MassBleed – An Open Source SSL Vulnerability Scanner

by Unallocated Author

MassBleed is an open source tool used for scanning SSL vulnerabilities in web applications. The tool can scan Heartbleed, CCS, Poodle, Winshock, and DROWN attack vulnerabilities in target web applications.

MassBleed Installation

MassBleed requires the following scripts to perform its scan.

Heartbleed POC
OpenSSL CCS script
Winshock Script

Heartbleed, OpenSSL, and Winshock scripts are available in the source code for MassBleed. The source code can be cloned from Github using the following command.

git clone https://github.com/1N3/MassBleed

Once MassBleed source code is downloaded, navigate to the tool’s directory (MassBleed) to change the file permissions of the scripts as shown below.

chmod +x massbleed
chmod +x heartbleed.py
chmod +x openssl_ccs.pl
chmod +x winshock.sh

change file permission

How MassBleed Works

MassBleed can perform bulk scan of supported vulnerabilities by running the following command.

./ massbleed.sh [CIDR or IP here] [port] [port # here] [proxy]

MassBleed does not scan the domain names but requires IP addresses of the target web applications. We can define a single IP address as target or range of IPs through CIDR (Classless Inter Domain Routing). We can also define a specific port to scan the target web application using the [port] argument. The [proxy] argument requires the configuration of proxychains.conf file at /etc/proxychains.conf to work. The [port] and [proxy] are optional arguments. For instance, we can run the MassBleed scanner in the following format to test the target IP address ( without specifying any proxy or port options.


MassBleed scans the target web application for all the vulnerabilities, such as DROWN, Heartbleed, OpenSSL CCS, Poodle, and Winshock. The tool also checks the supported Ciphers and OS version of the target web application.

We can also run the individual scripts available in the tool’s directory to scan specific vulnerability. For example, we can run heartbleed.py script from the tool’s directory to scan the target web application for the HeartBleed vulnerabilities.

python heartbleed.py

What Bunny Rating Does it Get?

MassBleed is a quick way of finding the SSL vulnerabilities in the web applications. Since the tool accepts IP addresses as input, more work is required to scan websites protected by services like Cloudflare IPs, as a result we are giving it three out of five bunnies

The __cfduid cookie is used to identify individual clients behind a shared IP address and apply security settings on a per-client basis.

cookie_notice_accepted and gdpr[allowed_cookies] are used to identify the choices made from the user regarding cookie consent.

For example, if a visitor is in a coffee shop where there may be several infected machines, but the specific visitor's machine is trusted (for example, because they completed a challenge within your Challenge Passage period), the cookie allows Cloudflare to identify that client and not challenge them again.

The _ga is asssociated with Google Universal Analytics - which is a significant update to Google's more commonly used analytics service. This cookie is used to distinguish unique users by assigning a randomly generated number as a client identifier. It is included in each page request in a site and used to calculate visitor, session and campaign data for the sites analytics reports. By default it is set to expire after 2 years, although this is customisable by website owners.

The _gat global object is used to create and retrieve tracker objects, from which all other methods are invoked. Therefore the methods in this list should be run only off a tracker object created using the _gat global variable. All other methods should be called using the _gaq global object for asynchronous tracking.

_gid works as a user navigates between web pages, they can use the gtag.js tagging library to record information about the page the user has seen (for example, the page's URL) in Google Analytics. The gtag.js tagging library uses HTTP Cookies to "remember" the user's previous interactions with the web pages.
