Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: BentoML < 1.4.8 suffers from **Insecure Deserialization**. ๐ **Consequences**: Attackers can execute **Arbitrary Code** on the server. This breaks confidentiality, integrity, and availability completely.
Q2Root Cause? (CWE/Flaw)
๐ก๏ธ **Root Cause**: **CWE-502** (Deserialization of Untrusted Data). The flaw lies in how BentoML processes unverified input, allowing malicious payloads to trigger code execution during the deserialization process.
Q3Who is affected? (Versions/Components)
๐ฅ **Affected**: Users running **BentoML versions prior to 1.4.8**. Specifically, version **1.4.7** is confirmed vulnerable. ๐ฆ Product: BentoML (Python AI model serving library).
Q4What can hackers do? (Privileges/Data)
๐ **Attacker Capabilities**: Full **Remote Code Execution (RCE)**. Hackers can run OS commands (e.g., `id`), steal data, and take over the system. โ ๏ธ Impact: **High** (C:H, I:H, A:H).
Q5Is exploitation threshold high? (Auth/Config)
๐ **Exploitation Threshold**: **LOW**. CVSS Vector: `AV:N/AC:L/PR:N/UI:N`. No authentication (PR:N), no user interaction (UI:N), and low complexity (AC:L). It is easily exploitable remotely.
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ฃ **Public Exploit**: **YES**. A PoC is available on GitHub (theGEBIRGE/CVE-2025-32375). It uses Docker to spin up the vulnerable version and `exploit.py` to trigger RCE via `ncat` listener.โฆ
๐ **Self-Check**: 1. Check your BentoML version (`pip show bentoml`). 2. If version < 1.4.8, you are vulnerable. 3. Scan for untrusted deserialization inputs in your custom BentoML services.โฆ
๐ฉน **Official Fix**: **YES**. The vulnerability was reported via GitHub Security Advisory (GHSA-7v4r-c989-xh26). The fix is included in **BentoML 1.4.8** and later. Update immediately! ๐ Published: 2025-04-09.
Q9What if no patch? (Workaround)
๐ง **No Patch Workaround**: If you cannot update, **strictly validate and sanitize all inputs** before deserialization. Disable any features that allow untrusted YAML/JSON deserialization.โฆ
๐ฅ **Urgency**: **CRITICAL**. RCE with no auth required is a top-tier threat. ๐ **Priority**: Patch immediately. Update to BentoML >= 1.4.8. Monitor for active exploitation using the public PoC. Don't wait!
