CVE-2002-0309 describes an information disclosure vulnerability in the SMTP proxy of Symantec Enterprise Firewall (SEF) 6.5.x. When NAT translation occurs to an address other than the firewall, the firewall's physical interface name and address are inadvertently included in SMTP protocol exchanges. This allows remote attackers to gather sensitive firewall configuration details. The vulnerability has a CVSS score of 5.0, indicating a medium severity. It is easily exploitable over the network with low attack complexity and requires no authentication, potentially leading to a partial compromise of confidentiality. There is no evidence of active exploitation, nor is public exploit code available in Metasploit, Nuclei, or ExploitDB. The vulnerability has received no community discussion or media coverage, suggesting a low level of public awareness or concern.
