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.

Format string vulnerability in Ipswitch WS_FTP Professional 12 before 12.2 allows remote attackers to cause a denial of service (crash) via format string specifiers in the status code portion of an HTTP response.

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.

Ipswitch WS_FTP Server Manager before 6.1.1, and possibly other Ipswitch products, allows remote attackers to bypass authentication and read logs via a logLogout action to FTPLogServer/login.asp followed by a request to FTPLogServer/LogViewer.asp with the localhostnull account name.

Ipswitch WS_FTP Server Manager 6.1.0.0 and earlier, and possibly other Ipswitch products, might allow remote attackers to read the contents of custom ASP files in WSFTPSVR/ via a request with an appended dot character.

Buffer overflow in Ipswitch WS_FTP Home client allows remote FTP servers to have an unknown impact via a long "message response."

Format string vulnerability in Ipswitch WS_FTP Home 2007.0.0.2 and WS_FTP Professional 2007.1.0.0 allows remote FTP servers to cause a denial of service (application crash) or possibly execute arbitrary code via format string specifiers in a connection greeting (response).

Ipswitch Instant Messaging (IM) 2.0.8.1 and earlier allows remote attackers to cause a denial of service (NULL dereference and application crash) via a version field containing zero.

Directory traversal vulnerability in the IM Server (aka IMserve or IMserver) in Ipswitch Instant Messaging (IM) 2.0.8.1 and earlier allows remote authenticated users to create arbitrary empty files via a .. (dot dot) in the recipient field.

Format string vulnerability in the logging function in the IM Server (aka IMserve or IMserver) in Ipswitch Instant Messaging (IM) 2.0.8.1 and earlier allows remote authenticated users to cause a denial of service (daemon crash) and possibly have unspecified other impact via format string specifiers in an IP address field.
