What is Web Application?
Web Application is an application software running on a web browser stored on a remote server. Unlike software programs, they don’t need to run locally on the device as they are provided to users with network connection.
What is Web Application security?
Web Application security, also known as Web AppSec, is concerned with security issues surrounding websites, web applications and services related to them.
Web Application Security Risks
Broken Access Control
Access control maintains policy by preventing users from acting beyond the scope of their specified permissions. Failures generally result in unauthorized information exposure, data modification or deletion, or executing a business function beyond the user’s capabilities. Some of the vulnerabilities may include bypassing access control checks by tampering with parameters in URL, privilege elevation, token or metadata tampering, and force browsing to privileged pages as user with low privilege access.
This security issue might arise as a result of the use of old or weak cryptographic algorithms, protocols, or hard-coded passwords into applications, or when re-issuing cryptographic keys, or when depreciated hashing algorithms such as SHA1 are used. These issues often lead to sensitive data exposure.
Injections flaws involve sending data to an interpreter via query or command. Injection vulnerability can be exploited when user-supplied input in not validated, filtered or sanitized by system. Request can contain dynamic queries without context-aware escaping that are send directly to the interpreter, or it can contain SQL, NoSQL, OS, LDAP, or other command to retrieve data and exploit the application.
This security vulnerability can emerge when the application lacks required hardening on any part of the application stack, or when unnecessary features such as services, privileges, or accounts are enabled. This problem can also occur if default credentials are enabled and used, or if security features are not correctly configured. Security Misconfiguration flaw can lead to account takeover or potential data exposure.
Identification and Authentication Failures
To protect against authentication-related attacks, it is critical to confirm the user’s identity, authenticate the user, and manage the session. Applications that fail to authenticate and identify user properly may allow attacker to perform credential stuffing, brute force attacks, or if default credentials are still in use, or exposes identifiers in the URL. This flaw can lead to session hijacking, account takeover and possible data exposure.
Security Logging and Monitoring Failures
When logs are not protected for integrity or are not properly integrated into SIEM systems or alerts have poor design. In other words, lack of proper logging, alerting and monitoring can allow attackers to stay under the radar when performing at attack.
Server-Side Request Forgery
Server-Side Request Forgery (SSRF) may occur when web application fetches a remote resource without validating the user-supplied URL. Attack can force the application to send request to an unexpected destination even when it is protected by access control list or firewall.
