Etype Eserv

Stack-based buffer overflow in the FTP server in Etype Eserv 3.x, possibly 3.26, allows remote attackers to cause a denial of service (daemon crash) and possibly execute arbitrary code via a long argument to the ABOR command.

Buffer overflow in the logging feature of EServ 2.9.2 and earlier allows an attacker to execute arbitrary commands via a long MKD command.

EServ 2.92 Build 2982 allows remote attackers to cause a denial of service and possibly execute arbitrary commands via long HELO and MAIL FROM commands.

Etype Eserv 2.97 allows remote attackers to redirect traffic to other sites (aka FTP bounce) via the PORT command.

Directory traversal vulnerability in the IMAP service in EServ/3 3.25 allows remote authenticated users to read other user's email messages, create/rename arbitrary directories on the system, and delete empty directories via directory traversal sequences in the (1) CREATE, (2) SELECT, (3) DELETE, (4) RENAME, (5) COPY or (6) APPEND commands.

Directory traversal vulnerability in Etype Eserv 2.50 web server allows a remote attacker to read any file in the file system via a .. (dot dot) in a URL.

Etype Eserv 2.97 allows remote attackers to view password protected files via /./ in the URL.

Memory leak in eServ 2.9x allows remote attackers to cause a denial of service (memory exhaustion) via a large number of connections, whose memory is not freed when the connection is terminated.

The (1) FTP, (2) POP3, (3) SMTP, and (4) NNTP servers in EServer 2.92 through 2.97, and possibly 2.98, allow remote attackers to cause a denial of service (crash) via a large amount of data.

Etype Eserv 2.97 allows remote attackers to cause a denial of service (resource exhaustion) via a large number of PASV commands that consume ports 1024 through 5000, which prevents the server from accepting valid PASV.

The HTTP service in EServ/3 3.25 allows remote attackers to obtain sensitive information via crafted HTTP requests containing dot, space, and slash characters, which reveals the source code of script files.
