PHP websites are more vulnerable to attacks from even minor flaws due to evolving hacking tactics. To protect your PHP tech stack from future attacks, you must guarantee absolute security.
Threat
Attackers input malicious SQL queries into user fields, risking unauthorized database access.
Fix
Use prepared statements and parameterized queries instead of manual SQL queries to automatically sanitize user input and prevent SQL injection.
Threat
To steal data or hijack sessions, attackers insert malicious scripts into websites
Fix
Escape and sanitize user input in HTML to prevent script execution. Implement Content Security Policy (CSP) headers to restrict loaded content.
Threat
Attackers manipulate users' logged-in sessions, leading to involuntary actions.
Fix
Implement anti-CSRF tokens in forms to validate requests. Generate unique tokens for each session and verify them during form submission.
Threat
Malicious file uploads can lead to server access, denial of service, and code execution.
Fix
Validate file types/extensions both client-side and server-side. Store files outside the site root directory with unique filenames to prevent overwriting and mitigate risks.
Threat
Risk of session issues like hijacking or unauthorized access.
Fix
Use PHP functions like session_start(), and session_regenerate_id(), and set proper timeouts, and unique filenames.
Threat
Risk of unauthorized access due to weak password storage.
Fix
Use strong encryption (e.g., bcrypt, Argon2), enforce password complexity, and implement account lockout.
Threat
Risk of attackers executing arbitrary code via unprotected user inputs like eval().
Fix
Avoid using eval() and similar functions. Implement input sanitization, validation, and filtering.
