The Most Common Findings
Based on thousands of scans, here are the vulnerabilities we find most often:
1. Outdated SSL/TLS Problem: Servers using deprecated TLS versions (1.0, 1.1) or weak cipher suites. Fix: Disable TLS 1.0/1.1, enable TLS 1.2/1.3, configure strong ciphers.
2. Missing Security Headers Problem: Web servers missing headers like HSTS, X-Frame-Options, CSP. Fix: Configure web server or CDN to add security headers.
3. Exposed Admin Panels Problem: Admin interfaces accessible from the internet. Fix: Restrict access by IP, require VPN, or move to internal network.
4. Default Credentials Problem: Devices and applications using factory default passwords. Fix: Change all default credentials, implement password policy.
5. Unpatched Software Problem: Systems running software with known vulnerabilities. Fix: Implement patch management, prioritize by severity.
6. Open RDP/SSH Problem: Remote access protocols exposed to the internet. Fix: Use VPN or zero-trust access, never expose directly.
7. Missing Email Authentication Problem: SPF, DKIM, or DMARC not configured or misconfigured. Fix: Implement all three with DMARC enforcement.
8. Information Disclosure Problem: Error messages, version numbers, or internal info exposed. Fix: Configure proper error handling, remove version headers.
Prioritization
Not all vulnerabilities are equal. Prioritize based on: - Exploitability (is there a working exploit?) - Exposure (is it internet-facing?) - Impact (what's the potential damage?)
ThreatMate automatically prioritizes findings to help you focus on what matters.
