PHP local file inclusion vulnerability environment build and use 0x00 introduction
Php local files contain vulnerability-related knowledge. on Wooyun, there was a related article. lfi with phpinfo was first proposed by Daniel abroad. you can refer to the following two articles. The principle of exploits is to use php post to upload files to generate temporary files. phpinfo () reads the path and name of the temporary files. a backdoor is generated by

I. background and descriptionVelocity is a java-based template engine that allows anyone to reference objects defined by java code simply using the template language. We know that the more powerful the rendering layer language with rich functions (in a sense, PHP can also be classified as a rendering layer Language), the more security problems it brings.Some people think that velocity cannot write java code like jsp, And it is strictly isolated by mvc, so it is quite safe.

PHP local file contains knowledge of the vulnerability, dark clouds early on the corresponding article, Lfi with Phpinfo first by foreign Daniel, can refer to the following two articles. The use of the principle is to use the PHP post upload file to generate temporary files, phpinfo () read the temporary file path and name, the local containing the vulnerability generated 1 words back door.

This is called a remote file that contains RFI. Obviously, RFI is more powerful, but the premise for implementing RFI is to ensure that the two parameters allow_url_fopen and allow_url_include in PHP are enabled. These two parameters are disabled by default, therefore, most RFI cannot be executed. It
