Security Vulnerabilities Guide

Understanding and fixing common web security vulnerabilities detected by VitaPulse

High

Weak TLS Protocol (TLS 1.0 / 1.1)

Your server supports outdated TLS versions (1.0 or 1.1) that have known cryptographic weaknesses.

Risk

TLS 1.0 and 1.1 are vulnerable to attacks like BEAST, POODLE, and CRIME. Attackers on the same network can exploit these weaknesses to decrypt traffic, steal session cookies, credentials, and personal data. Major browsers have deprecated these versions and may display security warnings to your users.

Solution

Disable TLS 1.0 and 1.1 on your server and enforce TLS 1.2 or 1.3. Update your server configuration (Apache, Nginx, IIS) to only accept modern protocols. Test with SSL Labs after changes.

Example

# Nginx
ssl_protocols TLSv1.2 TLSv1.3;
