Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Mlflow < 2.9.2 suffers from **Local File Inclusion (LFI)** via path traversal. π **Consequences**: Attackers can read sensitive server files, modify data, or execute unauthorized admin ops.β¦
π‘οΈ **Root Cause**: **CWE-29** (Path Traversal). The flaw lies in how Mlflow handles file paths, allowing attackers to traverse directories and access restricted resources outside the intended scope. π
Q3Who is affected? (Versions/Components)
π₯ **Affected**: **Mlflow** versions **before 2.9.2**. Specifically, the `mlflow/mlflow` product. If you are running an older version, you are in the danger zone. β οΈ
Q4What can hackers do? (Privileges/Data)
π **Attacker Capabilities**: π **Read** sensitive files on the server. π **Modify** data. π§ **Execute** unauthorized administrative operations. The scope is broad: from data theft to full system compromise.
Q5Is exploitation threshold high? (Auth/Config)
π **Exploitation Threshold**: **Low**. The vulnerability is due to path traversal logic.β¦
π **Public Exp?**: **Yes**. A PoC exists in the **Nuclei templates** (ProjectDiscovery). GitHub commits and Huntr reports confirm the exploitability. Wild exploitation is possible given the public template. π£
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for **Mlflow** instances running version **< 2.9.2**. Use tools like **Nuclei** with the specific CVE-2023-6977 template. Look for path traversal indicators in logs or API responses. π΅οΈββοΈ
Q8Is it fixed officially? (Patch/Mitigation)
β **Official Fix**: **Yes**. The vulnerability was fixed in **Mlflow 2.9.2**. The GitHub commit `4bd7f27` addresses the path traversal issue. Upgrade immediately to patch. π οΈ
Q9What if no patch? (Workaround)
π§ **No Patch Workaround**: If you cannot upgrade, **restrict network access** to the Mlflow UI/API. Implement **WAF rules** to block path traversal sequences (e.g., `../`).β¦
π₯ **Urgency**: **HIGH**. Since a public PoC exists and the impact includes data theft and admin control, patching is critical. Do not delay. Update to v2.9.2+ ASAP. πββοΈπ¨
