Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Path Traversal in Node-RED-Dashboard. <br>π₯ **Consequences**: Attackers can read arbitrary files on the server via directory traversal (`../`).β¦
π‘οΈ **Root Cause**: Improper input validation in the `ui_base/js/` endpoint. <br>π **Flaw**: The application fails to sanitize `..%2f` sequences, allowing access to parent directories. (CWE not specified in data).
Q3Who is affected? (Versions/Components)
π¦ **Affected**: Node-RED-Dashboard. <br>π **Version**: **Before 2.26.2**. <br>β **Fixed**: Version 2.26.2 and later are safe.
Q4What can hackers do? (Privileges/Data)
π **Attacker Actions**: <br>1. Traverse file system paths. <br>2. Read sensitive local files (config, source code, credentials). <br>3. Potential for further exploitation via included files.
Q5Is exploitation threshold high? (Auth/Config)
β οΈ **Threshold**: **Low/Medium**. <br>π **Auth**: Data does not specify authentication requirements. <br>βοΈ **Config**: Exploitation likely requires network access to the dashboard interface.β¦
π **Public Exp**: **Yes**. <br>π **PoC**: Available via Nuclei templates (ProjectDiscovery). <br>π **Wild Exp**: Likely easy to automate given the simple path traversal nature.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: <br>1. Check installed Node-RED-Dashboard version. <br>2. Scan for `ui_base/js/..%2f` requests. <br>3. Use Nuclei template: `CVE-2021-3223.yaml`.
