Security of executing a command from php
- by Nicolò Martini
I'm writing a web application in which i use several thirdy party commands calling them with the exec function in PHP (for example, I render Latex formulas through a command-line program).
My question is: what are the security issues of executing external command-line programs in php? What I have to be aware of? Can you give me a list of points to check?
Thanks in advance.
