Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: MCP Watch suffers from **OS Command Injection**. ๐ **Consequences**: Attackers can execute **arbitrary commands** on the host system, leading to total system compromise.
Q2Root Cause? (CWE/Flaw)
๐ก๏ธ **Root Cause**: **CWE-78** (Improper Neutralization of Special Elements used in an OS Command). The software fails to sanitize inputs before passing them to the OS.
Q3Who is affected? (Versions/Components)
๐ฅ **Affected**: **MCP Watch** by **kapilduraphe**. Specifically versions **0.1.2 and earlier**. ๐ฆ It is a security scanner for Model Context Protocol servers.
Q4What can hackers do? (Privileges/Data)
๐ **Attacker Capabilities**: With **CVSS 9.8 (Critical)**, hackers gain **High** Confidentiality, Integrity, and Availability impact. They can likely achieve **full system control** and data theft.
Q5Is exploitation threshold high? (Auth/Config)
โก **Exploitation**: **Low Threshold**. Vector: **AV:N** (Network), **AC:L** (Low Complexity), **PR:N** (No Privileges Required), **UI:N** (No User Interaction). Easy to exploit remotely.
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ **Public Exploit**: **No PoC** listed in the data. However, the vulnerability is confirmed via GitHub Advisory. Wild exploitation is possible due to low complexity.
Q7How to self-check? (Features/Scanning)
๐ **Self-Check**: Scan for **MCP Watch** instances. Check version numbers against **0.1.2**. Look for unsanitized command inputs in the source code if auditing manually.
Q8Is it fixed officially? (Patch/Mitigation)
โ **Fix Status**: **Yes, Fixed**. A commit **e7da78c** addresses the issue. Refer to GitHub Advisory **GHSA-27m7-ffhq-jqrm** for the official patch details.
Q9What if no patch? (Workaround)
๐ง **No Patch Workaround**: Isolate the service. **Restrict network access** to the scanner. Do not run with **high privileges**. Validate all inputs if modifying code.
Q10Is it urgent? (Priority Suggestion)
๐ฅ **Urgency**: **CRITICAL**. CVSS **9.8** + Remote + No Auth = Immediate action required. Update to the patched version ASAP to prevent remote code execution.
