Just wrapped up HackNet (Medium difficulty, Hack The Box) — what a ride!
Started with deep web enumeration and uncovered a template injection vulnerability in how dynamic content gets rendered. Crafted a payload, injected it into a user-controlled field, triggered the vulnerable path through a specific page interaction, and extracted sensitive account details that handed me valid SSH credentials as a low-priv user. From there, grabbing the user flag was a clean win.
For privilege escalation, enumeration from the foothold revealed a misconfigured, world-writable file-based cache backend in the Django app. Knowing the framework’s caching behavior and a known deserialization weakness, I built a malicious payload, poisoned the cache location, and triggered RCE as the web user. Further digging exposed encrypted database backups secured by public-key crypto; I obtained the key, cracked its passphrase, decrypted the dumps, and recovered a high-priv credential that let me escalate to root and snag the root flag.
