Known CVE Vulnerabilities in Outdated Services

Critical Severity Technical Guide

Vulnerability Description

A Common Vulnerabilities and Exposures (CVE) check identifies known security flaws in the software stacks detected on your server (such as outdated web servers, CMS systems, databases, or libraries). Leaving known CVEs unpatched makes it trivial for automated scanners and attackers to compromise the system.

Remediation Guide

To resolve this vulnerability, follow these config changes or developer practices:

1. Check the specific CVE identifiers in your WebScanify report. 2. Keep your package manager and base OS updated (e.g. running apt-get update && apt-get upgrade). 3. Disable banner headers (like server tokens) to prevent attackers from easily fingerprinting outdated software versions.

Verify Your Fix

After applying the remediation, run an external attack-surface scan to verify that the vulnerability is no longer detected by WebScanify.
