File changed: src/com/ibm/security/appscan/altoromutual/util/ServletUtil.javaEnhanced security for account cookie The diff adds two lines of code to enhance the security of the account cookie. The first line ensures that the cookie is sent only over a secure protocol like HTTPS. The second line mitigates the risk of client-side script accessing the protected cookie by setting the HttpOnly flag to true.
File changed: src/com/ibm/security/appscan/altoromutual/servlet/AdminServlet.javaAdded security check for trusted source and restructured code for better readability The code diff introduces a security check to verify if the request is coming from a trusted source before processing it. This is done by calling the isRequestFromTrustedSource(request) method. The implementation details of this method are not provided in the diff. If the request is not from a trusted source, an error message is returned.
The diff also restructures the code to improve readability. The code for adding an account, adding a user, and changing a password is now nested within the else block of the trusted source check. This ensures that these operations are only performed if the request is from a trusted source.
The diff does not introduce any changes to the logic of adding an account, adding a user, or changing a password. It only changes the order of these operations and wraps them within the trusted source check.
File changed: src/com/ibm/security/appscan/altoromutual/servlet/LoginServlet.javaSet HttpOnly and Secure flags on accountCookie The code diff adds two lines of code that modify the properties of the 'accountCookie' object. The 'setHttpOnly' method is called with the argument 'true', which restricts the cookie from being accessed through client-side scripts, enhancing security against cross-site scripting (XSS) attacks. The 'setSecure' method is also called with the argument 'true', which ensures that the cookie is only sent over secure (HTTPS) connections, providing protection against potential man-in-the-middle attacks.
File changed: WebContent/swagger/lib/marked.jsAdded validation to prevent inefficient regular expressions The code diff adds a validation check to the regular expression creation process. If the regular expression is inefficient (susceptible to catastrophic backtracking), an error is thrown. This is done by trying to create a new RegExp object with the provided regex string. If this fails, an error is thrown with a message indicating that the regular expression is inefficient. If the creation of the RegExp object is successful, the function proceeds as before.
File changed: src/com/ibm/security/appscan/altoromutual/util/DBUtil.javaRefactor SQL query to use PreparedStatement for security enhancement The code diff modifies the method of inserting data into the database. Instead of using a Statement object to execute the SQL query, it now uses a PreparedStatement. This change is made to prevent SQL injection attacks, as the PreparedStatement ensures that all input is properly escaped. The SQL query is now parameterized, with placeholders (?) used for the values to be inserted. These values are then set using the setString method of the PreparedStatement object.Refactoring SQL statement to use PreparedStatement The diff replaces a Statement object with a PreparedStatement object in order to execute an SQL update command. This change is made to prevent SQL injection attacks. The SQL command is now parameterized, with the password and username being set as parameters in the PreparedStatement.Refactor SQL statement to use PreparedStatement The diff replaces a Statement object with a PreparedStatement object for executing an SQL INSERT command. The change is made to prevent SQL injection attacks by using parameterized queries. The parameters for the SQL command are set using the setString method of the PreparedStatement object.Refactor addSpecialUser method to use PreparedStatement The diff modifies the addSpecialUser method. The original code used a Statement object to execute a SQL query, which is vulnerable to SQL injection attacks. The new code replaces the Statement with a PreparedStatement, which uses placeholders (?) for the values to be inserted into the database. This change helps to prevent SQL injection attacks by automatically escaping the input values. The SQL query string is also modified to use these placeholders. The executeUpdate method is used instead of the execute method to run the SQL query.Refactor SQL statement to use PreparedStatement The diff replaces a Statement object with a PreparedStatement object in order to execute an SQL INSERT command. The change is made to prevent SQL injection attacks by using parameterized queries. The username and account type are now set as parameters in the PreparedStatement, rather than being concatenated directly into the SQL string.Refactor SQL query to use PreparedStatement for security enhancement The diff changes the way the SQL query is executed in the getAccount method. Instead of using a Statement object, which is vulnerable to SQL injection, a PreparedStatement is used. This not only makes the code more secure, but also more efficient. The account number is now set as a parameter in the PreparedStatement, which prevents SQL injection attacks. The rest of the code remains the same, it fetches the account details and returns the first account if any are found, otherwise it returns null.Refactor getTransactions method to use PreparedStatement and improve SQL injection security The diff modifies the getTransactions method to use a PreparedStatement instead of a Statement for executing the SQL query. This change is made to prevent SQL injection attacks. The SQL query is also modified to use placeholders (?) for the account IDs and dates, which are set later using the setLong and setString methods of the PreparedStatement. The diff also adds a finally block to close the ResultSet, PreparedStatement, and Connection objects to free up database resources.Refactoring transferFunds method to use transactions and prepared statements The code diff modifies the transferFunds method to use transactions and prepared statements instead of simple statements. The changes include:
Starting a transaction block with connection.setAutoCommit(false).
Replacing the Statement object with a PreparedStatement object to execute SQL queries.
Removing some comments and adding new ones for better code readability.
Using the PreparedStatement's set methods to set parameters for the SQL queries instead of concatenating them into the query string.
Executing the SQL queries with the PreparedStatement's executeUpdate method.
Committing the transaction with connection.commit() at the end of the successful execution.
Rolling back the transaction with connection.rollback() in case of an exception.
Closing the PreparedStatement and Connection objects in a finally block to ensure resources are always released.
The SQL query that retrieves user information has been refactored to use a PreparedStatement instead of a Statement. This change is made to prevent SQL injection attacks, as the user input is now properly sanitized.
The username is now set as a parameter in the PreparedStatement, replacing the previous concatenation in the SQL query string.
The SQL query execution has been changed from using a Statement to a PreparedStatement. This change is made to prevent SQL injection attacks, as the PreparedStatement automatically escapes special characters.
The SQL query string is now parameterized, with placeholders (?) used for the user and password inputs. The actual values are set using the setString method of the PreparedStatement object.

The diff adds two lines of code to enhance the security of the account cookie. The first line ensures that the cookie is sent only over a secure protocol like HTTPS. The second line mitigates the risk of client-side script accessing the protected cookie by setting the HttpOnly flag to true.Security enhancement: Replaced Random with SecureRandom in makeRandomString method
The diff shows that the method makeRandomString() has been modified. The original method used the Random class to generate a random byte array, which was then converted to a string using the UTF-8 charset. The updated method replaces the Random class with the SecureRandom class, which provides a cryptographically strong random number generator. The rest of the method remains the same.Added security check for trusted source and restructured code for better readability

It only changes the order of these operations and wraps them within the trusted source check.
Security fix: Encode content for HTML to prevent Cross-Site Scripting (XSS) attacks
The change involves encoding the content for HTML before writing it to the response. This is done using the ESAPI encoder's encodeForHTML method. This change is intended to prevent potential Cross-Site Scripting (XSS) attacks by ensuring that any HTML content is properly encoded before being sent in the response.Added validation for surveyStep session attribute
The code diff adds a validation check for the 'step' parameter before setting it as a session attribute 'surveyStep'. If 'step' is null or contains characters other than alphanumeric, an IllegalArgumentException is thrown with the message "Invalid step parameter".Set HttpOnly and Secure flags on accountCookie
The code diff adds two lines of code that modify the properties of the 'accountCookie' object. The 'setHttpOnly' method is called with the argument 'true', which restricts the cookie from being accessed through client-side scripts, enhancing security against cross-site scripting (XSS) attacks.
