Web Application Vulnerabilities
Evidence
| URL | Evidence |
|---|---|
| http://mta-sts.mpca.at/ | Password input detected over insecure HTTP. Login form: ` |
Vulnerability description
We found that passwords are transmitted over a network without encryption. When users submit their passwords through an application or system, the lack of encryption means that the sensitive information is transmitted in plaintext, making it susceptible to interception and unauthorized access.
Risk description
The risk is that malicious actors could employ various techniques, such as packet sniffing or man-in-the-middle attacks, to capture plaintext passwords. Once intercepted, the attacker gains unauthorized access to user accounts, potentially leading to identity theft, unauthorized data access, or other malicious activities. The risk remains unchanged even if the password's form submission triggers a redirect response to an HTTPS page.
Recommendation
We recommend you to reconfigure the web server so it uses HTTPS - which encrypts the communication between the web browser and the server. This way, the attacker will not be able to obtain the clear-text passwords, even though he manages to intercept the network communication.

| http://mta-sts.mpca.at/ | http://mta-sts.mpca.at/ | Communication is made over unsecure, unencrypted HTTP. |
Vulnerability description
We noticed that the communication between the web browser and the server is done using the HTTP protocol, which transmits data unencrypted over the network.
Risk description
The risk is that an attacker who manages to intercept the communication at the network level can read and modify the data transmitted (including passwords, secret tokens, credit card information and other sensitive data).
Recommendation
We recommend you to reconfigure the web server to use HTTPS - which encrypts the communication between the web browser and the server.

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 |
|---|---|
| http://mta-sts.mpca.at/ | Response headers include the HTTP Content-Security-Policy security header with the following security issues: |
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.

| OWASP Top 10 - 2021 |
Evidence
| URL | Evidence |
|---|---|
| http://mta-sts.mpca.at/ | 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`.

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 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.

| http://mta-sts.mpca.at/ |
|
Vulnerability description
We have discovered that the target application presents a login interface that could be a potential target for attacks. While login interfaces are standard for user authentication, they can become vulnerabilities if not properly secured.
Risk description
The risk is that an attacker could use this interface to mount brute force attacks against known passwords and usernames combinations leaked throughout the web.
Recommendation
Ensure each interface is not bypassable using common knowledge of the application or leaked credentials using occasional password audits.
Infrastructure Vulnerabilities

Vulnerability description
We found that the Post Office Protocol (POP3) service is publicly accessible and doesn’t include STARTTLS capability. Email clients use the Post Office Protocol (POP) to download emails for user accounts. Some POP servers are initially set up to operate over an unsecured protocol. When email clients download email content through this plaintext protocol, it can pose a substantial risk to the organization's network, especially depending on which user account is set to receive the emails.
Risk description
Exposing this service online can enable attackers to conduct man-in-the-middle attacks, thereby gaining access to sensitive user credentials and the contents of emails. Given that POP3 operates via a plaintext protocol, the entirety of the data exchanged between the client and server is left unencrypted. This critical information could then be leveraged in further attacks on the organization's network.
Recommendation
We recommend turning off POP3 access over the Internet and instead using a Virtual Private Network (VPN) that mandates two-factor authentication (2FA). If the POP3 service is essential for business purposes, we recommend limiting access only from designated IP addresses using a firewall. Furthermore, activating STARTTLS capability (switching the connection to a secure communication) or utilizing Secure POP3 (POP3S) is recommended, as this protocol employs encryption.

|---|---|---|---|
| mta-sts.mpca.at | A | IPv4 address | 81.223.133.233 |
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.
