Htmlreplace is to replace the contents of all HTML files or selected HTML files in a directory with the contents of the specified file, which is especially useful for the same contents of a page, such as a menu bar. This substitution function allows for some security filtering of user input, preventing users from committing unsafe code. $rptype = 0 means replacing HTML tags only//$rptype = 1 means replac

By convention, I wrote it above: maybe in the process of learning Android, everyone will learn a lot of basic knowledge like me, and a lot of knowledge points can also be said 123, however, these isolated points are too fragmented after all. Therefore, I want to take the most classic mobile security guard project as an example from today and exercise on my own. I also want to communicate with you, I hope everyone can give insights and make progress to

Code injection A particularly dangerous situation is when you try to use contaminated data as a leading part of a dynamic inclusion: In this scenario, the attacker can manipulate not just the file name, but also the contained resources.
