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Outdated or vulnerable software components include versions of server-side software that are no longer supported or have known, publicly disclosed vulnerabilities. Using outdated software significantly increases the attack surface of a system and may allow unauthorized access, data leaks, or service disruptions.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.

OWASP Top 10 - 2021

Evidence

URL	Evidence
https://www.zusidisplay.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`.

Classification

CWE	CWE-693
OWASP Top 10 - 2017
OWASP Top 10 - 2021

Evidence

URL	Evidence
https://www.zusidisplay.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.

Evidence

URL	Evidence
https://www.zusidisplay.de/	Response headers do not include the Referrer-Policy HTTP security header as well as the `<meta/>` tag with name 'referrer' is not present in the response.

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://www.zusidisplay.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.

OWASP Top 10 - 2017
OWASP Top 10 - 2021

Evidence

URL
Missing: https://www.zusidisplay.de/.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.

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

Vulnerabilities found for jQuery 3.4.1

Risk description

These vulnerabilities expose the affected applications to the risk of unauthorized access to confidential data and possibly to denial of service attacks. An attacker could search for an appropriate exploit (or create one) for any of these vulnerabilities and use it to attack the system. Notes: - The vulnerabilities are identified based on the server's version.; - Only the first 5 vulnerabilities with the highest risk are shown for each port.; 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

We recommend you to upgrade the affected software to the latest version in order to eliminate the risks imposed by these vulnerabilities.

www.zusidisplay.de	AAAA	IPv6 address	2a0a:4cc0:c0:3282::1

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.
