Vulnerability Scan Result

Vulnerability description

We found that the target application sets cookies with a domain scope that is too broad. Specifically, cookies intended for use within a particular application are configured in such a way that they can be accessed by multiple subdomains of the same primary domain.

Risk description

The risk is that a cookie set for example.com may be sent along with the requests sent to dev.example.com, calendar.example.com, hostedsite.example.com. Potentially risky websites under your main domain may access those cookies and use the victim session from the main site.

Recommendation

The `Domain` attribute should be set to the origin host to limit the scope to that particular server. For example if the application resides on server app.mysite.com, then it should be set to `Domain=app.mysite.com`

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.

Risk description

The risk is that an attacker who injects malicious JavaScript code on the page (e.g. by using an XSS attack) can access the cookie and can send it to another site. In case of a session cookie, this could lead to session hijacking.

Recommendation

Ensure that the HttpOnly flag is set for all cookies.

Vulnerability description

We noticed that the target application's server responses lack the <code>Referrer-Policy</code> HTTP header, which controls how much referrer information the browser will send with each request originated from the current web application.

Risk description

The risk is that if a user visits a web page (e.g. "http://example.com/pricing/") and clicks on a link from that page going to e.g. "https://www.google.com", the browser will send to Google the full originating URL in the `Referer` header, assuming the Referrer-Policy header is not set. The originating URL could be considered sensitive information and it could be used for user tracking.

Recommendation

The Referrer-Policy header should be configured on the server side to avoid user tracking and inadvertent information leakage. The value `no-referrer` of this header instructs the browser to omit the Referer header entirely.

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.

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).

Vulnerability description

Website is accessible.

Vulnerability description

We found that the DMARC record for the domain is not configured with sp policy, meaning that no policy is enforced for subdomains. When a DMARC record does not include a subdomain policy (sp directive), subdomains are not explicitly covered by the main domain's DMARC policy. This means that emails sent from subdomains (e.g., sub.example.com) may not be subject to the same DMARC enforcement as the main domain (example.com). As a result, attackers could potentially spoof emails from subdomains without being blocked or flagged, even if the main domain has a strict DMARC policy.

Recommendation

To mitigate the risk, we recommend configuring the DMARC record with a subdomain policy by adding the sp=reject or sp=quarantine directive. This will extend DMARC enforcement to all subdomains, preventing spoofing attempts and maintaining consistent security across both the main domain and its subdomains.

Vulnerability description

We found that the DMARC record for the domain is not configured with ruf tag. A missing ruf (forensic reporting) tag in a DMARC record indicates that the domain owner has not enabled the collection of detailed failure reports. Forensic reports provide valuable insights into specific instances where emails fail DMARC authentication. Without the ruf tag, the domain administrator loses the ability to receive and analyze these reports, making it difficult to investigate individual email failures or identify targeted phishing or spoofing attacks that may be exploiting weaknesses in the email authentication setup.

Recommendation

We recommend configuring the ruf tag in the DMARC record. This tag specifies where forensic reports should be sent, providing the domain owner with detailed data on DMARC validation failures. Forensic reports allow administrators to analyze why certain emails failed authentication, making it easier to fine-tune DMARC policies or address potential vulnerabilities. Ensure that the ruf email address belongs to a secure and trusted location capable of handling sensitive email data.

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.

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.
