 The provided output reveals a common vulnerability in Windows services known as an unquoted service path. When the service executable path is not enclosed in quotes and contains spaces, Windows may incorrectly interpret the spaces, potentially leading to the execution of unintended programs.

 Details:

Command Explanation: The command vmic service get name, pathname, displayname, startmode | findstr /i auto | findstr /i /v "C:\\Windows\\" | findstr /i /v "" filters services that are set to start automatically and are not located in the Windows directory.

Output Interpretation: The output shows a service with a path C:\Program Files\A Subfolder\B Subfolder\SomeExecutable.exe which is not quoted. If a malicious user places an executable in C:\Program.exe, C:\Program Files\A.exe, or similar, it might get executed instead.

 References: Common Windows privilege escalation vulnerabilities include unquoted service paths. This vulnerability is well-documented in security resources and penetration testing guides.

The payload used by the penetration tester is a type of blind SQL injection attack that delays the response of the database by 15 seconds if the condition is true. This can be used to extract information from the database by asking a series of true or false questions. To prevent this type of attack, the best practice is to use parameterized queries, which separate the user input from the SQL statement and prevent the injection of malicious code. Encrypting passwords, encoding output, and sanitizing HTML are also good security measures, but they do not directly address the SQL injection vulnerability. References:

Time-Based Blind SQL Injection Attacks, Introduction and Microsoft SQL Server sections

A directory traversal attack, also known as a path traversal attack, is a method used to exploit insufficient security validation or sanitization of user-supplied input file names. The goal of this attack is to access directories and files that are stored outside the web root folder. By manipulating variables that reference files with “../” sequences and its variations, attackers can access restricted directories and execute commands outside of the web server’s root directory.

In the context of an application that allows users to upload documents to a cloud-based file server, an attacker might exploit a directory traversal vulnerability to navigate to directories that contain sensitive documents. If the file upload functionality is not properly secured, an attacker could upload a file with a payload designed to perform directory traversal. This could allow access to confidential files that are otherwise protected by the application's access control mechanisms.

Practical example from HTB Writeups like Forge and Anubis which demonstrate similar enumeration techniques leading to sensitive file disclosures​​​​.

Requiring local network access for the default Admin User account is a targeted measure to prevent unauthorized access from unfamiliar IP addresses, particularly those originating from outside the organization's network. This approach ensures that only devices physically connected to or authenticated within the local network can attempt to use the Admin User account, significantly reducing the risk of external attacks. Increasing password complexity and restricting simultaneous log-ins are good practices but do not directly address the issue of access from unfamiliar IPs. System hardening is broader and not specifically focused on the Admin User account issue.
