Hack The Box: Era Machine Walkthrough – Medium Difficulity

Compromising the Era HTB machine involved chaining multiple weaknesses across the web layer and system layer. Initial access was obtained through an IDOR flaw in a file-sharing platform, allowing unrestricted file retrieval by enumerating numeric IDs. Leaked backups exposed source code, plaintext credentials, and an SSH private key, enabling lateral movement as eric. Further analysis uncovered a root-executed integrity-check binary in a world-writable directory. By extracting its signature, injecting it into a backdoored replacement, and waiting for the cron job to trigger, privileged execution was achieved. A resulting callback delivered full root access and allowed retrieval of the final flag.

Environment HTB: Full User & Root Flag Capture Through Exploitation

Captured both the user and root flags on the Environment HTB machine! We exploited Laravel 11.30.0 (PHP 8.2.28) vulnerabilities, including argument injection (CVE-2024-52301) and UniSharp Laravel Filemanager code injection. By bypassing authentication with `–env=preprod` and leveraging the profile upload feature, we executed a PHP reverse shell and retrieved the user flag via `cat user.txt`. For root access, we decrypted `keyvault.gpg` from the `.gnupg` directory to obtain credentials and exploited sudo with preserved BASH\_ENV by crafting a script that spawned a privileged shell, ultimately gaining full control of the system.

Hack The Box: Eureka Machine Walkthrough – Hard Dificulty

I enumerated Spring Boot Actuator endpoints, including /actuator/heapdump, which revealed plaintext credentials for oscar190. SSH login as oscar190 was successful, though the home directory was empty. Analysis of application.properties exposed Eureka credentials (EurekaSrvr:0scarPWDisTheB3st), granting access to the Eureka dashboard. By registering a malicious microservice, I retrieved miranda.wise credentials and captured the user flag. For privilege escalation, I identified a vulnerable log_analyse.sh script, performed command injection, and created a SUID bash shell in /tmp/bash. Executing this shell provided root access, allowing retrieval of the root flag and full control of the machine.

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.

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: Underpass Machine Walkthrough – Easy Difficulty

Successfully completed the “Underpass” machine on Hack The Box! For the user flag, I enumerated SNMP to discover a Daloradius instance, logged in with default credentials, cracked an MD5-hashed password for the svcMosh account, and used SSH to access the user flag in its home directory. To capture the root flag, I escalated privileges by exploiting sudo permissions on mosh-server, obtaining a session key and port to establish a root session and retrieve the flag from /root/root.txt.

Chained exploitation through misconfigured web app and internal services. We started by exploiting a WordPress plugin vulnerability (CVE-2023-26326) to upload files, followed by a file read vulnerability (CVE-2024-2961) for remote code execution. From there, we cracked the database credentials, gained SSH access as the shawking user, and leveraged a vulnerable API endpoint to escalate to root. This highlights how overlooked configurations and service misconfigurations can lead to a full server compromise.
