CVE-2022-46178

MeterSphere is a one-stop open source continuous testing platform, covering test management, interface testing, UI testing and performance testing. Versions prior to 2.5.1 allow users to upload a file, but do not validate the file name, which may lead to upload file to any path. The vulnerability has been fixed in v2.5.1. There are no workarounds.

There are no workarounds.

Summary

MeterSphere allow users to upload file, but not check the file name, may lead to upload file to any path if the file name in upload request is falsified.

Details

Metersphere's FileUtils.java didn't check the filePath.

    public static void createFile(String filePath, byte[] fileBytes) {
        File file = new File(filePath);
        if (file.exists()) {
            file.delete();
        }
        try {
            File dir = file.getParentFile();
            if (!dir.exists()) {
                dir.mkdirs();
            }
            file.createNewFile();
        } catch (Exception e) {
            LogUtil.error(e);
        }

        try (InputStream in = new ByteArrayInputStream(fileBytes); OutputStream out = new FileOutputStream(file)) {
            final int MAX = 4096;
            byte[] buf = new byte[MAX];
            for (int bytesRead = in.read(buf, 0, MAX); bytesRead != -1; bytesRead = in.read(buf, 0, MAX)) {
                out.write(buf, 0, bytesRead);
            }
        } catch (IOException e) {
            LogUtil.error(e);
            MSException.throwException(Translator.get("upload_fail"));
        }
    }

Patches
