Addressing Specific Vulnerability Types with AppScan SAST

AppScan SAST is a powerful tool for identifying and mitigating a wide range of security vulnerabilities in mobile applications. By statically analyzing your code, it can pinpoint potential weaknesses before they reach production, saving time and resources while significantly improving the security posture of your app. This section will delve into some common mobile app vulnerabilities and how AppScan SAST helps address them.

We’ll explore both vulnerable and secure coding examples, alongside practical remediation steps.

SQL Injection

SQL injection is a serious vulnerability where malicious SQL code is injected into an application’s input, allowing attackers to manipulate the database. AppScan SAST detects potential SQL injection flaws by analyzing how your application handles user-supplied data in database queries.

Vulnerable Code (Android, using raw query):String query = “SELECT

FROM users WHERE username = ‘” + username + “‘ AND password = ‘” + password + “‘”;

Secure Code (Android, using parameterized queries):String query = “SELECTFROM users WHERE username = ? AND password = ?”;SQLiteDatabase db = this.getWritableDatabase();Cursor cursor = db.rawQuery(query, new String[] username, password);

Remediation involves consistently using parameterized queries or prepared statements to prevent direct concatenation of user input into SQL queries. AppScan SAST will highlight lines of code vulnerable to SQL injection and suggest using parameterized queries as a solution.

Cross-Site Scripting (XSS)

Cross-site scripting (XSS) occurs when an attacker injects malicious scripts into a web application that are then executed by the user’s browser. In mobile apps, this can happen when user-supplied data is displayed without proper sanitization. AppScan SAST identifies potential XSS vulnerabilities by analyzing how your app handles user input displayed on the UI.

Vulnerable Code (Swift, displaying user input directly):let usernameLabel = UILabel()usernameLabel.text = userInput

Secure Code (Swift, escaping HTML entities):let usernameLabel = UILabel()usernameLabel.text = userInput.htmlEncoded

Remediation for XSS involves consistently encoding or escaping user-supplied data before displaying it. This prevents malicious scripts from being executed. AppScan SAST flags instances where data is displayed without proper encoding, advising the use of appropriate escaping mechanisms.

Insecure Data Storage, Secure your mobile applications with appscans sast capabilities

Storing sensitive data like passwords or API keys directly in the application’s code or without proper encryption is a major security risk. AppScan SAST analyzes your code to detect hardcoded sensitive information and insecure storage practices.

Vulnerable Code (Java, hardcoded API key):String apiKey = “your_secret_api_key”;

Secure Code (Java, retrieving API key from secure configuration):String apiKey = getString(R.string.api_key);

Remediation involves using secure configuration mechanisms (environment variables, secure keystores) to manage sensitive data and encrypting data at rest and in transit. AppScan SAST identifies hardcoded secrets and recommends using secure storage mechanisms and encryption techniques.

Insecure Network Communication

Mobile apps often communicate with backend servers. If this communication isn’t secured, data can be intercepted by attackers. AppScan SAST can detect the use of insecure protocols (like HTTP instead of HTTPS).

Vulnerable Code (Objective-C, using HTTP):NSURL

url = [NSURL URLWithString

@”http://example.com/api”];

Secure Code (Objective-C, using HTTPS):NSURL

url = [NSURL URLWithString

@”https://example.com/api”];

Remediation involves ensuring all network communication uses HTTPS to encrypt data in transit. AppScan SAST highlights any instances of insecure network communication, suggesting a migration to HTTPS.
