CVE-2005-2387
HighSummary
Multiple stack-based buffer overflows in GoodTech SMTP server 5.16 allow remote attackers to execute arbitrary code via a specially crafted RCPT TO command with a long DNS name or a large number of RCPT TO commands with a long email name argument in the last command.
Risk Assessment
An attacker can remotely take control of the SMTP server, leading to compromise of confidentiality, integrity, and availability of the system, and potential lateral movement within the internal network.
Recommendation
Immediately upgrade the GoodTech SMTP server to the latest available version that fixes this vulnerability. If upgrading is not possible, restrict access to the server to trusted hosts only or apply firewall rules to block suspicious SMTP commands.
