Risk description

The risk is that if the target application is vulnerable to XSS, lack of this header makes it easily exploitable by attackers.

Recommendation

Configure the Content-Security-Header to be sent with each HTTP response in order to apply the specific policies needed by the application.

Vulnerability description

Risk description

The risk is that lack of this header permits an attacker to force a victim user to initiate a clear-text HTTP connection to the server, thus opening the possibility to eavesdrop on the network traffic and extract sensitive information (e.g. session cookies).

Recommendation

The Strict-Transport-Security HTTP header should be sent with each HTTPS response. The syntax is as follows: `Strict-Transport-Security: max-age=<seconds>[; includeSubDomains]` The parameter `max-age` gives the time frame for requirement of HTTPS in seconds and should be chosen quite high, e.g. several months. A value below 7776000 is considered as too low by this scanner check. The flag `includeSubDomains` defines that the policy applies also for sub domains of the sender of the response.

Vulnerability description

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

Risk description

The risk is that lack of this header could make possible attacks such as Cross-Site Scripting or phishing in Internet Explorer browsers.

Recommendation

We recommend setting the X-Content-Type-Options header such as `X-Content-Type-Options: nosniff`.

Vulnerability description

Risk description

The risk exists that attackers could utilize information revealed in Internal Server Error messages to mount more targeted and effective attacks. Detailed error messages could, for example, expose a path traversal weakness (CWE-22) or other exploitable system vulnerabilities.

Recommendation

Ensure that error messages only contain minimal details that are useful to the intended audience, and nobody else. The messages need to strike the balance between being too cryptic and not being cryptic enough. They should not necessarily reveal the methods that were used to determine the error. Such detailed information can be used to refine the original attack to increase the chances of success. If errors must be tracked in some detail, capture them in log messages - but consider what could occur if the log messages can be viewed by attackers. Avoid recording highly sensitive information such as passwords in any form. Avoid inconsistent messaging that might accidentally tip off an attacker about internal state, such as whether a username is valid or not.

Vulnerability description

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

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

Risk description

The only risk this might present nowadays is revealing debug HTTP methods that can be used on the server. This can present a danger if any of those methods can lead to sensitive information, like authentication information, secret keys.

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.

Vulnerability description

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

Risk description

Emails that fail DMARC checks are still delivered to recipients. This leaves the domain highly vulnerable to email spoofing and phishing attacks, as malicious actors can impersonate the domain without facing any consequences from DMARC enforcement.

Recommendation

We recommend changing the DMARC policy to p=quarantine or, ideally, p=reject to actively block or quarantine emails that fail DMARC validation. This will enhance the security of your domain against spoofing and phishing attacks by ensuring that only legitimate emails are delivered.

Vulnerability description

Risk description

The ~all directive in an SPF record allows unauthorized emails to pass through some email servers, even though they fail SPF verification. While such emails may be marked as suspicious or placed into a spam folder, not all mail servers handle soft fail conditions consistently. This creates a risk that malicious actors can spoof the domain to send phishing emails or other fraudulent communications, potentially causing damage to the organization's reputation and leading to successful social engineering attacks.

Recommendation

We recommend changing the SPF record's ~all (soft fail) directive to -all (hard fail). The -all setting tells recipient mail servers to reject emails from any IP addresses not listed in the SPF record, providing stronger protection against email spoofing. Ensure that all legitimate IP addresses and services that send emails on behalf of your domain are properly included in the SPF record before implementing this change.

Vulnerability description

Risk description

Without a DKIM record, recipients have no way of verifying the integrity or authenticity of emails sent from the domain. This increases the likelihood of phishing and spoofing attacks, where malicious actors impersonate the domain to send fraudulent emails. This can lead to significant security incidents, such as credential theft, financial fraud, or the distribution of malware. Additionally, many email providers use DKIM as part of their spam and reputation filters, meaning that emails from a domain without DKIM may be flagged as spam or rejected, impacting the deliverability and reputation of legitimate emails.

Recommendation

We recommend implementing DKIM for your domain to enhance email security and protect your brand from email-based attacks. Generate a DKIM key pair (public and private keys), publish the public key in the DNS under the appropriate selector, and configure your email servers to sign outgoing messages using the private key. Ensure that the DKIM key length is at least 1024 bits to prevent cryptographic attacks. Regularly monitor DKIM signatures to ensure the system is functioning correctly and update keys periodically to maintain security.

Vulnerability description

Risk description

Without a subdomain policy (sp directive) in the DMARC record, subdomains are not protected by the same DMARC enforcement as the main domain, leaving them vulnerable to spoofing attacks. This inconsistency can be exploited by attackers to send phishing emails from subdomains, undermining the organization’s overall email security.

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

Risk description

The risk exists because without DNS Cookies, the server is vulnerable to DNS spoofing and amplification attacks. Attackers can manipulate responses or use the server in distributed denial-of-service (DDoS) attacks, compromising network availability and security.

Recommendation

We recommend enabling DNS Cookies to prevent spoofed DNS responses. Ensure proper cookie validation is implemented to mitigate DNS amplification attacks. Regularly update DNS servers to support the latest DNS security features.

Vulnerability description

Risk description

Without forensic reports (ruf), domain owners have limited visibility into the specifics of failed DMARC validation. This means potential malicious activity, such as email spoofing or phishing attempts, might go unnoticed until they result in more significant security breaches or reputational damage. Forensic reports allow for quick response to email abuses by providing detailed information about the failure, including the header information of the emails involved. The absence of this data hampers an organization's ability to identify and mitigate threats targeting its domain, increasing the risk of ongoing spoofing and fraud.

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

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.
