Web Application Vulnerabilities
Evidence
| URL | Response URL | Evidence |
|---|---|---|
| http://tr.serverclient.5-link.com/ | http://tr.serverclient.5-link.com/ | 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
| URL | Evidence |
|---|---|
| http://tr.serverclient.5-link.com/ | 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.

|---|---|
| http://tr.serverclient.5-link.com/ | 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.

Evidence
| URL | Evidence |
|---|---|
| http://tr.serverclient.5-link.com/ | 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`.

Evidence
Vulnerability description
Website is accessible.
Evidence
| URL | Method | Summary |
|---|---|---|
| http://tr.serverclient.5-link.com/ | OPTIONS | We did a HTTP OPTIONS request. The server responded with a 200 status code and the header: `Allow: OPTIONS, TRACE, GET, HEAD, POST` Request / Response |
Vulnerability description
We have noticed that the webserver responded with an Allow HTTP header when an OPTIONS HTTP request was sent. This method responds to requests by providing information about the methods available for the target resource.
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.
Classification
| CWE | CWE-16 |

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.
Infrastructure Vulnerabilities
Evidence
We managed to detect a publicly accessible Remote Desktop Protocol (RDP) service. PORT STATE SERVICE VERSION 3389/tcp open ms-wbt-server Microsoft Terminal Services
Vulnerability description
We found that the Remote Desktop Protocol (RDP) service is publicly accessible. Attackers often look for the Remote Desktop Protocol service due to its capability to provide remote access and control of a server, usually one that operates on the Microsoft Windows operating system.
Risk description
Exposing this service online can enable attackers to launch authentication attacks, like guessing login credentials, potentially gaining unauthorized access. Attackers might use publicly available employee information for brute-force attacks. Vulnerabilities, such as unpatched software or protocol flaws, could also be exploited. An example is CVE-2019-0708 (Bluekeep) vulnerability. Additionally, integration with Active Directory Domain Services could allow attackers to move laterally across the network, accessing more systems and sensitive data.
Recommendation
We recommend turning off Remote Desktop Protocol access over the Internet and instead using a Virtual Private Network (VPN) that mandates two-factor authentication (2FA). Avoid permitting direct user authentication to Active Directory over the Internet to prevent attackers from engaging in password guessing or causing the lockout of legitimate domain user accounts. If the Remote Desktop Protocol service is essential for business purposes, limiting access to designated IP addresses is recommended.

Vulnerability description
Vulnerabilities found for jQuery 2.1.1
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.
Evidence
We managed to detect a publicly accessible Windows Remote Management (WinRM) service. PORT STATE SERVICE VERSION 5985/tcp open http Microsoft HTTPAPI httpd 2.0
Vulnerability description
We found that the Windows Remote Management (WinRM) service is publicly accessible. Network administrators often use remote administration protocols to control devices like servers and other essential systems. However, allowing these services to be accessible from the Internet can increase security risks, creating potential opportunities for attacks on the organization. Also, it operates in cleartext, making all traffic communicated through this protocol vulnerable to interception in its unencrypted form.
Risk description
Exposing this service online can enable attackers to launch authentication attacks, like guessing login credentials, and potentially gaining unauthorized access. Also, any vulnerabilities in the WinRM service or the underlying Windows OS can be exploited by attackers to gain access or elevate privileges. Given the high privilege level of WinRM, exploiting such vulnerabilities can lead to full system compromise This could also lead to the exposure of sensitive data such as user credentials and other sensitive information depending on the device being managed remotely since it uses a cleartext transfer of data. If an attacker intercepts these credentials, they might gain unauthorized access to the device.
Recommendation
We recommend turning off WinRM access over the Internet and instead using a Virtual Private Network (VPN) that mandates two-factor authentication (2FA). If the WinRM service is essential for business purposes, we recommend limiting access only from designated IP addresses using a firewall. Furthermore, utilizing HTTPS with WinRM (port 5986) is recommended as this protocol employs encryption.
Evidence
We managed to detect a publicly accessible Remote Procedure Call (RPC) service. PORT STATE SERVICE VERSION 135/tcp open msrpc Microsoft Windows RPC
Vulnerability description
We found that the Windows Remote Procedure Call (RPC) service is publicly accessible. RPC is a protocol that one program can use to request a service from a program located on another computer in a network.
Risk description
Exposing this service online can enable attackers to launch attacks, including unauthorized access, remote code execution, information disclosure, denial of service (DoS), and potential lateral movement within the network.
Recommendation
We recommend turning off RPC access over the Internet and instead using a Virtual Private Network (VPN) that mandates two-factor authentication (2FA). If the RPC service is essential for business purposes, we recommend limiting access only from designated IP addresses using a firewall.
Evidence
We managed to detect that jQuery has reached the End-of-Life (EOL).
Version detected: 2.1.1 Latest version for the cycle: 2.2.4 This release cycle (2) doesn't have long-term-support (LTS). The cycle was released on 2013-04-18 and its latest release date was 2016-05-20.
Risk description
Using end-of-life (EOL) software poses significant security risks for organizations. EOL software no longer receives updates, including critical security patches. This creates a vulnerability landscape where known and potentially new security flaws remain unaddressed, making the software an attractive target for malicious actors. Attackers can exploit these vulnerabilities to gain unauthorized access, disrupt services, or steal sensitive data. Moreover, without updates, compatibility issues arise with newer technologies, leading to operational inefficiencies and increased potential for system failures. Additionally, regulatory and compliance risks accompany the use of EOL software. Many industries have strict data protection regulations that require up-to-date software to ensure the highest security standards. Non-compliance can result in hefty fines and legal consequences. Organizations also risk damaging their reputation if a breach occurs due to outdated software, eroding customer trust and potentially leading to a loss of business. Therefore, continuing to use EOL software undermines both security posture and business integrity, necessitating timely upgrades and proactive risk management strategies.
Recommendation
To mitigate the risks associated with end-of-life (EOL) software, it's crucial to take proactive steps. Start by identifying any EOL software currently in use within your organization. Once identified, prioritize upgrading or replacing these applications with supported versions that receive regular updates and security patches. This not only helps close security gaps but also ensures better compatibility with newer technologies, enhancing overall system efficiency and reliability.Additionally, develop a comprehensive software lifecycle management plan. This plan should include regular audits to identify upcoming EOL dates and a schedule for timely updates or replacements. Train your IT staff and users about the importance of keeping software up to date and the risks associated with using outdated versions. By maintaining a proactive approach to software management, you can significantly reduce security risks, ensure compliance with industry regulations, and protect your organization's reputation and customer trust.

|---|---|---|---|
| tr.serverclient.5-link.com | A | IPv4 address | 220.130.25.71 |
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.
