Web Application Vulnerabilities

Vulnerability description
We found that a cookie has been set without the <code>Secure</code> flag, which means the browser will send it over an unencrypted channel (plain HTTP) if such a request is made. The root cause for this usually revolves around misconfigurations in the code or server settings.
Recommendation
Whenever a cookie contains sensitive information or is a session token, then it should always be passed using an encrypted channel. Ensure that the secure flag is set for cookies containing such sensitive information.

Vulnerability description
We found that a cookie has been set without the <code>HttpOnly</code> flag, which means it can be accessed by potentially malicious JavaScript code running inside the web page. The root cause for this usually revolves around misconfigurations in the code or server settings.
Recommendation
Ensure that the HttpOnly flag is set for all cookies.

| https://www.dropbox.com/scl/fi/0cr246lez650fo3oec2v0/Action-Required-Employee-Compensation-Review-Due-For-Approval-01-17-25.paper | Response headers include the HTTP Content-Security-Policy security header with the following security issues:`object-src: We recommend restricting object-src to 'none' only. 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'. report-uri: report-uri is deprecated in CSP3. Please use the report-to directive instead.` |
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.
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.
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
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.
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).

The server responded with a 405 status code and the header: `Allow: GET, HEAD, POST` Request / Response |
Vulnerability description
We have noticed that the webserver responded with an Allow HTTP header when an OPTIONS HTTP request was sent. This method responds to requests by providing information about the methods available for the target resource.
Recommendation
We recommend that you check for unused HTTP methods or even better, disable the OPTIONS method. This can be done using your webserver configuration.

Recommendation
We recommend reviewing all DNS records associated with the domain and identifying and removing unused or obsolete records.
Vulnerability description
OS detection couldn't determine the operating system.
Recommendation
Vulnerability checks are skipped for ports that redirect to another port. We recommend scanning the redirected port directly.
