Platform Notes

The raptor firewall was originally developed by Raptor Systems. Raptor Systems were acquired by Axent technologies in December 1997, and Axent Technologies were themselves acquired by Symantec in July 2000.

The VPN component is called PowerVPN.

Vendor IDs

Symantec Raptor sends the following Vendor ID in both main and aggressive mode:

  • 526170746f7220506f77657256706e20536572766572205b56382e315d ("Raptor PowerVpn Server [V8.1]")

The Vendor ID is the ASCII string Raptor PowerVpn Server [V8.1], which ike-scan displays as hex.

Authentication Methods

Symantec Raptor only appears to support Pre-Shared Key authentication for IKE Phase-1.

Here is an example of a Symentec Enterprise Firewall version 8.0 responding to a main mode request using pre-sherad key authentication:

$ ike-scan -M 172.16.3.65
Starting ike-scan 1.9.1 with 1 hosts (http://www.nta-monitor.com/tools/ike-scan/)
172.16.3.65     Main Mode Handshake returned

ISAKMP SA Lifetime

Lifetime in Seconds

Symantec Raptor supports any lifetime in seconds for IKE Phase-1, including no lifetime at all. If the lifetime in seconds is supplied as a variable-length attribute, it must be encoded in four bytes, otherwise Raptor will respond with BAD-PROPOSAL-SYNTAX.

$ ike-scan -M --lifetime=none --trans=5,2,1,2 172.16.3.65

Lifetime in Kilobytes

Symantec Raptor does not accept a lifetime in kilobytes for IKE Phase-1. If one is specified, it will respond with NO-PROPOSAL-CHOSEN. If both lifetime in kilobytes and lifetime in seconds is specified, then it will respond with BAD-PROPOSAL-SYNTAX.

Transform Ordering and Rewriting

Symantec Raptor always returns transform attributes in the order: Enc, Hash, Auth, Group [,Lifetime in Seconds] regardless of the order in which the attributes were sent by the initiator. Below are some examples illustrating this behaviour:

$ ike-scan -M --trans="(1=5,2=2,3=1,4=2)" 172.16.3.65
Starting ike-scan 1.9.1 with 1 hosts (http://www.nta-monitor.com/tools/ike-scan/)

Aggressive Mode

Symantec Raptor supports IKE Aggressive Mode for both site-to-site and remote access VPNs.

Here is an example of a site-to-site VPN responding to IKE aggressive mode. idtype 1 is ID_IPV4_ADDR, and the ID c0a87c07 is the hex representation of the IP address 192.168.124.7.

$ ike-scan -A --idtype=1 --id=0xc0a87c07 -M 172.16.3.65

        Nonce(64 bytes)
        ID(Type=ID_IPV4_ADDR, Value=172.16.3.65)
        Hash(20 bytes)

Here is an example of a remote access VPN. idtype 11 is ID_KEY_ID, and the ID is the username.

$ ike-scan -M -A --id=test --idtype=11 172.16.3.65
Starting ike-scan 1.9.1 with 1 hosts (http://www.nta-monitor.com/tools/ike-scan/)

        Nonce(64 bytes)
        ID(Type=ID_IPV4_ADDR, Value=172.16.3.65)
        Hash(20 bytes)

If we specify an unknown user, the VPN server responds with PAYLOAD-MALFORMED. This allows us to enumerate valid users.

$ ike-scan -M -A --id=nosuchuser --idtype=11 172.16.3.65
Starting ike-scan 1.9.1 with 1 hosts (http://www.nta-monitor.com/tools/ike-scan/)
