CVE-2002-1121

CVE-2002-1121 describes a vulnerability in several SMTP content filter engines, including GFI MailSecurity, InterScan VirusWall, and MIMEDefang, where they fail to detect fragmented emails as defined by RFC2046. This oversight allows remote attackers to bypass content filtering, including virus scanning, by sending messages in a fragmented "message/partial" format. The vulnerability has a CVSS score of 7.5, indicating high severity due to its network-based attack vector, low attack complexity, and potential for full confidentiality, integrity, and availability impact. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage surrounding this CVE.
