🧠 CVE Mapping & Threat Analysis: Turning Vulnerabilities Into Actionable Intelligence By CyberDudeBivash — Cybersecurity Architect | CVE Hunter | Founder of CyberDudeBivash.com

 


🔎 What is CVE Mapping?

CVE stands for Common Vulnerabilities and Exposures, a standardized system that assigns identifiers to publicly known vulnerabilities.

CVE Mapping is the process of linking these identifiers to:

  • Affected software versions

  • Known exploits or malware families

  • MITRE ATT&CK TTPs (Tactics, Techniques & Procedures)

  • Patch status

  • Risk scores (CVSS)

  • Threat actor usage

It’s the bridge between raw vulnerability data and operational defense. Without mapping, CVEs are just numbers.

🎯 Why CVE Mapping Matters in Cyber Defense

✅ For Blue Teams:

  • Prioritize patching based on exploitability

  • Correlate logs with active CVEs

  • Detect TTPs used by APTs exploiting mapped CVEs

✅ For Red Teams:

  • Weaponize unpatched CVEs (e.g., EternalBlue for lateral movement)

  • Use CVE mappings to build payloads for custom exploits

✅ For Threat Hunters:

  • Enrich threat intel with CVE-MITRE context

  • Build detection rules from mapped behaviors

🧩 Components of a CVE Mapping Framework

🧪 CVE Mapping in Action: A Real-World Breakdown

🔥 Case Study: CVE-2023-23397

Microsoft Outlook Elevation via NTLM Leak

PropertyData
CVECVE-2023-23397
CVSS9.8 Critical
Exploit TypeNTLM Relay Attack via Calendar invites
TacticInitial Access
MITRE ATT&CKT1071 (Application Layer Protocol), T1557.001 (Adversary-in-the-Middle)
Used ByAPT28 (Fancy Bear)
PatchKB5002358

💡 CVE Mapping enables detection logic like:

yaml
rule:
  title: Suspicious Outlook Reminder with UNC Path
  condition: OutlookCalendarEvent contains '\\attacker.com\share'

📌 CVE → MITRE ATT&CK Mapping

Here’s how you go from CVE to defensive insights using MITRE ATT&CK:

CVE IDTechniqueMITRE Tactic
CVE-2021-40444T1203Initial Access
CVE-2017-0144T1210, T1021Lateral Movement
CVE-2022-30190 (Follina)T1059.001Execution
CVE-2023-36884T1566.001, T1203Phishing & Exploitation
CVE-2024-30992T1547.001Persistence

This empowers blue teams to map detected activities back to specific CVEs and accelerate containment.

⚔️ CVE Mapping in Offensive Security

Red Teams and adversaries use CVE Mapping to:

  • Automate exploit selection in attack frameworks

  • Tailor phishing with known software CVEs

  • Deliver payloads post-exploitation using mapped TTPs

Example:

  • CVE-2019-19781 in Citrix

    • Tactic: Initial Access

    • Weaponized in ransomware deployments

    • Mapped to T1190 (Exploit Public-Facing App)

🧠 Integrating CVE Mapping into Threat Analysis

Threat Analysis becomes sharper when enriched with CVE data:

  1. Collect Threat Feeds: OSINT, MISP, ThreatFox, etc.

  2. Normalize Indicators: IPs, hashes, domain names

  3. Enrich with CVE + ATT&CK + Sigma

  4. Visualize in Tools: MISP, Splunk, Sentinel, TheHive

🔍 Example Insight:

"This IcedID campaign delivered a macro-enabled doc exploiting CVE-2017-0199, leading to SYSTEM privilege via CVE-2020-1472 (Zerologon), mapped to T1059.001 & T1068."

🔮 The Future of CVE Mapping

With AI and LLMs, we are now:

  • Auto-mapping malware families to CVEs using NLP

  • Predicting CVE exploitability before weaponization

  • Generating YARA/Sigma rules from mapped CVE behavior

➡️ CVE Mapping is no longer a manual task — it's a cyber defense automation pipeline.

✅ Conclusion: From Numbers to Threat Intel

“CVE Mapping turns raw vulnerability data into a battle plan. It connects the dots between exploit, actor, and defense.” — CyberDudeBivash

If you're serious about cyber defense, CVE Mapping must be in your daily ops. It’s how SOCs, CTIs, and Red Teams move from awareness to action.
