Security Misconfiguration and Exposed Services
Identify default credentials, open admin panels, verbose errors, and how to secure configurations.
What is Security Misconfiguration?
Security misconfiguration is one of the most prevalent web vulnerabilities (OWASP Top 10 #5). It occurs when security settings are left at insecure defaults, incomplete, or improperly configured across any layer of the stack.
Default Credentials
Many devices and software ship with default credentials (admin/admin, admin/password). Attackers scan for these systematically. Always change default credentials immediately upon deployment. Tools like Shodan index devices with default logins exposed to the internet.
