Hack The Box: Nocturnal Machine Walkthrough – Easy Difficulty

Captured the user flag by exploiting a file upload feature, unpacking .odt files to reveal a hidden password with xmllint, and injecting a reverse shell via the backup feature to get a www-data shell. Retrieved hashes from the nocturnal_database, cracked Tobias’s password (slowmotionapocalypse), and obtained the user flag. For the root flag, enumerated open ports, found port 8080 running ISPConfig, accessed it with admin credentials, identified the version, executed a public exploit, and gained root shell to capture the root flag.

Hack The Box: University Machine Walkthrough – Insane Walkthrough

Compromised university.htb by exploiting ReportLab RCE (CVE-2023-33733) to gain initial access as wao. Forged a professor certificate to impersonate george, then uploaded a malicious lecture to compromise Martin.T.

Escalated privileges by exploiting a scheduled task with a malicious .url file, used LocalPotato (CVE-2023-21746) for elevation on WS-3, and abused SeBackupPrivilege to extract NTDS.dit, ultimately retrieving Domain Admin credentials.

🔍 A great hands-on challenge combining web exploitation, privilege escalation, and Active Directory abuse.

Hack The Box: Code Machine Walkthrough – Easy Difficulity

Successfully exploited a code execution vulnerability in a web application by bypassing keyword restrictions through Python class enumeration, leading to a reverse shell as the app-production user and retrieval of the user.txt flag. Leveraged access to a SQLite database to crack credentials for the martin user and escalate privileges. Identified a backup script running with root privileges, crafted a malicious JSON payload to include the root directory in backups, and ultimately obtained the root.txt flag.

This engagement highlights the importance of secure input validation, credential management, and careful privilege delegation in application security.

Hack The Box: Cypher Machine Walkthrough – Medium Difficultyy

Successfully exploited a vulnerable Neo4j database via Cypher injection to extract credentials, gain SSH access, and retrieve the user flag. Then leveraged a misconfigured `bbot` binary with sudo rights to set the SUID bit on `/bin/bash`, escalating privileges to root and capturing the root flag. #Cybersecurity #Neo4j #CypherInjection #PrivilegeEscalation #Pentesting #EthicalHacking #InfoSec

Hack The Box: Dog Machine Walkthrough (Easy Difficulty)

Exploited exposed credentials in a .git repository to access Backdrop CMS, then used a remote command execution vulnerability (EDB-ID: 52021) for a reverse shell. Escalated to root by leveraging a misconfigured bee binary with sudo privileges, capturing both user and root flags.

Hack The Box: Cat Machine Walkthrough – Medium Diffculity

Hack The Box Success: Cat Machine Write-Up Published!

I’ve just published my personal write-up for the Cat machine on Hack The Box. In this challenge, I gained the user flag by exploiting a Stored XSS vulnerability to capture the admin session cookie, followed by an SQL Injection to extract credentials and gain SSH access. For the root flag, I took advantage of a vulnerable image processing script owned by root, crafting a payload to gain a root shell and retrieve the flag. The full write-up dives into each step, the logic behind the attacks, and key takeaways.

Hack The Box: Titanic Machine Walkthrough – Easy Difficulty

Just wrapped up a detailed walkthrough of the Hack The Box Titanic machine — an easy-rated challenge packed with valuable learning opportunities!

The journey started with exploiting a directory traversal vulnerability to access sensitive Gitea configuration files and extract user credentials. From there, I gained SSH access as the developer user and retrieved the user flag.

Privilege escalation was achieved by exploiting a critical ImageMagick vulnerability (CVE-2024-41817) in a writable directory, allowing arbitrary code execution via a crafted shared library. I also discovered the developer user had unrestricted sudo privileges, providing a straightforward path to root.

Hack The Box: Inflitrator Machine Walkthrough – Insane Difficulity

Successfully completed a two-stage Active Directory exploitation scenario involving both user access and privilege escalation. The first stage focused on identifying accounts that did not require Kerberos pre-authentication (AS-REP Roasting), allowing extraction and cracking of a user password hash to gain remote access and retrieve the user flag. In the second stage, a misconfigured certificate template (ESC4 vulnerability) within Active Directory Certificate Services was exploited to request a certificate impersonating a privileged user. This enabled full administrative access and retrieval of the root flag.

Hack The Box: Checker Machine Walkthrough – Hard Difficulty

Successfully exploited CVE-2023-1545 in Teampass to extract user credentials and leveraged CVE-2023-6199 in BookStack to obtain an OTP, gaining user-level access on the Checker machine. Privilege escalation was achieved by exploiting a sudo script interacting with shared memory, setting the SUID bit on /bin/bash to capture the root flag. A great example of combining application vulnerabilities with creative privilege escalation techniques!

Hack The Box: Heal Machine Walkthrough – Medium Difficulty

Writeup Summary: Heal (Hack The Box)

This box involved thorough enumeration that uncovered multiple subdomains, including a Ruby on Rails API. Initial access was gained by chaining a Local File Inclusion vulnerability with password cracking and exploiting a LimeSurvey plugin upload vulnerability. Privilege escalation was achieved by identifying and exploiting an exposed Consul service accessible through SSH port forwarding.

This challenge showcased key red teaming skills: web application exploitation, misconfiguration abuse, credential harvesting, and lateral movement.
