Vuln Research
Exploit research workflow — from software version to working exploit.
Triage Order
- Identify exact software + version
- Search NVD for CVEs
- Check CVSS score — prioritize Critical (9.0+) / High (7.0+)
- Find PoC / exploit
- Assess exploitability (auth required, network access, mitigations)
- Run exploit or look for Metasploit module
Step 1 — Identify Version
# On target — common version fingerprinting
uname -r # Kernel
lsb_release -a # Linux distro
apache2 -v / nginx -v # Web server
php --version # PHP
mysql --version # MySQL
python3 --version
dpkg -l | grep <package> # Debian package version
rpm -qa | grep <package> # RHEL/CentOS
Step 2 — CVE Lookup
NVD (authoritative)
https://nvd.nist.gov/vuln/search?query=<product>+<version>
CLI via nvdlib (Python)
pip install nvdlib
python3 -c "
import nvdlib
cves = nvdlib.searchCVE(keywordSearch='apache 2.4.49', limit=10)
for c in cves:
print(c.id, c.score, c.descriptions[0].value[:120])
"
Via curl (NVD API v2)
curl -s "https://services.nvd.nist.gov/rest/json/cves/2.0?keywordSearch=OpenSSH+8.2&resultsPerPage=5" \
| jq '.vulnerabilities[].cve | {id: .id, score: .metrics.cvssMetricV31[0].cvssData.baseScore, desc: .descriptions[0].value[:100]}'
Step 3 — CVSS Triage
| Score | Severity | Action | |-------|----------|--------| | 9.0–10.0 | Critical | Exploit immediately — likely weaponized | | 7.0–8.9 | High | Check for PoC; often exploitable | | 4.0–6.9 | Medium | Exploit if conditions met (auth, local) | | 0.1–3.9 | Low | Deprioritize |
Key CVSS vectors to check:
- AV:N (Network) — remotely exploitable; highest value
- PR:N (No Privileges Required) — unauthenticated
- UI:N (No User Interaction) — autonomous exploitation
- S:C (Scope Changed) — impact beyond vulnerable component
Step 4 — Find Public Exploit / PoC
Sploitus (aggregates ExploitDB + PacketStorm + GitHub PoCs)
https://sploitus.com/?query=<CVE-ID>
https://sploitus.com/?query=<product>+<version>
PoC-in-GitHub
# Search GitHub for PoCs
curl -s "https://poc-in-github.motikan2010.net/api/v1/?cve_id=CVE-2021-44228" | jq '.pocs[]'
https://github.com/search?q=CVE-2021-44228+PoC&type=repositories&sort=updated
SearchSploit (offline)
searchsploit <product> <version>
searchsploit --cve <CVE-ID>
Exploit-DB (online)
https://www.exploit-db.com/search?cve=<CVE-ID>
Packetstorm
https://packetstormsecurity.com/search/?q=<CVE-ID>
Vulhub (Docker PoC environments)
https://github.com/vulhub/vulhub/tree/master/<product>/<CVE>
# Ready-to-deploy Docker lab for the vulnerability
Step 5 — Check Metasploit Module
msfconsole -q -x "search cve:<CVE-ID>; exit"
msfconsole -q -x "search type:exploit name:<product>; exit"
If a Metasploit module exists: prefer it over raw PoC — handles payload staging, bad chars, encoders.
Step 6 — Assess Exploitability
Before running:
# Check if target version is actually vulnerable
# Many PoCs have specific minor version requirements
# Linux: ASLR
cat /proc/sys/kernel/randomize_va_space # 2=full, 1=partial, 0=off
# Linux: mitigations
cat /proc/cpuinfo | grep -E 'flags|bugs' # spectre/meltdown status
# Windows: check patch level (if access)
systeminfo | findstr /B /C:"OS Version" /C:"Hotfix(s)"
# Network: verify service version matches
nmap -sV -p <port> <target>
