# ClaudeWave Editor Note: enterprise-vpn-attack This Claude Code skill identifies and exploits vulnerabilities in enterprise SSL VPN and remote-access appliances including Cisco ASA, Fortinet FortiGate, Citrix NetScaler, Palo Alto GlobalProtect, Pulse Secure, SonicWall, and F5 Big-IP. It maps version fingerprinting techniques, CVE patterns from 2018-2026, authentication backend identification, default credential testing, and pre-authentication exploits like RCE and path traversal. Use this when reconnaissance reveals SSL VPN login pages or web-management interfaces exposed on the target perimeter, as these represent primary initial-access vectors in current enterprise attack patterns.

## When to use this skill

Trigger when recon surfaces:
- `*.<client>.example/+CSCOE+/logon.html` or similar `+CSCOE+` paths → Cisco ASA / AnyConnect
- `intranet.*` / `vpn.*` / `connect.*` / `webvpn.*` / `wc.*` / `remote.*` subdomains
- Port 443 returning login pages with `Server: Apache` or banner like "AnyConnect", "FortiGate", "NetScaler", "GlobalProtect", "Pulse", "Ivanti"
- TCP 8443 / 4443 / 10443 / 8888 (common VPN web-mgmt ports)
- HTTP responses with `Set-Cookie: webvpn=` (Cisco) / `SVPNCOOKIE=` (Fortinet) / `NSC_AAA=` (Citrix) / `DSAuthSession=` (Pulse) / `BIGipServer*` (F5)

DO NOT use for:
- Internal lateral-movement post-foothold (out of scope per user's boundary)
- VPN client-side bugs (different attack class)
- IPsec / L2TP / OpenVPN (different protocols, not SSL VPN web stack)

## Vendor identification (fingerprinting)

### Cisco ASA / AnyConnect
```bash
curl -skI 'https://target/+CSCOE+/logon.html' | head -10
# Look for: Set-Cookie: webvpn=; X-Frame-Options: SAMEORIGIN; CSP: ... block-all-mixed-content
# Login page contains: "AnyConnect", "CSCOE", "logon.html"
```
ASA version: not banner-disclosed in modern builds; need to derive from JS file paths or test specific paths.

```bash
# Path-based version hints (older builds leaked builds in URLs)
curl -sk 'https://target/+CSCOE+/sdesktop/scan-finalize?path=test'
curl -sk 'https://target/+CSCOE+/saml/sp/metadata'         # 200 = SAML auth enabled
curl -sk 'https://target/CSCOSSLC/config-auth'             # AnyConnect handshake endpoint
```

### Fortinet FortiGate / FortiOS
```bash
curl -skI 'https://target/remote/login' | head -10
# Look for: Set-Cookie: SVPNCOOKIE=, Server header missing or "xxxxxxxx-xxxxx"
# Login page contains: "FortiGate", "Fortinet", "SSL-VPN"
```
Version: `/remote/info` sometimes leaks (older), or `/login?username=` 302 response

### Citrix NetScaler / ADC / Gateway
```bash
curl -skI 'https://target/' | head -10
# Look for: Set-Cookie: NSC_AAA=, Set-Cookie: NSC_USER=, Server: NetScaler
# Login page contains: "NetScaler", "Citrix Gateway"

# Version banner
curl -sk 'https://target/vpn/index.html' | grep -oE 'NetScaler/[0-9.]+|NS[0-9.]+'
curl -sk 'https://target/menu/neo'                # 200 if vulnerable to CVE-2019-19781 era
```

### Palo Alto GlobalProtect
```bash
curl -skI 'https://target/global-protect/login.esp' | head -10
# Look for: Set-Cookie: PHPSESSID= (yes, GP uses PHP), Server: Apache (PA-VM internal)
# Page contains: "GlobalProtect Portal", "PAN-OS"

# Version banner via login page
curl -sk 'https://target/global-protect/login.esp' | grep -oE 'GlobalProtect Portal[\s\S]{0,200}'
# Or check meta tag
curl -sk 'https://target/global-protect/login.esp' | grep -oE 'panui-[0-9.]+'
```

### Pulse Secure / Ivanti Connect Secure
```bash
curl -skI 'https://target/dana-na/auth/url_default/welcome.cgi' | head -10
# Look for: Set-Cookie: DSAuthSession=, DSPREAUTH=
# Page contains: "Pulse Secure" or "Ivanti Connect Secure"

# Version
curl -sk 'https://target/dana-na/auth/url_default/welcome.cgi' | grep -oE 'Pulse Connect Secure[^<]*|ivanti[^<]*[0-9.]+'
```

### SonicWall NetExtender / SMA
```bash
curl -skI 'https://target/cgi-bin/welcome' | head -10
# Look for: Set-Cookie: swap=, swapauth=
# Page contains: "SonicWall", "NetExtender", "SMA"
```

### F5 Big-IP / APM
```bash
curl -skI 'https://target/my.policy' | head -10
# Look for: Set-Cookie: BIGipServer*, MRHSession=
# Server: BIG-IP (sometimes)
```

apk-redteam-pipelineSkill

End-to-end Android APK red-team pipeline — automated APK acquisition (Play Store + apkpure + apkmirror fallback), jadx decompilation, secret/URL/JWT/Firebase grep, pinned-cert extraction, exported-component enumeration, Frida runtime instrumentation templates, intent-injection probes. Built from an authorized external red-team engagement where 7 APKs were pulled manually, 4 download attempts truncated, and a hardcoded JWT + 30 internal API endpoints were recovered from one of the apps. Use when target has a mobile app catalogue (Play Store developer page), when you find an APK URL hosted on a web server, or when post-recon mentions "mobile app" in scope.

autopilotSlash Command

Run autonomous hunt loop on a target — scope check → recon → rank surface → hunt → validate → report with configurable checkpoints. Usage: /autopilot target.com [--paranoid|--normal|--yolo]

bb-local-toolkitSkill

Local-tooling companion to the bug-bounty orchestrator — carries the SAME complete bug-bounty workflow, but reach for THIS variant when you also need to resolve where tools, wordlists, and clones are installed on the local machine (jhaddix, SecLists, trufflehog, ffuf, dalfox, ghauri); for pure orchestration/routing use the bug-bounty skill. Workflow it covers — recon (subdomain enumeration, asset discovery, fingerprinting, HackerOne scope, source code audit), pre-hunt learning (disclosed reports, tech stack research, mind maps, threat modeling), vulnerability hunting (IDOR, SSRF, XSS, auth bypass, CSRF, race conditions, SQLi, XXE, file upload, business logic, GraphQL, HTTP smuggling, cache poisoning, OAuth, timing side-channels, OIDC, SSTI, subdomain takeover, cloud misconfig, ATO chains, agentic AI), LLM/AI security testing (chatbot IDOR, prompt injection, indirect injection, ASCII smuggling, exfil channels, RCE via code tools, system prompt extraction, ASI01-ASI10), A-to-B bug chaining (IDOR→auth bypass, SSRF→cloud metadata, XSS→ATO, open redirect→OAuth theft, S3→bundle→secret→OAuth), bypass tables (SSRF IP bypass, open redirect bypass, file upload bypass), language-specific grep (JS prototype pollution, Python pickle, PHP type juggling, Go template.HTML, Ruby YAML.load, Rust unwrap), and reporting (7-Question Gate, 4 validation gates, human-tone writing, templates by vuln class, CVSS 3.1, PoC generation, always-rejected list, conditional chain table, submission checklist). Use when you need the local install path of a tool / wordlist / clone for a hunt, or as the full-workflow variant when operating from this local toolkit; for general routing use the bug-bounty skill. 中文触发词:漏洞赏金、安全测试、渗透测试、漏洞挖掘、信息收集、子域名枚举、XSS测试、SQL注入、SSRF、安全审计、漏洞报告

bb-methodologySkill

Use at the START of any bug bounty hunting session, when switching targets, or when feeling lost about what to do next. Master orchestrator that combines the 5-phase non-linear hunting workflow with the critical thinking framework (developer psychology, anomaly detection, What-If experiments). Routes to all other skills based on current hunting phase. Also use when asking "what should I do next" or "where am I in the process.

bug-bountySkill

Complete bug bounty workflow — recon (subdomain enumeration, asset discovery, fingerprinting, HackerOne scope, source code audit), pre-hunt learning (disclosed reports, tech stack research, mind maps, threat modeling), vulnerability hunting (IDOR, SSRF, XSS, auth bypass, CSRF, race conditions, SQLi, XXE, file upload, business logic, GraphQL, HTTP smuggling, cache poisoning, OAuth, timing side-channels, OIDC, SSTI, subdomain takeover, cloud misconfig, ATO chains, agentic AI), LLM/AI security testing (chatbot IDOR, prompt injection, indirect injection, ASCII smuggling, exfil channels, RCE via code tools, system prompt extraction, ASI01-ASI10), A-to-B bug chaining (IDOR→auth bypass, SSRF→cloud metadata, XSS→ATO, open redirect→OAuth theft, S3→bundle→secret→OAuth), bypass tables (SSRF IP bypass, open redirect bypass, file upload bypass), language-specific grep (JS prototype pollution, Python pickle, PHP type juggling, Go template.HTML, Ruby YAML.load, Rust unwrap), and reporting (7-Question Gate, 4 validation gates, human-tone writing, templates by vuln class, CVSS 3.1, PoC generation, always-rejected list, conditional chain table, submission checklist). Use for ANY bug bounty task — starting a new target, doing recon, hunting specific vulns, auditing source code, testing AI features, validating findings, or writing reports. 中文触发词:漏洞赏金、安全测试、渗透测试、漏洞挖掘、信息收集、子域名枚举、XSS测试、SQL注入、SSRF、安全审计、漏洞报告

bugcrowd-reportingSkill

Bugcrowd-specific reporting tactics complementing report-writing: VRT category search-and-fallback strategy when no exact match exists, manual severity override when VRT defaults underrate impact, severity-request paragraph as first body section, OOS-clause rebuttal templates (rate limiting on auth-flow endpoints, debug-info framing, user-enumeration with sensitive PII, theoretical-issue counter), chained-finding cross-reference patterns, target selection for QA-vs-prod programs, researcher-side hygiene (Bugcrowdninja email alias, account state restoration, friendly-tester posture). Use when filing a Bugcrowd submission, when VRT default seems wrong, when triager closes as OOS or downgrades severity, when chaining linked submissions, or when scope distinguishes production from QA. Pairs with report-writing and triage-validation.

chainSlash Command

Build an exploit chain — given bug A, finds B and C to combine for higher severity and payout. Knows common chain patterns: IDOR→ATO, SSRF→cloud metadata, XSS→ATO, open redirect→OAuth theft, S3→bundle→secret→OAuth. Usage: /chain

cloud-iam-deepSkill

Cloud IAM red-team attack chain across AWS, Azure, GCP — focused on EXTERNAL exploitation paths and post-credential-discovery privilege analysis. Covers IAM enumeration (aws iam, az role, gcloud iam), STS/AssumeRole chaining, Azure Managed Identity abuse (via SSRF/leak), GCP service account JSON abuse, IMDSv1/v2 attacks via SSRF, K8s ServiceAccount token privilege analysis once held (token discovery / cluster exposure is owned by hunt-k8s), role-trust-policy confused-deputy, cross-account assume-role enumeration, IAM privilege escalation patterns (24+ AWS, 8+ Azure, 6+ GCP), and AWS Cognito Identity Pool unauthenticated-role attack chain (GetId → GetCredentialsForIdentity → IAM role abuse). Built for the case where recon yields a credential (key, JSON, token) and you need to know what it grants and how to escalate. Use when an AWS key / Azure secret / GCP service account JSON / K8s SA token surfaces from a code repo, JS bundle, APK, breach corpus, or SSRF chain.
