    Linuxprivchcker needs python on the system which usually is there. If not, one could do the similar thing using bash. Will have to serach in gethub site

    python -c 'import pty; pty.spawn("/bin/sh")'

    ……emulate bash session from an hacked session so one can enter root pwd. If you try w/o it, you may get a message "su: must be run from a terminal"

  • Escaping restricted shell

    If I can run the command echo, I can easily “escape” and bypass the limited shell by using the command echo os.system('/bin/bash')

    1. The following python script appeared to create the above string in cryptedpass.txt: /encode & decode pwd
    sh-4.1$ cat cryptpass.py
    cat cryptpass.py
    #Enhanced with thanks to Dinesh Singh Sikawar @LinkedIn
    import base64,codecs,sys
    def encodeString(str):
        base64string= base64.b64encode(str)
        return codecs.encode(base64string[::-1], 'rot13')
    cryptoResult=encodeString(sys.argv[1])
    print cryptoResult
    The above script was modified on the attacking machine to decode the string:
    #Enhanced with thanks to Dinesh Singh Sikawar @LinkedIn
    import base64,codecs,sys
    def encodeString(str):
        base64string= base64.b64encode(str)
        return codecs.encode(base64string[::-1], 'rot13')
    def decodeString(str):
        string = str[::-1]
        string = string.encode("rot13")
        return base64.b64decode(string)
    print decodeString(sys.argv[1])
    String successfully decoded:
    [root:~]# python reverse.py "=RFn0AKnlMHMPIzpyuTI0ITG"
