Scanning WordPress for vulnerabilities


wpscan on github

The quickest way to use it seems to be docker.

docker pull wpscanteam/wpscan
# minimal run
docker run --rm wpscanteam/wpscan -u
# more details options (enumerate vulnerabilities of identify plugins)
docker run --rm wpscanteam/wpscan -u --follow-redirection --update --enumerate

Docker and windows services

All start with a question: can we run Windows software in a Docker container ?
Yes and No… unsurprisingly it depends on the host that executes the container.

A article from Azure CTO that explains MS Azure strategy around Docker:

Making Docker work behind NTLM proxy

Working in a corporate environment, it may come that web access is filtered through a proxy… and even an NTLM one which requiere MS-style authentication.

If you also are lucky enough to run Docker inside a Linux Virtual machine (not natively on Windows), your docker builds or package update operations may fail at first.

You may ease the building and running of docker containers by using an intermediate proxy (cntlm) that will authenticate your and forward your requests against the coprorate proxy, while acting as simpler (unanthenticated) proxy for your doacker daemon or containers.

Build images behind a proxy

My environment:

- Coporate NTLM proxy
- Windows 7 (running cntlm proxy properly configured, listenning to, and NOT in gateway mode)
- Virtual Box 
- Centos 7 
- Docker 

Make docker daemon use the proxy of the Windows host

Not hard but a bit complex:

The first thing to take care of with all these virtualization layers is that means something different for each layer !

The tricky part is to understand that Virtual box creates a specific NIC inside CentOS (address is 10.0.2.x with a default gateway of The IP address is redirected by Virtual Box to the of Windows, on which cntlm proxy is listenning.

Last thing, the daemon needs to be aware of proxy at build time (download an image from web), while apt-get or yum may need to be aware of proxy at build time but also possibly at runtime.

In short, from docker daemon perspective, the proxy is

Docker daemon setup



With content:


Then reload configuration and restart daemon

sudo systemctl daemon-reload
sudo systemctl restart docker

Build the image

Then you should run the build using buildtime-only proxy configuration:

docker build --build-arg http_proxy= --build-arg https_proxy= -t my_app .

TBC: is --build-args needed for yum update only ?

Run containers behind a proxy

Here the context is a bit different: we want a running container to access the web. Generraly speaking, it may not be the best idea in production environments, but it may still greatly help you to test or develop inside container.

Quick and dirty: rely on another container to provide the proxy

The simplest way is to use an already existing container, made specifically to provide transparent cntlm proxy service to others through Docker -link capability. It allows your application to address the proxy by name.

You should rather build this container from source (rather than blindly downloading it) as you will entrust it sufficiently with your logins and passwords.

Several cntml proxies are available, I choose to use jaschac/cntlm.

Download / build image with:

docker pull jaschac/cntlm

Start jashac/cntlm container:

docker run --name cntlm -e CNTLM_USERNAME=your_username -e CNTLM_DOMAIN=your_domain -e CNTLM_PROXY_URL=your_parent_ proxy -e CNTLM_PROXY_PORT=your_parent_proxy_port -e CNTLM_PASSNTLMv2=yourhash -d jaschac/cntlm

Then start your applciation container with:

docker run --link cntlm:cntlm -it my_app /bin/bash

Note the –link option that allow your application to resolve the cntlm host destite in another container.

Optional: set the proxy env in the dockerfile:

ENV http_proxy http://cntlm:3128
ENV https_proxy https://cntlm:3128

Make your container aware of the external proxy

Use the same address (corresponding to Windows through Virtual box) to let your container access the Windows cntlm proxy at runtime.

TBD: remains to be tested

ENV http_proxy
ENV https_proxy

List Sharepoint documents through REST API and python

Albert uses Sharepoint 2013 to store several GB of documents.

Albert needs to be able to list and possibly extract the documents in a comuter readable format, like ls would do on Unix. Of Course, he is a bit in a rush and has nothing but a corporate laptop without much privileges to do the job….

To make things simpler, although the Sharepoint site is hosted by his company, he has only a standard user web access and no specific provilege on the server or a powershell environment that would allow to interrogate it.

What’s next ?

Using Python, we can quite simply rely on Sharepoint REST API to perform basic queries.


Use winpyton

A portable Pyhton

Installing Python 3 and needed libraries may be tricky in a corporate environment, in particular when the web is accessed through a NTLM proxy that also rewrites SSL certificates.

I ended up installing Winpython (portable environment that bundles a recent PIP version).

using pip to access behind a proxy

By default something like pip --proxy=http://user:pass@proxyAddress:proxyPort
should do the trick.
I rely on a local CNTML proxy to authenticate my requests to the corporate proxy, as this avoid having to manage the account/password  in the commands
pip --proxy=http://localhost:3128 install my_special_package

However in my case the proxy rewrites SSL certificates and sign them with a corporate cert. I need to tell pip to ignore certificate validation.

C:\WinPython-64bit-\scripts>pip --proxy=http://localhost:3128 --trusted-host install my_special_package

Ideally we should be able to tell pip to trust the corporate certifcate (did not work in my case though, possibly due to a problem of cascading certs.):

pip --cert /etc/ssl/certs/FOO_Root_CA.pem install my_special_package

Installing dependencies

We will also need to authicate through NTLM to access the Sharepoint server(basic auth as shown in most online sample does not work here, we get error 401).

pip --proxy=http://localhost:3128 --trusted-host install requests
# requests_ntlm package to authenticate http requests
pip --proxy=http://localhost:3128 --trusted-host install requests_ntlm
# sharepoint lib... that did not work though
pip --proxy=http://localhost:3128 --trusted-host install sharepoint

quick notes – improvements

I should rather use python-sharepoint library

Python-sharepoint library is expected abstract the REST API but I did not manage to use it, possibly due to a problem with NTLM opener.

See []

Use CAML to filter queries

REST API can use CAML to reduce and optimize queries. However, it will requiere that REST queries are send through POST (instead of GET) which may conplexify the code…. but definitly somehing to explore.

CNTLM daemon and tmpfiles.d setup in CentOS7

The issue: CNTLM only works if started manually

Daemon does not executes properly (but service start command returns no error).
[root@server ~]# service cntlmd start

However cntml works fine when started from terminal with same configuration.
[root@server ~]# cntlm -c /etc/cntlm.conf

To debug, the service logs are in /var/log/messages

A first attempt…

In my case, the user executing the service is not root but cntlm and it does not exists or cannot create the PID file.

  • open /etc/sysconfig/cntlmd, look for RUNAS=cntlm, and also the location of PID file.

  • create the cntml user and the PID directory with correct rights.

[root@server ~]# adduser cntlm
[root@server ~]# mkdir /var/run/cntlm
[root@server ~]# chown cntlm /var/run/cntlm/

Restart the service… and all is fine… until i restart the server. After reboot I notice that the freshly created PID directtory /var/run/cntlm has disappeared.

The reason is that /var/run is of type tmpfs and not persisted accross reboots !

A persistent solution

Enters tmpfiles.d…

We can use systemd-tmpfiles (manual) to automate the creation or cleaning of directories at boot time.

See  /usr/lib/tmpfiles.d/ for example of existing configs (and write to /etc/tmpfiles.d/* override them).

Create an config for cntlm:

[root@server ~]# gvim /etc/tmpfiles.d/cntlmd.conf
#Type Path Mode UID  GID  Age Argument
d    /var/run/cntlm   0755 cntlm cntlm - -

Test it manually before reboot.

systemd-tmpfiles --create /etc/tmpfiles.d/cntlmd.conf

Eclipse through Ntlm proxy using cntlm


Latest Eclipse version (LUNA, MARS) are not always able to access internet through an NTLM proxy.

This makes updating Eclipse or installing a new feature pretty impossible.

When the web proxy requires NTLM authentication, Eclipse fails to connect and returns a authentication
error message even with various configurations:
– using native proxy support fails
– using manual settings (and providing my Windows domain, username, password) fails.

Typical error:

Some sites could not be found.  See the error log for more detail.
HTTP Proxy Authentication Required:<a href=""></a>
Proxy Authentication Required
HTTP Proxy Authentication Required:<a href=""></a>
Proxy Authentication Required
HTTP Proxy Authentication Required:<a href=""></a>
Proxy Authentication Required
HTTP Proxy Authentication Required:<a href=""></a>
Proxy Authentication Required

In preceding versions, I was able to make Eclipse work by using options in the ‘Eclipse.ini’ file but this do not work anymore.

Another workaround consist to replace the version of HTTPClient library of eclipse (either direcly by changing a jar or by installing – offline- a custom plugin that does it for us. I would not recommend this solution. It helps first later conflicts with updates or additional package.

Using CNTML as a local proxy

CNTML ([])is a small local proxy, that is able to authenticate you against the Enterprise NTLM proxy once for all and forward your requests without additional authentication.

It appears that Ecplise is ablte to traverse an NTLM proxy but not to authenticate against it.

I deploy CNTML on a local machine, provide it with my NTLM crendentials and the target enterprise proxy.
– CNTML is started and listen to localhost:3128
– Eclipse is configured to send traffic to localhost:3128
– CNTML authenticate against corporateProxy:3128
– CNTML forwards requests to corporateProxy:3128
– … Eclipse gets the response.

CNTML setup

Plenty of detailled examples through the web, see [] for windows.

A summary:

  • DL/Install CNTML
  • Update cntlm.ini (or /etc/cntml.conf)
      * Add target proxy + port
      * Restrict to localhost
      * update username, domain , do not provide clear password there (exept for test)

  • run cntlm -c cntlm.ini -I -M <a href=""></a> to be prompted for password

  • cntml return hashed password, store it to cntml.ini

sample CNTLM sartup bat

Use the following bat file if cannot setup a service.

set cntlmexe=C:\apps\cntlm-0.92.3\cntlm.exe
set cntlmconf=C:\apps\cntlm-0.92.3\cntlm.ini

REM ------------- start normally and verbose
%cntlmexe% -v -c %cntlmconf%

REM ------------- start with password prompt to produce a hash
REM %cntlmexe% -v -I -H -c %cntlmconf%

REM ------------- start with password prompt to test
REM %cntlmexe% -I -c %cntlmconf% -M<a href=""></a>

Configure Eclipse to use local proxy

Set up Eclipse to use localhost:3128 as a proxy.

OSX full HD crash and recovery

Quick notes on fixing my mac main HD.

Context / symptoms

  • 320GB OSX HD almost full (between 1 and 3GB free)
  • Random shut down of the host (kernel panic ?)

Startup shortcuts

  • Boot to single user mode (cmd + s on start)
  • Boot choice:  press ALT at startup for boot menu.

Tests done / unsucesfful

Attempt standard boot

 – display a progress bar (I suspect a fs check is done), then login screen is displayed but desktop never finishes to load.
 – OS hangs, cannot launch anything nor open any menu.
 – needs to shut down host by pressing power button several seconds.

Boot in single user mode

 – same symptoms (cmd +s on start)

Boot from os x install DVD

 – External Firewire enclosure. press ALT at startup for boot menu.
 – Boot external drive.
 – Run FS check through disk utility: FS corrupted. Attempted repair that failed.
 – I cannot mount the HD anymore.

Fixed through Disk Warrior

 – Make a USB bootable key from DiskWarrior DVD
 – Startup this image
 – Check drive and make it reparired by DW -> Works !

Other untested things:

 – Boot from external drive and use cmd line to extract files to another drive.
 – Install new HD and restore from old backup

Other notes

You should to try to rebuild the catalog file (B-tree) on the specified file system (which is HFS+) by specifying -r option for fsck, for example:

$ fsck.hfsplus -fryd /dev/sdd2

This option currently will only work if there is enough contiguous space on the specified file system for a new catalog file and if there is no damage to the leaf nodes in the existing catalog file (in other words, fsck is able to traverse each of the nodes in the requested btree successfully).

Of course, do the backup (whole image disk dump) before performing any disk operations, if you don’t want to risk of corrupting any data further more.

See more by running man fsck.hfsplus.

If this won’t help, try using some other tools to repair your disk, e.g.:

It took me a while, but here’s how the problem was solved:

  1. I connected an external Fireware hard drive, and used it to install OS X.
  2. I bough Disk Warrior and ran it on my Internal Harddrive. I let it rebuild the directory, and I’m back in business!
