CVSS 9.8 Β· Critical

Q1What is this vulnerability? (Essence + Consequences)

🚨 **Essence**: METIS DFS exposes an **unauthenticated web shell** at `/console`. <br>πŸ’₯ **Consequences**: Remote attackers can execute arbitrary OS commands with **daemon privileges**, leading to full system compromise.

Q2Root Cause? (CWE/Flaw)

πŸ›‘οΈ **CWE-306**: Missing Authentication for Critical Function. <br>πŸ” **Flaw**: The `/console` endpoint lacks access controls, allowing direct interaction without credentials.

Q3Who is affected? (Versions/Components)

πŸ“¦ **Product**: METIS DFS (Data Fusion Server). <br>🏒 **Vendor**: METIS Cyberspace Technology SA. <br>⚠️ **Affected**: Versions **2.1.234-r18 and earlier**.

Q4What can hackers do? (Privileges/Data)

πŸ‘‘ **Privileges**: Executes commands as **daemon** user. <br>πŸ“‚ **Data**: Full read/write access to system files, databases, and configuration. <br>🌐 **Impact**: Complete server takeover.

Q5Is exploitation threshold high? (Auth/Config)

πŸ”“ **Auth**: **None required**. <br>🌍 **Network**: Remote exploitation possible (AV:N). <br>🎯 **Complexity**: Low (AC:L). Extremely easy to trigger.

Q6Is there a public Exp? (PoC/Wild Exploitation)

πŸ“ **PoC**: No public PoC listed in data. <br>πŸ”₯ **Wild Exploit**: Likely high risk due to low complexity and lack of auth. Monitor vendor advisories.
