Washington University : Security Vulnerabilities, CVEs, CVSS score >= 6

Buffer overflow in the skey_challenge function in ftpd.c for wu-ftp daemon (wu-ftpd) 2.6.2 allows remote attackers to cause a denial of service and possibly execute arbitrary code via a s/key (SKEY) request with a long name.

wu-ftpd 2.6.2 and earlier, with the restricted-gid option enabled, allows local users to bypass access restrictions by changing the permissions to prevent access to their home directory, which causes wu-ftpd to use the root directory instead.

ftpd.c in wu-ftpd 2.6.2, when running on "operating systems that only allow one non-connected socket bound to the same local address," does not close failed connections, which allows remote attackers to cause a denial of service.

Buffer overflow in the SockPrintf function in wu-ftpd 2.6.2 and earlier, when compiled with MAIL_ADMIN option enabled on a system that supports very long pathnames, might allow remote anonymous users to execute arbitrary code by uploading a file with a long pathname, which triggers the overflow when wu-ftpd constructs a notification message to the administrator.

Vulnerability in wu-ftpd 2.6.0, and possibly earlier versions, which is unrelated to the ftpglob bug described in CVE-2001-0550.

wu-ftpd 2.6.1 allows remote attackers to execute arbitrary commands via a "~{" argument to commands such as CWD, which is not properly handled by the glob function (ftpglob).

Format string vulnerability in wu-ftp 2.6.1 and earlier, when running with debug mode enabled, allows remote attackers to execute arbitrary commands via a malformed argument that is recorded in a PASV port assignment.

Race condition in wu-ftpd and BSDI ftpd allows remote attackers to gain root access via the SITE EXEC command.

Buffer overflow in WU-FTPD and related FTP servers allows remote attackers to gain root privileges via MAPPING_CHDIR.

Buffer overflows in wuarchive ftpd (wu-ftpd) and ProFTPD lead to remote root access, a.k.a. palmetto.

Certain configurations of wu-ftp FTP server 2.4 use a _PATH_EXECPATH setting to a directory with dangerous commands, such as /bin, which allows remote authenticated users to gain root access via the "site exec" command.

FTP servers can allow an attacker to connect to arbitrary ports on machines other than the FTP client, aka FTP bounce.
