Problem:  Linux stores your passwords in plaintext
          See proof of concept exploit below

Fix:      rm -rf /dev/kmem


Demonstration:

- ---flic---
bash$ ./passcheck.sh secret
checkpass v1.5
Proves that kmem leakes your passwords
Needs to be run as root
By etah^etihw aka peter-pan

Checking for password 'secret'
Binary file /proc/kcore matches
- -flac-

OMG!!!! it matches!!!
Please don't tell anyone my root password because
I cant change it because i deleted the passwd program
because i thougt that it is vulnerable but I
think it was not vulnerable but i cant get it because
I have to port undel.exe to lunix first.

Here is the 0-DAY exploit!
Please do not abuse!!!

- ---click---
#!/bin/bash

# POC exploit
# shows kmem is a fscking leaker!

echo "checkpass v1.5";
echo "proves that kmem leakes your passwords";
echo "needs to be run as root";
echo "by etah^etihw";
echo "             ";

echo "checking for password '$1'";
grep $1 /proc/kcore
- ---clack---

(do not forget to make 'chmod +x passcheck.sh'!!)


Greets:
zisss (you are the man bro!!)
drater (mad resopectz to yu0!!)
verb (wuz up? your a.t. owns me ass!!)
jchrist (your dad > *)
