SMTP proxy in Symantec Enterprise Firewall (SEF) 6.5.x includes the firewall's physical interface name and address in an SMTP protocol exchange when NAT translation is made to an address other than the firewall, which could allow remote attackers to determine certain firewall configuration information.

Security readout for executives and security teams

This vulnerability can leak internal firewall details during SMTP handling. In a specific NAT scenario, Symantec Enterprise Firewall 6.5.x may disclose the firewall interface name and address, giving outsiders configuration clues. The sources do not show code execution, bypass, or confirmed active exploitation. Likely limited to organizations still running Symantec Enterprise Firewall 6.5.x with its SMTP proxy enabled and NAT configured as described. Because this is a 2002-era product, exposure should be confirmed through asset inventory rather than assumed. Treat this as low urgency unless the legacy firewall is still internet-facing. The business concern is reconnaissance value, not direct breach evidence. Prioritize discovery and replacement of obsolete perimeter infrastructure. Mitigation focus: Check Symantec’s referenced advisory for official remediation guidance.; Identify and retire any remaining Symantec Enterprise Firewall 6.5.x deployments.; Review whether SMTP proxying is required on affected legacy firewalls..
