The STARTTLS implementation in the server in Ipswitch IMail 11.03 and earlier does not properly restrict I/O buffering, which allows man-in-the-middle attackers to insert commands into encrypted SMTP sessions by sending a cleartext command that is processed after TLS is in place, related to a "plaintext command injection" attack, a similar issue to CVE-2011-0411.

Multiple buffer overflows in Ipswitch IMail before 2006.21 allow remote attackers or authenticated users to execute arbitrary code via (1) the authentication feature in IMailsec.dll, which triggers heap corruption in the IMail Server, or (2) a long SUBSCRIBE IMAP command, which triggers a stack-based buffer overflow in the IMAP Daemon.

Stack-based buffer overflow in the IMAP server for Ipswitch IMail 8.12 and 8.13, and other versions before IMail Server 8.2 Hotfix 2, allows remote authenticated users to cause a denial of service (crash) via a SELECT command with a large argument.

Buffer overflow in the login functions in IMAP server (imapd) in Ipswitch IMail 5.0 and earlier allows remote attackers to cause a denial of service and possibly execute arbitrary code via (1) a long user name or (2) a long password.

Multiple features in Ipswitch IMail Server before 8.13 allow remote attackers to cause a denial of service (crash) via (1) a long sender field to the Queue Manager or (2) a long To field to the Web Messaging component.

Unknown vulnerability in the Web calendaring component of Ipswitch IMail Server before 8.13 allows remote attackers to cause a denial of service (crash) via "specific content."

Buffer overflow in the LDAP component of Ipswitch IMail 7.1 and earlier allows remote attackers to execute arbitrary code via a long "bind DN" parameter.

Buffer overflow in IPSwitch IMail SMTP server 6.06 and possibly prior versions allows remote attackers to execute arbitrary code via a long From: header.

The web server in IPSWITCH IMail 6.04 and earlier allows remote attackers to read and delete arbitrary files via a .. (dot dot) attack.

Ipswitch IMAIL server 6.02 and earlier allows remote attackers to cause a denial of service via the AUTH CRAM-MD5 command.

Ipswitch IMail 5.0 and 6.0 uses weak encryption to store passwords in registry keys, which allows local attackers to read passwords for e-mail accounts.

Buffer overflow in Ipswitch IMail Service 5.0 allows an attacker to cause a denial of service (crash) and possibly execute arbitrary commands via a long URL.

Buffer overflow in IMonitor in IMail 5.0 allows remote attackers to cause a denial of service, and possibly execute arbitrary commands, via a long string to port 8181.

IPswitch WS_FTP allows local users to gain additional privileges and modify or add mail accounts by setting the "flags" registry key to 1920.

IPswitch IMail allows local users to gain additional privileges and modify or add mail accounts by setting the "flags" registry key to 1920.
