Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Signal K Server allows attackers to pollute internal state via unvalidated input. π **Consequences**: This leads to **Account Takeover** and **Remote Code Execution (RCE)**. Critical integrity loss!
Q2Root Cause? (CWE/Flaw)
π‘οΈ **Root Cause**: **CWE-78** (OS Command Injection). The flaw lies in failing to validate user inputs before processing, allowing malicious commands to be injected into the server's internal state.
Q3Who is affected? (Versions/Components)
π¦ **Affected**: **Signal K Server** (Product: signalk-server). π **Version**: All versions **prior to 2.19.0**. If you are running v2.18.x or lower, you are vulnerable!
Q4What can hackers do? (Privileges/Data)
π **Attacker Capabilities**: With **CVSS 9.8 (Critical)**, attackers can achieve: π Full Account Control, π» Remote Code Execution, π Complete Data Compromise (Confidentiality/Integrity/Availability).
π **Public Exploit**: **No**. The `pocs` array is empty. No public Proof-of-Concept or wild exploitation code is currently available. However, the severity suggests it will be targeted soon.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for **Signal K Server** instances. Check the version number in the UI or API response. If version < **2.19.0**, you are at risk. Look for command injection patterns in input fields.
Q8Is it fixed officially? (Patch/Mitigation)
β **Fixed?**: **Yes**. The vendor released patch **v2.19.0**. π **Action**: Upgrade immediately to v2.19.0 or later. See [GitHub Release](https://github.com/SignalK/signalk-server/releases/tag/v2.19.0).
Q9What if no patch? (Workaround)
π **No Patch Workaround**: If you cannot upgrade: π« Restrict network access to the server (firewall rules). π Disable unnecessary input fields. ποΈ Monitor logs for unusual command execution patterns.β¦
π₯ **Urgency**: **CRITICAL**. CVSS 9.8 is near-maximum. π **Priority**: Patch **IMMEDIATELY**. Do not wait for an exploit. Update to v2.19.0 today to prevent RCE and account hijacking.
