Synopsis

The remote FTP server is affected by multiple vulnerabilities.

 

Vulnerability Description

The remote host is using ProFTPD, a free FTP server for Unix and Linux.

According to its banner, the version of ProFTPD installed on the remote host is earlier than 1.3.3c. Such versions are reportedly affected by the following vulnerabilities:

When ProFTPD is compiled with 'mod_site_misc' and a directory is writable, a user can use 'mod_site_misc' to create or delete a directory outside the writable directory, create a symlink located outside the writable directory, or change the time of a file located outside the writable directory. (Bug #3519)

A stack-based buffer overflow exists in the server's 'pr_netio_telnet_gets()' function, which can be triggered by when reading user input containing a TELNET_IAC escape sequence. (Bug #3521)

Note that we did not actually test for the flaws but instead has relied on the version in ProFTPD's banner so this may be a false positive.

 

Solution

Upgrade to ProFTPD version 1.3.3c or later.
