The Hack The Box (HTB) Oracle TNS Footprinting module teaches you how to analyze and potentially exploit the Oracle Transparent Network Substrate (TNS), the Oracle server communication protocol that facilitates communication between Oracle databases and applications over networks. Here's how to derive the solution and capture the flag.

A newly discovered vulnerability in ServiceNow, dubbed "Count(er) Strike, allows low-privileged—and in some cases, unauthenticated—users to extract sensitive data from ServiceNow tables, even when they should have no access to that information. With thousands of organizations relying on ServiceNow for workflow automation and sensitive business processes, the potential impact is especially concerning.

Network File System (NFS), developed by Sun Microsystems, serves a similar purpose to SMB, enabling access to file systems over a network as if they were local. NFS is primarily used between Linux and Unix systems, preventing direct communication between NFS clients and SMB servers. While NFSv3, which has been widely adopted, authenticates client computers, NFSv4 introduces a change, similar to the Windows SMB protocol, requiring user authentication. A notable advantage of NFSv4 over its predecessors is its simplicity in utilizing only one UDP or TCP port (2049), which simplifies the protocol’s use across firewalls.
