ysoserial-modified | repository contains my updates to the well know java

ysoserial-modified is a Java library. ysoserial-modified has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has low support. You can download it from GitHub.

Due how Runtime.getRuntime().exec(String.class) works in java, nested and complex commands where you'll need control pipes or send the output to files (ex: cat /etc/passwd > /tmp/passwd_copy) will not work because the command executed by the exec() method from the Runtime class isn't executed inside of a terminal environment. One possible hack is execute "/bin/sh -c 'command'" but you'll need escape the space charater on the 'command' using ${IFS} or it will not work as expected. For more details about that problem and possible workaround please read this blopost that will go deep on the details. A good solution to fix that problem is pass the arguments to the method Runtime.getRuntime().exec(String[].class) that expects an array of Strings. The best option is execute the following: Runtime.getRuntime().exec(new String[] {"/bin/sh", "-c", "command"}). Passing the arguments that way, java will understand that you're executing the /bin/bash passing the arguments -c and 'command' on the correct way and will execute your command inside of an terminal environment, what will allow you use nested or complex commands (with | or ;) and also control inputs and outputs (with < and >).
