The FTP server in Serv-U 7.0.0.1 through 7.4.0.1 allows remote authenticated users to cause a denial of service (service hang) via a large number of SMNT commands without an argument.

Serv-U 7.0.0.1 through 7.3, including 7.2.0.1, allows remote authenticated users to cause a denial of service (CPU consumption) via a crafted stou command, probably related to MS-DOS device names, as demonstrated using "con:1".

Directory traversal vulnerability in the FTP server in Serv-U 7.0.0.1 through 7.3, including 7.2.0.1, allows remote authenticated users to overwrite or create arbitrary files via a ..\ (dot dot backslash) in the RNTO command.

Unspecified vulnerability in Serv-U File Server 7.0.0.1, and other versions before 7.2.0.1, allows remote authenticated users to cause a denial of service (daemon crash) via an SSH session with SFTP commands for directory creation and logging.

Serv-U FTP Server before 6.1.0.4 allows attackers to cause a denial of service (crash) via (1) malformed packets and possibly other unspecified issues with unknown impact and attack vectors including (2) use of "~" in a pathname, and (3) memory consumption of the daemon. NOTE: it is not clear whether items (2) and above are vulnerabilities.

Serv-U FTP Server 4.1 (possibly 4.0) allows remote attackers to cause a denial of service (application crash) via a SITE CHMOD command with a "\\...\" followed by a short string, causing partial memory corruption, a different vulnerability than CVE-2004-2111.

Serv-U FTP server before 5.1.0.0 has a default account and password for local administration, which allows local users to execute arbitrary commands by connecting to the server using the default administrator account, creating a new user, logging in as that new user, and then using the SITE EXEC command.

Stack-based buffer overflow in the site chmod command in Serv-U FTP Server before 4.2 allows remote attackers to execute arbitrary code via a long filename.

Buffer overflow in Serv-U ftp before 5.0.0.4 allows remote authenticated users to execute arbitrary code via a long time zone argument to the MDTM command.

Serv-U FTP server 4.x and 5.x allows remote attackers to cause a denial of service (application crash) via a STORE UNIQUE (STOU) command with an MS-DOS device name argument such as (1) COM1, (2) LPT1, (3) PRN, or (4) AUX.
