Application security threats are security risks associated with software applications. The following are some of the most common application security threats:

1. SQL Injection: An attack where malicious code is inserted into a SQL query to gain unauthorized access to sensitive data stored in a database.
2. Cross-Site Scripting (XSS): An attack where malicious code is injected into a web page viewed by other users, allowing the attacker to steal sensitive information or execute unauthorized actions.
3. Cross-Site Request Forgery (CSRF): An attack where a malicious website tricks a user into executing an action on another website, such as transferring funds or changing their password.
4. Malicious File Execution: An attack where a malicious file is executed on a user’s device, leading to a security breach.
5. Buffer Overflow: An attack where a large amount of data is sent to an application, causing it to crash or execute unintended actions.
6. Insufficient Logging and Monitoring: A lack of logging and monitoring of application activity can make it difficult to detect and respond to security threats.
7. Insecure Direct Object References: An attack where a malicious user gains access to sensitive information by manipulating URLs or other references to direct objects in the application.
8. Broken Authentication and Session Management: An attack where a malicious user is able to gain unauthorized access to an application by exploiting weaknesses in authentication and session management.
9. Insecure Cryptographic Storage: An attack where sensitive information, such as passwords and credit card numbers, is stored in an insecure manner, making it vulnerable to theft.

By understanding these common application security threats, organizations can take steps to prevent and mitigate these risks, such as implementing security best practices, using secure coding techniques, and performing regular security testing.
