A buffer overflow condition exists in some versions of /usr/sbin/ping under AIX. Given that ping is SUID root, this overflow allows malicious users to gain root from it.

 *
 *   /usr/sbin/ping exploit (kinda' coded) by BeastMaster V
 *
 *   CREDITS: this is simpy a modified version of an exploit
 *   posted by Georgi Guninski (guninski@hotmail.com)
 *
 *   This will give a #rootshell# by overwriting a buffer
 *   in /usr/sbin/ping while ping is setuid to root.
 *   This exploit is designed for AIX 4.x on PPC platform.
 *
 *
 *   USAGE:
 *            $ cc -o foo -g aix_ping.c
 *            $ ./foo 5100
 *            #
 *
 *
 *   HINT: Try giving ranges from 5090 through 5500
 *
 *   DISCLAIMER: use this program in a responsible manner.

IBM AIX ping Command Line Argument Overflow
Local Access Required Input Manipulation
Loss of Integrity Solution Unknown
Exploit Public

- 漏洞描述

A local overflow exists in AIX ping. The AIX ping fails to check command line arguments length resulting in a buffer overflow. With a specially crafted request, an attacker can execute arbitrary commands resulting in a loss of integrity.
