The _list_file_get function in lib/Majordomo.pm in Majordomo 2 20110203 and earlier allows remote attackers to conduct directory traversal attacks and read arbitrary files via a ./.../ sequence in the "extra" parameter to the help command, which causes the regular expression to produce .. (dot dot) sequences. NOTE: this vulnerability is due to an incomplete fix for CVE-2011-0049.

Root cause

A user-supplied file name is joined with the allowed directory, but the result is never checked to confirm it is still inside that directory.

Fixed

ts
const file = path.resolve(ROOT, req.query.name);if (!file.startsWith(ROOT + path.sep)) {  return res.sendStatus(400);}res.sendFile(file);
