MEDIUM
The severity is rated as MEDIUM due to the manual effort required for vulnerability scanning. While the absence of automated dependency management increases risk, the actual exploitability remains moderate without specific CVEs identified. Patches would be necessary based on the findings from any scan.

The issue at hand involves the vulnerability scanning of third-party libraries within a custom LAMP stack web application. The application is built using a mix of PHP, JavaScript, and .NET technologies without the use of package managers for dependency management. This makes it challenging to conduct automated vulnerability scans as most tools require structured dependency files like package-lock.json or similar. However, since there is a list of exact versions in use, it is feasible to scan these libraries against known CVE listings manually or with the right tool that can handle such cases. The importance lies in identifying and mitigating potential security flaws before they can be exploited by malicious actors, thereby safeguarding the application's integrity and confidentiality.

Affected Systems
  • Custom PHP/JS/.NET framework
  • LAMP stack
Remediation
  • Identify and list all third-party libraries and their exact versions in use within the application.
  • Use a tool like OWASP Dependency-Check or Snyk, which can scan for vulnerabilities without requiring structured dependency files. For example, run `dependency-check.sh --scan /path/to/app` to generate a report of known CVEs affecting your libraries.
  • Review the generated reports and prioritize updates based on CVSS scores or severity levels. Upgrade affected libraries by manually replacing them with patched versions from their respective sources.
Stack Impact

The impact is significant for common homelab stacks running similar custom frameworks without package managers, as it highlights the need for manual dependency tracking and vulnerability scanning.
