Web Application Vulnerabilities

Evidence

URL	Evidence
https://kruknight.gitbook.io/daemon-of-hacking/	Response headers include the HTTP Content-Security-Policy security header with the following security issues:script-src: 'self' can be problematic if you host JSONP, Angular or user uploaded files. frame-ancestors: This directive tells the browser whether you want to allow your site to be framed or not. By preventing a browser from framing your site you can defend against attacks like clickjacking. The recommended value is 'none' or 'self'. script-src: ''unsafe-inline'' allows the execution of unsafe in-page scripts and event handlers. script-src: script-src should not allow '*' as source. This may enable execution of malicious JavaScript. script-src: 'unsafe-eval' allows the execution of code injected into DOM APIs such as eval().

Response headers include the HTTP Content-Security-Policy security header with the following security issues:script-src: 'self' can be problematic if you host JSONP, Angular or user uploaded files. frame-ancestors: This directive tells the browser whether you want to allow your site to be framed or not.

This may enable execution of malicious JavaScript. script-src: 'unsafe-eval' allows the execution of code injected into DOM APIs such as eval().

Vulnerability description

We noticed that the Content-Security-Policy (CSP) header configured for the web application includes unsafe directives. The CSP header activates a protection mechanism implemented in web browsers which prevents exploitation of Cross-Site Scripting vulnerabilities (XSS) by restricting the sources from which content can be loaded or executed.

Risk description

For example, if the unsafe-inline directive is present in the CSP header, the execution of inline scripts and event handlers is allowed. This can be exploited by an attacker to execute arbitrary JavaScript code in the context of the vulnerable application.

Recommendation

Remove the unsafe values from the directives, adopt nonces or hashes for safer inclusion of inline scripts if they are needed, and explicitly define the sources from which scripts, styles, images or other resources can be loaded.

Vulnerability description

We noticed that server software and technology details are exposed, potentially aiding attackers in tailoring specific exploits against identified systems and versions.

Risk description

The risk is that an attacker could use this information to mount specific attacks against the identified software type and version.

Recommendation

We recommend you to eliminate the information which permits the identification of software platform, technology, server and operating system: HTTP server headers, HTML meta information, etc.

Evidence

URL
https://kruknight.gitbook.io/daemon-of-hacking/robots.txt

Vulnerability description

We found the robots.txt on the target server. This file instructs web crawlers what URLs and endpoints of the web application they can visit and crawl. Website administrators often misuse this file while attempting to hide some web pages from the users.

Risk description

There is no particular security risk in having a robots.txt file. However, it's important to note that adding endpoints in it should not be considered a security measure, as this file can be directly accessed and read by anyone.

Recommendation

We recommend you to manually review the entries from robots.txt and remove the ones which lead to sensitive locations in the website (ex. administration panels, configuration files, etc).

Evidence

URL
Missing: https://kruknight.gitbook.io/daemon-of-hacking/.well-known/security.txt

Vulnerability description

We have noticed that the server is missing the security.txt file, which is considered a good practice for web security. It provides a standardized way for security researchers and the public to report security vulnerabilities or concerns by outlining the preferred method of contact and reporting procedures.

Risk description

There is no particular risk in not having a security.txt file for your server. However, this file is important because it offers a designated channel for reporting vulnerabilities and security issues.

Recommendation

We recommend you to implement the security.txt file according to the standard, in order to allow researchers or users report any security issues they find, improving the defensive mechanisms of your server.

URL	Method	Parameters	Evidence
https://kruknight.gitbook.io/daemon-of-hacking/	GET	Headers: User-Agent=Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/108.0.0.0 Safari/537.36	Email Address: youssefmohamed.a04@gmail.com

Vulnerability description

We noticed that this web application exposes email addresses, which might be unintended. While not inherently a vulnerability, this information could be leveraged in social engineering or spam related activities.

Risk description

The risk is that exposed email addresses within the application could be accessed by unauthorized parties. This could lead to privacy violations, spam, phishing attacks, or other forms of misuse.

Recommendation

Compartmentalize the application to have 'safe' areas where trust boundaries can be unambiguously drawn. Do not allow email addresses to go outside of the trust boundary, and always be careful when interfacing with a compartment outside of the safe area.

Vulnerability description

We found operating system paths returned in a HTTP response.

Risk description

The risk is that path disclosure may help an attacker learn more about the remote server's file system, thus increasing the effectiveness and precision of any future attacks.

Recommendation

Configure the web server to avoid leaking path information by using generic error messages that do not reveal any internal file paths. Make sure no server file is referred with its absolute path in the website code.

Risk description

An initial step for an attacker aiming to learn about an organization involves conducting searches on its domain names to uncover DNS records associated with the organization. This strategy aims to amass comprehensive insights into the target domain, enabling the attacker to outline the organization's external digital landscape. This gathered intelligence may subsequently serve as a foundation for launching attacks, including those based on social engineering techniques. DNS records pointing to services or servers that are no longer in use can provide an attacker with an easy entry point into the network.

Recommendation

We recommend reviewing all DNS records associated with the domain and identifying and removing unused or obsolete records.
