Duplicate code

Duplicate code

Description

The application's source code has duplicate code, which may cause unexpected behaviors.

Impact

- Reduce the maintainability of the code.
- Facilitate the propagation of errors if the duplicate code contains any vulnerability.

Recommendation

Ensure that source code does not have classes, functions or repeated methods.

Threat

Authenticated attacker from the Internet.

Expected Remediation Time

⌚ 15 minutes.

Compliant code

There is no commented out code in the production environment

                app.post("/register", function (req, res) {
  var username = req.body.username
  var password = req.body.password
  User.register(new User({ username: username }),
      password, function (err, user) {
    if (err) {
      return res.render("register");
    }
  });
});

            

Non compliant code

There is duplicate code with the same functionality in a production stage

                app.post("/register", function (req, res) {
  var username = req.body.username
  var password = req.body.password
  User.register(new User({ username: username }),
      password, function (err, user) {
    if (err) {
      return res.render("register");
    }
  });
});
app.post("/register", function (req, res) {
  var username = req.body.username
  var password = req.body.password
  User.register(new User({ username: username }),
      password, function (err, user) {
    if (err) {
      return res.render("register");
    }
  });
});
