🧠 Vulnerability Classification Logic

+

🔴 HIGH RISK vulnerabilities are those that meet all of the following criteria:

  • MITRE ATT&CK T1190 Classification: The vulnerability enables "Exploit Public-Facing Application" attacks, meaning it can be directly exploited over the internet without user interaction
  • Network Attack Vector: CVSS analysis confirms the vulnerability has a NETWORK attack vector (not LOCAL, ADJACENT, or PHYSICAL)
  • Internet-Facing Deployment Analysis: Claude AI assesses that the vulnerable software is commonly deployed as an internet-facing service with HIGH or VERY_HIGH likelihood
  • Added to CISA KEV quickly: The CVE was issued less than 30 days prior to it being added to the KEV list. Otherwise you would have already patched it, right?
  • Added to KEV recently: The CVE was added to the KEV list in the last 14 days. Because you've patched it by the time it has been in active exploitation for 30 days, haven't you?

Each vulnerability undergoes deployment pattern analysis where Claude AI evaluates the typical deployment scenarios, and internet-facing likelihood.
