VID 18102
Severity 40
Port 110
Protocol TCP
Class POP3
Detailed Description A version of Alt-N MDaemon POP3 Server which is older than version 9.0.6 is detected as running on the host. Alt-N MDaemon is an SMTP/POP/IMAP server for Microsoft Windows operating systems. MDaemon versions prior to 9.0.6 are vulnerable to a heap-based buffer overflow vulnerability in 'USER' and 'APOP' command processing part of the MDaemon POP3 server. The vulnerability could be triggered with providing a long string to USER or APOP commands with '@' characters included in the string. A remote, authenticated attacker could exploit this vulnerability to cause the application to crash or execute arbitrary code on the system with the privileges of the POP3 service.

* Note: This check solely relied on the banner of the remote POP3 server to assess this vulnerability, so this might be a false positive.
