I have uploaded a simple PHP shell onto a server, but I get one of the following error messages when I am trying to execute a code:
Warning: shell_exec() Unable to execute 'ls' in .... on line 2
Warning: shell_exec() Unable to fork [ls] in ... on line
I think that there are some folder privileges that does not allow me to execute my code. How can I evade it?
Since that "open_basedir restriction in effect", is there a way to execute my shell?
