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.
Classification
| CWE | CWE-200 |
| OWASP Top 10 - 2017 | |
| OWASP Top 10 - 2021 |
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
Vulnerabilities found for Powerdns Authoritative Server 4.9.14
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 File Transfer Protocol (FTP) service. PORT STATE SERVICE VERSION 21/tcp open ftp Pure-FTPd
Vulnerability description
We found that the File Transfer Protocol (FTP) service is publicly accessible. The FTP enables client systems to connect to upload and download files. Nonetheless, FTP lacks encryption for the data exchanged between the server and the client, leaving all transferred data exposed in plaintext.
Risk description
Exposing this service online can enable attackers to execute man-in-the-middle attacks, capturing sensitive user credentials and the contents of files because FTP operates without encryption. The entirety of the communication between the client and the server remains unsecured in plaintext. This acquired information could further facilitate additional attacks within the network.
Recommendation
We recommend turning off FTP access over the Internet and instead using a Virtual Private Network (VPN) that mandates two-factor authentication (2FA). If the FTP service is essential for business purposes, we recommend limiting access only from designated IP addresses using a firewall. Furthermore, utilizing SFTP (Secure File Transfer Protocol) is recommended as this protocol employs encryption to secure data transfers.
Evidence
We managed to detect a publicly accessible Post Office Protocol (POP3) service. Starting Nmap ( https://nmap.org ) at 2026-06-29 15:48 EEST Nmap scan report for www.fedx.trackdelivery.store (51.89.157.43) Host is up (0.0014s latency). rDNS record for 51.89.157.43: cyber-a4.geebyteserver.com
PORT STATE SERVICE VERSION 995/tcp open ssl/pop3s?
Service detection performed. Please report any incorrect results at https://nmap.org/submit/ . Nmap done: 1 IP address (1 host up) scanned in 17.48 seconds
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.

| www.fedx.trackdelivery.store | CNAME | Canonical name | fedx.trackdelivery.store |
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.
