Summary0004572: Update tools.kali.org : linux-exploit-suggester.sh - Updated/Forked Version
Description

I'm aware that Kali already contains Linux_Exploit_Suggester (https://tools.kali.org/exploitation-tools/linux-exploit-suggester). Unfortunately AFAIK this tool is not maintained anymore and is out of date (last added exploits are from 2014).

linux-exploit-suggester.sh (https://github.com/mzet-/linux-exploit-suggester) is up to date and regularly updated. It contains all the exploits that are present in Linux_Exploit_Suggester (excluding those that are applicable solely for kernels 2.4 and older) plus all the latest (as of early 2018) publicly known Linux kernel exploits.

linux-exploit-suggester.sh is inspired on Linux_Exploit_Suggester so basic philosophy and use case is the same. However it also comes with some additional features:

  • when run directly on examined machine it can perform some additional checks (like kernel's CONFIG_* and/or sysctl entries) to rule out exploits that won't be applicable
  • most exploits contain additional info (Tags) about which distro they were succesfully run
  • tool also contains exploits (that leads to LPE) for userspace software
  • other minor features

Currently linux-exploit-suggester.sh contains:

For more details please see README.md at https://github.com/mzet-/linux-exploit-suggester.

Thanks for consideration.

GPLv3

  • [Description] - What is the tool about? What does it do?

linux-exploit-suggester.sh tool is meant to assist security analyst in identifying possible privilege escalation attack vectors on target Linux machine by suggesting possible exploits.

  • [Dependencies] - What is needed for the tool to work?

Tool is implemented as a single Bash script. It requires Bash in version >= 4.0 in order to run.

  • [Similar tools] - What other tools are out there?

Similar to (and inspired by) https://github.com/InteliSecureLabs/Linux_Exploit_Suggester.

  • [Activity] - When did the project start? Is is still actively being deployed?

Project has started on 6 Oct 2016. Yes, it is actively being developed and maintained.

  • [How to install] - How do you compile it?
    --- Note, using source code to acquire (e.g. git clone/svn checkout) can't be
    used - Also downloading from the head. Please use a "tag" or "release" version.

No compilation is involved - the tool is implemented as a single Bash script.

After downloading the tool (in version 0.9) from https://github.com/mzet-/linux-exploit-suggester/archive/v0.9.tar.gz the tool is ready to run.

  • [How to use] - What are some basic commands/functions to demonstrate it?

Basic usage (see more examples at: https://github.com/mzet-/linux-exploit-suggester#usage):

checks for possible kernel space (and for Ubuntu, Debian, RHEL/CentOS, Fedora distros also for user space) exploits based on kernel (package) version and other settings like (kernels CONFIG_* compile time settings and sysctl entries):
$ ./linux-exploit-suggester.sh

enumerates kernel and hardware protection mechanisms (KASLR, SMEP, SMAP, etc.):
$ ./linux-exploit-suggester.sh --checksec

lists possible exploits for Linux kernel in version 3.3.*:
$ ./linux-exploit-suggester.sh -k 3.3

checks for possible kernel space and user space exploits based on output from given 'uname -a' command output and based on provided package file listing (output from 'dpkg -l' or 'rpm -qa' commands):
$ ./linux-exploit-suggester.sh --uname <output_fromuname-a_cmd> --pkglist-file <pkg_listing_file>

to see help:
$ ./linux-exploit-suggester.sh -h

Please reconsider adding LES tool to the Kali. The tool has matured, is up to date, has excellent '--checksec' functionality in summary it is much more then its predecessor (https://tools.kali.org/exploitation-tools/linux-exploit-suggester) I believe. See detailed paper (in a form of blog post) here: https://mzet-.github.io/2019/05/10/les-paper.html for details about the tool inner workings and novel techniques it uses to limit false positives when generating list of candidate exploits.

Please see below for (updated) information about the tool:

Thanks for consideration.

The old one doesn't exists any more ~ https://github.com/PenturaLabs?tab=repositories

I would recommend we switch

If we're going to add it to Kali, can we queue it for ver. 2020.2 (https://bugs.kali.org/changelog_page.php?version_id=25)?

Site https://tools.kali.org/exploitation-tools/linux-exploit-suggester still describes the all version of the tool. It should be updated as well.

@kali-team,

Is there anything I can help with with updating the https://tools.kali.org/exploitation-tools/linux-exploit-suggester site? This is obviously out of date - the new tool was added to Kali in May 2020, we should sync up the https://tools.kali.org site to reflect this. Here's the proposed draft of the page:

Tool's description:

LES tool is designed to assist in detecting security deficiencies for a given Linux kernel/Linux-based machine. It provides following functionality:

  • Assessing Linux-based machine exposure on publicly known privilege escalation exploits
  • Verifying state of kernel hardening security measures

Source: https://github.com/mzet-/linux-exploit-suggester

Author: mzet
License: GPLv3

Tools included in the linux-exploit-suggester package

(no modifications are needed here I believe)

linux-exploit-suggester Usage Example

Assess an exposure of the Linux box on publicly known privilege escalation exploits:

linux-exploit-suggester

Show state of Linux kernel security features on the Linux box:

linux-exploit-suggester --checksec

Assess an exposure of Linux kernel on publicly known exploits based on the provided 'uname' string (i.e. output of uname -a command):

linux-exploit-suggester --uname &lt;uname-string>
