&lt;p&gt;SmartHire is a medium-difficulty Linux machine from HackTheBox. It hosts an AI hiring platform built with Flask on nginx, using &lt;strong&gt;MLflow&lt;/strong&gt; for model management. Initial access is gained via &lt;strong&gt;CVE-2024-37054&lt;/strong&gt;, a pickle deserialization vulnerability in MLflow that allows remote code execution by overwriting a model artifact with a malicious payload. Privilege escalation exploits a writable plugin directory combined with a sudo rule — a crafted &lt;code&gt;.pth&lt;/code&gt; file executed by &lt;code&gt;site.addsitedir()&lt;/code&gt; runs as root.&lt;/p&gt;</description></item></channel></rss>
