Symantec Enterprise Firewall/VPN Appliances 100, 200, and 200R running firmware before 1.63 and Gateway Security 320, 360, and 360R running firmware before 622 allow remote attackers to bypass filtering and determine whether the device is running services such as tftpd, snmpd, or isakmp via a UDP port scan with a source port of UDP 53.

The bug was discovered 09/22/2004. The weakness was released 09/22/2004 by Mike Sues as confirmed advisory (CERT.org). The advisory is shared at kb.cert.org. This vulnerability is uniquely identified as CVE-2004-1473 since 02/13/2005. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details are unknown but an exploit is available. MITRE ATT&CK project uses the attack technique T1592 for this issue.

After immediately, there has been an exploit disclosed. It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 11580 (Firewall UDP Packet Source Port 53 Ruleset Bypass), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Firewalls and running in the context r.

Upgrading to version 1.63 eliminates this vulnerability.It is possible to mitigate the weakness by firewalling . The best possible mitigation is suggested to be applying a restrictive firewalling. A possible mitigation has been published immediately after the disclosure of the vulnerability. Furthermore it is possible to detect and prevent this kind of attack with TippingPoint and the filter 3115.

The vulnerability is also documented in the databases at X-Force (17470), Tenable (11580), SecurityFocus (BID 11237†), OSVDB (10205†) and Secunia (SA12635†). Entries connected to this vulnerability are available at VDB-44, VDB-849, VDB-848 and VDB-847. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
