From ice source s blog I remember yesterday I intruded into a website named PHP + MYSQL. The main site cannot go in! OK. Next to the next day, there is a next station. Of course, I think of Elevation of Privilege. I have carefully read the following permissions: Only one E:/MYSQL5 and the website directory [supports PHP] can be viewed. None of the other permissions are available. [I may not find a dish] There is no way to think of my SQL data storage

There seems to be none below x. I haven't found it and haven't checked the function manual. I just wrote something in my own experience. 4. Let's take a look at the function manual tomorrow for another expe

Tags: mysql databaseOne day accidentally changed the root of the permissions to the smallest (only login, nothing can do), this may be urgent to me. Heavy-loaded words too troublesome, and there are many users, one after another do not know when.Then I thought of a way, the current server to stop the MySQL service, the MySQL data directory under the MySQL directory renamed to Mysql_old, to another server under the MySQL directory/data/mysql directory

After the phone has root privileges, due to some of its own properties and the impact of the system environment, the following operations may be a certain risk, please do it carefully. Once your phone has root privileges, you can get more features from app Treasure, as follows: 1, uninstall the System program: After you get root permissions, you can uninstall

We recommend a very good Linux kernel system with great learning value. Here I will mainly explain the application of the Linux kernel system, including introduction to the knowledge of the Linux kernel system. When using the Linux kernel, if you use ls-la/, you will find that there are many directories under/, such as etc, usr, var, and bin, in these directories, let's look at them and find that there are also many directories or files. The Linux File System looks like a tree structure, so we c

After webbackdoor itself is root (potentially poor) or a vulnerability overflows to obtain the highest permissions, it can bring us many benefits if we can get the root password. I checked the methods of my predecessors. One is to cheat su to record the password, and the other is to replace sshd. Let's look at the code to cheat su to record the password! First look at the first, kpr-fakesu.c V0.9beta167Fuck
