What serious security threats are there that solely rely on the client JavaScript code that the browser allows? One risk are buggy implementations which can be used to crash the browser or execute code by using heap spraying attacks or similar. These can be kind of mitigated within modern browsers by using ASLR, DEP, sandboxes and similar ...

According toOWASP, cross-site scripting (XSS) is one of the most widespread security risks in web applications. It occurs when an attacker injects malicious code into the client-side of an application. This normally happens when an application accepts untrusted (or user-supplied) data on a web page without escaping or validating it properly. A succ...
SQL databases are vulnerable to injection attacks where query parameters are exploited to execute arbitrary instructions. Below is an express framework router that is vulnerable to an SQL injection attack: In the example above, the application gets user IDs from URLs and retrieves the corresponding email address by querying the database. Two...
The client-side script on every browser can access all the content returned by an application to the server. This includes cookies that often contain sensitive data such as session IDs. Exposing session identifiers, whether in URLs, error messages, or logs is a bad practice that opens up an application to security issues like cross-site request for...
There are tons of security risks associated with the use of vulnerable application components. For instance, vulnerabilities in some libraries or other elements such as browser plugin code are a security loophole in your applications. To ensure the components you’re using do not compromise your application’s security, always keep up with the curren...
Adopting good coding practices can secure applications against common JavaScript vulnerabilities on both the client-side and server-side. When using JavaScript, always follow the following key guidelines for enhanced security: 1. Never trust user input 2. Use proper encoding/escaping 3. Sanitize user input 4. Define a content security policy 5. Set...

Jun 23, 2022 · Flash malware can now interact with JavaScript to help conceal malicious activity, making it much harder to detect and analyze. In 2014, Cisco Security Research observed growth in the use of Flash malware that interacts with JavaScript. The exploit is shared between two different files—one Flash, one JavaScript.

- Use a JavaScript linter. The easiest and simplest way of avoiding JavaScript security issues is linting your code. Linters are static code analysis tools that check your code for programmatic and stylistic errors, code smells, and known security exploits.
- Audit dependencies using a package manager. To keep third-party JavaScript security vulnerabilities in check, you need to track all the packages you’re using on your website.
- Add Subresource Integrity (SRI) checking to external scripts. As third-party or external scripts can be easily manipulated, checking their integrity before fetching them from the external server is one of the most essential JavaScript security best practices.
- Avoid using inline JavaScript and establish a Content Security Policy. Using inline script tags makes your website or application more vulnerable to cross-site scripting (XSS) attacks.

May 10, 2024 · These attacks can be avoided by encrypting sensitive data at rest (where it is stored) and using proper encryption and security measures to access that information (SSL, TLS, etc.). 6. Broken Authentication. This allows attackers to gain unauthorized access to sensitive data or impersonate legitimate users.
