Resumen

External SSL VPN / remote-access appliance attack matrix — Cisco ASA/AnyConnect, Fortinet FortiGate/FortiOS, Citrix NetScaler/ADC, Palo Alto GlobalProtect, Pulse Secure / Ivanti Connect Secure, SonicWall, F5 Big-IP. Covers version fingerprinting, CVE matrix (2018-2026), AAA backend identification, default credentials, configuration-disclosure paths, pre-auth RCE/SSRF/path-traversal exploits where applicable. Built from authorized-engagement Cisco ASA testing plus 2024-2026 enterprise VPN CVE landscape. Use whenever the target's perimeter exposes any SSL VPN appliance or remote-access gateway — these are the most common initial-access points in 2024-2026 actor TTPs.

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)

CVE-2024-40766	SonicOS specific	Access-control flaw	Specific firmware versions

SAML SP / IdP misconfigurations (always check)

Most enterprise VPNs now use SAML for SSO. Check SP metadata:

# Cisco ASA
curl -sk 'https://target/+CSCOE+/saml/sp/metadata' | head -50

# Fortinet
curl -sk 'https://target/remote/saml/metadata' | head -50

# Citrix
curl -sk 'https://target/saml/login' | head -30

Look for:

AuthnRequestsSigned="false" → see hunt-saml for XSW exploitation
WantAssertionsSigned="false" → severe; assertion-replay possible
Audience-restriction validation gaps
Public SP signing cert (for replay/forging attacks)

Default credentials (test sparingly — lockout risk)

Vendor	User	Password	Notes
Cisco ASA	admin	cisco	Default factory; rarely seen in prod
Cisco ASA	enable_15	cisco	Console
Fortinet	admin	(empty)	Factory default
Citrix NetScaler	nsroot	nsroot	Factory default
Citrix NetScaler	nsroot	(serial number)	Newer firmware
Palo Alto	admin	admin	Factory default
Pulse Secure	admin	password	Factory; CIS-hardened changes this
F5 Big-IP	root	default	Factory
F5 Big-IP	admin	admin	Common alternate
SonicWall	admin	password	Factory

⚠ Most enterprise targets have changed these. Test ≤2 attempts per account to avoid lockout.

Group / tunnel-group enumeration (Cisco-specific)

Cisco ASA AAA groups can sometimes be enumerated without auth.

# Tunnel group enumeration via timing
for group in DefaultRAGroup DefaultWEBVPNGroup SSLVPN Employees Contractors Vendors Partners Sales Marketing IT; do
  ms=$(curl -sk --max-time 10 -o /dev/null -w "%{time_total}" \
    -X POST "https://target/+webvpn+/index.html" \
    -d "username=test&password=test&group_list=$group&tgroup=&Login=Login")
  echo "$group: ${ms}s"
done
# Larger differential timing = group exists; valid groups respond slower in some builds

AAA backend identification

After auth fails, look at error response details:

Pattern in response	AAA backend
`a0=2` (Cisco)	Unknown user
`a0=3` (Cisco)	Wrong password
`a0=4` (Cisco)	Login restricted
`a0=12` (Cisco)	Account locked
`a0=115` (Cisco)	Generic auth fail (LDAP/RADIUS/AD layer error)
AADSTS in response body	Backed by Entra (SAML)
`Authentication failed via RADIUS`	RADIUS backend
`Invalid username or password` (generic)	LDAP or local DB

If you see SAML/Entra in the flow, pivot to m365-entra-attack skill for cred-spray strategy.

Trigger when recon surfaces:
- `*.<client>.example/+CSCOE+/logon.html` or similar `+CSCOE+` paths → Cisco ASA / AnyConnect
- `intranet.*` / `vpn.*` / `connect.*` / `webvpn.*` / `wc.*` / `remote.*` subdomains

## SAML SP / IdP misconfigurations (always check)

Most enterprise VPNs now use SAML for SSO. Check SP metadata:

```bash
# Cisco ASA
curl -sk 'https://target/+CSCOE+/saml/sp/metadata' | head -50

# Fortinet
curl -sk 'https://target/remote/saml/metadata' | head -50

# Citrix
curl -sk 'https://target/saml/login' | head -30
```

Look for:
- `AuthnRequestsSigned="false"` → see `hunt-saml` for XSW exploitation
- `WantAssertionsSigned="false"` → severe; assertion-replay possible
- Audience-restriction validation gaps
- Public SP signing cert (for replay/forging attacks)

---

## Default credentials (test sparingly — lockout risk)

| Vendor | User | Password | Notes |
|---|---|---|---|
| Cisco ASA | admin | cisco | Default factory; rarely seen in prod |
| Cisco ASA | enable_15 | cisco | Console |
| Fortinet | admin | (empty) | Factory default |
| Citrix NetScaler | nsroot | nsroot | Factory default |
| Citrix NetScaler | nsroot | (serial number) | Newer firmware |
| Palo Alto | admin | admin | Factory default |
| Pulse Secure | admin | password | Factory; CIS-hardened changes this |
| F5 Big-IP | root | default | Factory |
| F5 Big-IP | admin | admin | Common alternate |
| SonicWall | admin | password | Factory |

⚠ Most enterprise targets have changed these. Test ≤2 attempts per account to avoid lockout.

---

## Group / tunnel-group enumeration (Cisco-specific)

Cisco ASA AAA groups can sometimes be enumerated without auth.

```bash
# Tunnel group enumeration via timing
for group in DefaultRAGroup DefaultWEBVPNGroup SSLVPN Employees Contractors Vendors Partners Sales Marketing IT; do
  ms=$(curl -sk --max-time 10 -o /dev/null -w "%{time_total}" \
    -X POST "https://target/+webvpn+/index.html" \
    -d "username=test&password=test&group_list=$group&tgroup=&Login=Login")
  echo "$group: ${ms}s"
done
# Larger differential timing = group exists; valid groups respond slower in some builds
```

---

## AAA backend identification

After auth fails, look at error response details:

| Pattern in response | AAA backend |
|---|---|
| `a0=2` (Cisco) | Unknown user |
