Exposure allows an attacker to gain access to local files that he should not be able to access. These files can for example include database credentials, or other configuration files.
  XML Injection
XML Injection enables an attacker to read files on your local filesystem including configuration files, or can be abused to freeze your web-server process.
  Code Injection
Code Injection enables an attacker to execute arbitrary code on the server.
  Variable Injection
Variable Injection enables an attacker to overwrite program variables with custom data, and can lead to further vulnerabilities.
  XPath Injection
XPath Injection enables an attacker to modify the parts of XML document that are read. If that XML document is for example used for authentication, this can lead to further vulnerabilities similar to SQL Injection.
  Other Vulnerability
This category comprises other attack vectors such as manipulating the PHP runtime, loading custom extensions, freezing the runtime, or similar.
  Command Injection
Command Injection enables an attacker to inject a shell command that is execute with the privileges of the web-server. This can be used to expose sensitive data, or gain access of your server.
  LDAP Injection
LDAP Injection enables an attacker to inject LDAP statements potentially granting permission to run unauthorized queries, or modify content inside the LDAP tree.
  Cross-Site Scripting
Cross-Site Scripting enables an attacker to inject code into the response of a web-request that is viewed by other users. It can for example be used to bypass access controls, or even to take over other users' accounts.
  Header Injection

Security Best Practice introduced by
It is not recommended to use PHP's short opening tag <?, better use <?php, or <?= in case of outputting.

Short opening tags are disabled in PHP?s default configuration. In such a case, all content of this file is output verbatim to the browser without being parsed, or executed.

As a precaution to avoid these problems better use the long opening tag <?php.

It seems like you do not handle an error condition for closedir(). This can introduce security issues, and is generally not recommended.
                                                                                                                                       (

If you suppress an error, we recommend checking for the error condition explicitly:


// For example instead of
@mkdir($dir);

// Better use
if (@mkdir($dir) === false) {
    throw new \RuntimeException('The directory '.$dir.' could not be created.');
}

It seems like $dh can also be of type false; however, parameter $dir_handle of closedir() does only seem to accept resource, maybe add an additional type check?

Are you sure the usage of closedir($dh) is correct as it seems to always return null.
                                                                                                

                    
                                            

                            

                            

                                
                                    
                                
                            


                            
This check looks for function or method calls that always return null and whose
return value is used.


class A
{
    function getObject()
    {
        return null;
    }

}

$a = new A();
if ($a->getObject()) {





The method getObject() can return nothing but null, so it makes no sense
to use the return value.


The reason is most likely that a function or method is imcomplete or has been
reduced for debug purposes.

It is not recommended to use PHP's closing tag ?> in files other than templates.
                                            

                    
                                            

                            

                            

                                
                                    
                                
                            


                            
Using a closing tag in PHP files that only contain PHP code is not recommended
as you might accidentally add whitespace after the closing tag which would then
be output by PHP. This can cause severe problems, for example headers cannot be
sent anymore.


A simple precaution is to leave off the closing tag as it is not required, and
it also has no negative effects whatsoever.
