Hello, my name is Steve.
In today's digital landscape, the hypertext transfer protocol Http stands as one of the most widely
used protocols.
Web servers have evolved from serving static pages to handling interactive web applications with user
interaction.
This technological progress has opened the door to a potential vulnerabilities, particularly through
the tainted user input that can manipulate application logic and lead to unintended malicious actions.
The ease of web application development using modern framework has further contributed to an increase
in vulnerability.
Vulnerable applications on Internet.
To address these concerns.
We The Nmap scripting engine NSC offers a growing collection of Http scripts, transforming Nmap into
an invaluable web scanner for penetration testers with Nmap.
Not only can vulnerabilities as misconfigurations be identified, but web applications can also be crawled
to discover intriguing information.
This section aims to teach you how to leverage Nmap for web server auditing, ranging from automating
configuration checks to exploiting vulnerable web applications.
Additionally, I will introduce some of the NSC scripts that I have developed over the years, which
I found useful during web penetration test conducting at web.
So let's explore the various sections and topics covered in this section here of our course.
So we will firstly list supported Http methods.
With practical side, we will enumerate all the Http methods supported by a web server and web servers
over various Http methods, some of which can pose security risks.
So it's essential for system administrators and penetration testers to quickly identify these methods
and test their accessibility.
So in maps, Http method script provides a convenient way to accomplish this task and we will also discover
interesting files and folders on a web server.
We will do practical examples such as we will use Nmap to identify intriguing files and directories
on web servers.
And the explanation of this topic is in Nmap.
Http enum script enables the discovery of potentially sensitive or hidden files and folders on web servers.
This information can be valuable for further analysis and vulnerability assessment.
We will also do brute forcing Http authentication.
We will perform brute force attacks on Http authentication mechanisms because Nmap http brute script
automates the process of attempting various username and passwords combinations to gain unauthorized
access to protected web servers.
So this topic highlights the significance of the strong authentication credentials.
We will brute force web applications.
We will practically do Nmap to launch brute force attacks against web applications.
So in web boot scripts extend its capabilities to target web applications login forms.
So by systematically attempting different credentials.
So this script helps identify weak authentication mechanisms and emphasizes the importance of implementing
robust password policies.
We will also detect web application firewalls.
Practically, we will do examples how to detect the presence of web application firewalls EFS using
maps.
So Nmap has a http F detect scripts which aids in identifying the existence of a VFS that so a w by
w a f, I mean the web application firewall fire firewall.
And that may have been be protecting web applications and we will understand the presence of such security
measures and which is they are crucial for further penetration testing and vulnerability assessment.
And we will do a lot of examples, which we will also do X and x.
We will detect x and X vulnerabilities by x east side here.
Um, we will do practical examples such as identifying potential cross-site tracing XD cross site tracing
vulnerabilities with nmap and nmap.
Nmap http trace script http trace script detects if the trace method is enabled on web servers, which
could lead to excessive vulnerabilities.
So this topic emphasizes the importance of disabling the trace method to mitigate potential security
risks.
And we will also detect a famous ICS vulnerabilities.
So we will practically identify cross-site scripting vulnerabilities using Nmap, cross-device, cross-site
scripting.
I mean the ICS vulnerabilities using Nmap and Nmap http http x ed scripts helps identify potential vulnerabilities
in web applications by injecting specific payloads and analyzing the responses.
So this topic here demonstrates the importance of input, validation and output encoding to prevent
excess attacks.
And we will find we will with Nmap.
We will also find the SQL injection vulnerabilities.
We will discover SQL injection vulnerabilities with Nmap, which is Nmap http SQL injection script assist
in identifying potential SQL injection vulnerabilities in web applications.
So this topic highlights the significance of proper input, sanitization and prepared statements to
prevent these types of attacks.
We will also find web applications with default credentials.
We will identify web applications that may be using default credentials, for example, admin.
For example, if you have a WordPress site and didn't assign specific password for it, the probable
password will be admin, admin or admin pass here like this.
So we will scan these websites and Nmap http default account script checks for the presence of web applications
with default usernames and passwords.
So this recipe underscores the importance of changing default credentials to enhance security on your
website or server, we will detect insecure cross domain policies, which is we will identify insecure
cross domain policies in web applications.
And the Nmap also has the Http cross.
Http cross domain cross domain XML script.
Uh, with this script it will helps us to detect insecure cross domain policies which can lead to cross-site
scripting and cross-site request forgery vulnerabilities.
This highlights the need for proper cross domain policy configuration.
And here we will also detect exposed source code control system.
So identifying exposed source code control systems on web server.
So Nmap also has a uh http svn enum script that scans web servers for export subversion SVN repositories
revealing potentially sensitive source code and configuration files.
This underlines the significance of securing version control systems.
We will also audit the strength of Ciphersuites in SSL servers.
And with practical examples, we will evaluate the strength of cipher suites used in SSL, TLS connections.
And maps SSL enum ciphers.
Enum Cipher script can assist in outputting SSL TLS servers by examining the supported cipher suites
and their strength.
This result emphasizes the importance of using secure cipher suites to protect sensitive data.
So this section in this lecture we rely on the http https spider NSA libraries which offer extensive
configuration options.
So you will also learn how to get information and advanced configuration options related to Http, http
pipelining and web crawling.
So by utilizing the powerful Http scripts, you can enhance your web server auditing capabilities,
discover vulnerabilities, and strengthen the security of your web applications.
Stay proactive in your security efforts, and leverage these tools effectively to bolster your defenses.
Remember, responsible and ethical use of web application scanning tools is essential to protect systems
and networks and always have the proper authorization before conducting any security assessments or
penetration testing.
