Open Web Application Security Project (OWASP) is a non-profit global community promoting application security across the Web. It is highly credible and as a result, many application developers consider it crucial for web application security guidance. Every developer needs to understand code security vulnerabilities to avoid the cost associated with security failures. Vulnerabilities are compiled j based on their prevalence, business impact, delectability, and ease of exploitability. These are owasp top 10 vulnerabilities include:
Table of Contents
. Injection
This happens when a query or command is used to insert untrusted data into the interpreter through SOQ, OS, NoSQL, or LDAP injection. Such hostile data injected through the vector may trick the interpreter to enable the application to do unintended commands or access data without proper authentication.
Remediation
Use a safe API to eliminate the interpreter
Separate commands from data to avoid vulnerability to attacks that replace data with unintended command
Have an intrusion detection system that identifies suspicious client-side behaviors. Implement a positive server-side validation.
Have parameterized queries
- Brocken authentication
This vulnerability poses an enormous threat to applications’ security and the resource it accesses. It can also compromise other users identity connected to the same network and intruders may compromise passwords, security keys, and session tokens
Remediation
Implementation of multi-factor-authentication
Always use strong passwords
Monitor with care failed login attempts
For users with admin privileges, avoid deploying with default credentials
Do not include session IDs in URLs
- Sensitive data exposure
Unencrypted data is the main target for damaging exploits such as credit card fraud, identity theft, and other related crimes
Remediation
Implement SSL for data in transit
For data at rest:
Avoid storing sensitive data that is of no use
All sensitive data that needs to be stored should be encrypted
Catching responses with sensitive data should be disabled
Using internal file shares, remote code execution, denial of service attacks, file URI handler and internal port scanning can all be used by the external entities to disclose internal files.
Broken Access controls
Attackers can use this to access databases, servers, and admin panels, modify other user’s data, etc.
. Security Misconfiguration
This is the most common vulnerability. Various misconfigurations that expose firms to cybersecurity include:
Accepting insecure default setting
Open cloud storage
Incomplete configurations
Verbose error messages that with sensitive information
Misconfigured HTTP
. Cross-site Scripting(XSS)
This is where an application includes untrusted data in a new web page without proper validation. As a result, client-side java scripts or HTML scripts use the web as an attack vector to attack the sessions, redirect the user to malicious sites or deface websites.
. Insecure deserialization
It can be used by hackers to conduct remote code execution and injection attacks. Hackers give themselves an admin role by deserializing an object and then serializing it again.
. Insufficient logging and monitoring
The duration between an attack and detection is relatively longer thereby giving hackers enough time to secure confidential information, interfere with servers, corrupt servers, and planting malicious codes.
Using components with known vulnerabilities
Open source components such as libraries and frameworks are incorporated into modern-day web applications and these serve as weak links that impact the security of the whole application.
