Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Mlflow < 2.3.1 has a **Relative Path Traversal** flaw. π **Consequences**: Attackers can access files/directories **outside** the web root folder.β¦
π‘οΈ **Root Cause**: **CWE-23** (Relative Path Traversal). π The application fails to properly sanitize user input, allowing directory traversal sequences to escape the intended web root directory.
Q3Who is affected? (Versions/Components)
π₯ **Affected**: **Mlflow** users running versions **prior to 2.3.1**. π¦ Component: `mlflow/mlflow`. β οΈ If you are on v2.3.1 or later, you are safe.
Q4What can hackers do? (Privileges/Data)
π΅οΈ **Hacker Actions**: Read arbitrary files from the server. π Access config files, logs, or code stored outside the web root. π No direct RCE mentioned, but **data leakage** is severe.
Q5Is exploitation threshold high? (Auth/Config)
π **Threshold**: Likely **Low-Medium**. π Since it involves the web interface, remote exploitation is possible if the Mlflow UI is exposed. π« No specific auth bypass mentioned, but standard web access is the vector.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π§ͺ **Exploit**: Yes, public PoC exists. π See Nuclei templates on GitHub. π Wild exploitation is feasible for anyone with web access to the vulnerable instance.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for Mlflow version. π οΈ Use Nuclei template: `CVE-2023-2356.yaml`. π Check if you can request paths like `../../etc/passwd` via the web interface.
Q8Is it fixed officially? (Patch/Mitigation)
β **Fixed**: Yes! Official patch released in **Mlflow 2.3.1**. π Commit `f73147496e05c09a8b83d95fb4f1bf86696c6342` addresses the issue. π₯ Upgrade immediately.
Q9What if no patch? (Workaround)
π§ **No Patch?**: Restrict network access to Mlflow UI. π« Block external traffic. π Implement WAF rules to block `../` sequences. π Isolate the service from sensitive data stores.
Q10Is it urgent? (Priority Suggestion)
π₯ **Urgency**: **High**. π Published: 2023-04-28. β‘ Public PoC exists. π Upgrade to v2.3.1+ ASAP to prevent data exfiltration. Don't wait!
