Vulnerability description
Outdated or vulnerable software components include versions of server-side software that are no longer supported or have known, publicly disclosed vulnerabilities. Using outdated software significantly increases the attack surface of a system and may allow unauthorized access, data leaks, or service disruptions. Vulnerabilities in these components are often well-documented and actively exploited by attackers. Without security patches or vendor support, any weaknesses remain unmitigated, exposing the application to risks. In some cases, even after patching, the reported version may remain unchanged, requiring manual verification.
Risk description
The risk is that an attacker could search for an appropriate exploit (or create one himself) for any of these vulnerabilities and use it to attack the system. Since the vulnerabilities were discovered using only version-based testing, the risk level for this finding will not exceed 'high' severity. Critical risks will be assigned to vulnerabilities identified through accurate active testing methods.
Recommendation
In order to eliminate the risk of these vulnerabilities, we recommend you check the installed software version and upgrade to the latest version.

Evidence
| URL | Cookie Name | Evidence |
|---|---|---|
| https://digital-marketing-masterclass.de/ | cache-with-varnish | Set-Cookie: cache-with-varnish=true |
Vulnerability description
We found that a cookie has been set without the Secure 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.
Risk description
The risk exists that an attacker will intercept the clear-text communication between the browser and the server and he will steal the cookie of the user. If this is a session cookie, the attacker could gain unauthorized access to the victim's web session.
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.

|---|---|---|
| https://digital-marketing-masterclass.de/ | cache-with-varnish | The server responded with Set-Cookie header(s) that does not specify the HttpOnly flag: Set-Cookie: cache-with-varnish=true |
Vulnerability description
We found that a cookie has been set without the HttpOnly 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.

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.
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 | Evidence |
|---|---|
| https://digital-marketing-masterclass.de/ | Response does not include the HTTP Content-Security-Policy security header or meta tag |
Vulnerability description
We noticed that the target application lacks the Content-Security-Policy (CSP) header in its HTTP responses. The CSP header is a security measure that instructs web browsers to enforce specific security rules, effectively preventing the exploitation of Cross-Site Scripting (XSS) vulnerabilities.
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.

|---|---|
| https://digital-marketing-masterclass.de/ | Response headers do not include the X-Content-Type-Options HTTP security header |
Vulnerability description
We noticed that the target application's server responses lack the X-Content-Type-Options header. This header is particularly important for preventing Internet Explorer from reinterpreting the content of a web page (MIME-sniffing) and thus overriding the value of the Content-Type header.
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`.

| https://digital-marketing-masterclass.de/ | Response headers do not include the Referrer-Policy HTTP security header as well as the |
Vulnerability description
We noticed that the target application's server responses lack the Referrer-Policy 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 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 | Evidence |
|---|---|
| https://digital-marketing-masterclass.de/ | Response headers do not include the HTTP Strict-Transport-Security header |
Vulnerability description
We noticed that the target application lacks the HTTP Strict-Transport-Security header in its responses. This security header is crucial as it instructs browsers to only establish secure (HTTPS) connections with the web server and reject any HTTP connections.
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
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.

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.

Infrastructure Vulnerabilities
Evidence
We managed to detect a publicly accessible SSH service. Starting Nmap ( https://nmap.org ) at 2026-05-16 01:17 EEST Nmap scan report for digital-marketing-masterclass.de (79.133.210.186) Host is up (0.022s latency).

Service detection performed. Please report any incorrect results at https://nmap.org/submit/ . Nmap done: 1 IP address (1 host up) scanned in 0.92 seconds
Vulnerability description
We found that the SSH service with username/password authentication is publicly accessible. Network administrators often use remote administration protocols to control devices like switches, routers, and other essential systems. However, allowing these services to be accessible via the Internet can increase security risks, creating potential opportunities for attacks on the organization.
Risk description
Exposing this service online with username/password authentication can enable attackers to launch authentication attacks, like guessing login credentials, and potentially gaining unauthorized access. Vulnerabilities, such as unpatched software, protocol flaws, or backdoors could also be exploited. An example is the CVE-2024-3094 (XZ Utils Backdoor) vulnerability.
Recommendation
We recommend turning off SSH with username/password authentication access over the Internet and instead using a Virtual Private Network (VPN) that mandates two-factor authentication (2FA). If the SSH service is essential for business purposes, we recommend limiting access only from designated IP addresses using a firewall. Furthermore, it is advisable to utilize SSH Public Key Authentication since it employs a key pair to verify the identity of a user or process.
Evidence
| Domain Queried | DNS Record Type | Description | Value |
|---|---|---|---|
| _dmarc.digital-marketing-masterclass.de | TXT | Text record | "v=DMARC1; p=none; rua=mailto:cz@gutschein-kompass.com; ruf=mailto:cz@gutschein-kompass.com; sp=none; adkim=r; aspf=r; pct=100" |
Vulnerability description
We found that the DMARC record for the domain is configured with sp=none, meaning that no policy is enforced for subdomains. This allows subdomains to send emails without being subject to DMARC checks, making it easier for attackers to spoof emails from these subdomains. Subdomains are often overlooked in email security, and attackers can exploit this misconfiguration to launch phishing or spoofing attacks from seemingly legitimate subdomains of a protected domain.
Risk description
When the DMARC record is configured with sp=none, subdomains are not subject to DMARC enforcement, allowing attackers to spoof emails from subdomains without being blocked. This creates a significant risk of phishing and impersonation attacks, where malicious emails appear to originate from trusted subdomains. These spoofed emails can be used to deceive users or damage the organization's reputation, undermining the security benefits of DMARC for the primary domain.
Recommendation
To mitigate the risk, we recommend that the subdomain policy should be updated to sp=reject to ensure that any email failing DMARC checks from subdomains is automatically rejected. This will help prevent unauthorized emails from being sent from subdomains, reducing the risk of spoofing and phishing. Additionally, it's important to regularly monitor DMARC reports to track email activity from subdomains and adjust policies as needed to maintain consistent security across the entire domain.

Vulnerability description
We found that the DKIM record uses common selectors. The use of common DKIM selectors such as default, test, dkim, or mail may indicate a lack of proper customization or key management. Attackers often target domains using such selectors because they suggest that the domain is relying on default configurations, which could be less secure and easier to exploit. This can increase the risk of DKIM key exposure or misuse.
Risk description
Using a common DKIM selector makes it easier for attackers to predict and exploit email authentication weaknesses. Attackers may attempt to find corresponding DKIM keys or improperly managed records associated with common selectors. If a common selector is coupled with a weak key length or poor key management practices, it significantly increases the likelihood of email spoofing and phishing attacks.
Recommendation
We recommend using unique, customized selectors for each DKIM key to make it more difficult for attackers to predict and target the domain's DKIM records. Regularly rotate selectors and associated keys to further strengthen the security of your domain's email authentication infrastructure.

Vulnerability description
We found that the target uses p=none in the DMARC policy. The DMARC policy set to p=none means that the domain owner is not taking any action on emails that fail DMARC validation. This configuration effectively disables enforcement, allowing potentially spoofed or fraudulent emails to be delivered without any additional scrutiny.
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.
Evidence
We found insecure DNS cookie usage on the following nameservers: evangeline.ns.cloudflare.com, gannon.ns.cloudflare.com
Vulnerability description
We found that the server does not implement DNS Cookies or uses them insecurely. DNS Cookies help prevent DNS-based attacks, such as spoofing and amplification attacks.
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.
Evidence

Vulnerability description
We found that the Sender Policy Framework (SPF) record for the domain is configured with ~all (soft fail), which indicates that emails from unauthorized IP addresses are not explicitly denied. Instead, the recipient mail server is instructed to treat these messages with suspicion but may still accept them. This configuration may not provide enough protection against email spoofing and unauthorized email delivery, leaving the domain more vulnerable to impersonation attempts.
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.

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.
