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.

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.

I successfully captured both user and root flags by exploiting a file upload vulnerability to gain a web shell, extracting database credentials from config.php, and cracking the user hash to reveal the password Jenni_Luvs_Magic23. Using these credentials, I accessed the web application, discovered an SSH migration hint, and leveraged a Kerberos ticket (f.frizzle.ccache) to gain SSH access and retrieve the user flag with type user.txt. For the root flag, I escalated privileges using M.SchoolBus and SharpGPOAbuse to manipulate SleepGPO, applied changes with gpupdate.exe /force, extracted credentials with secretdump, and used wmiexec to secure a root-level shell, ultimately reading the root flag with type root.txt.

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.

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.

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.

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 …

I conquered the “Scepter” machine on Hack The Box, a challenging Active Directory exploit! Initially, I cracked weak .pfx certificate passwords using pfx2john and rockyou.txt. After syncing time, I extracted D.BAKER’s NTLM hash via Certipy and used BloodHound to reveal A.CARTER’s password reset privileges, exploiting ESC9 to capture the user flag. Subsequently, H.BROWN’s access to P.ADAMS’s altSecurityIdentities enabled an ESC14 attack, forging a certificate for passwordless authentication. Consequently, P.ADAMS’s DCSync rights allowed domain hash extraction, securing the root flag via Evil-WinRM.
