ProFTPD < 1.3.3d 'mod_sql' Buffer Overflow

Medium Nessus Plugin ID 51366

Synopsis

The remote FTP server is affected by a heap-based buffer overflow 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 1.3.3d. Such versions are reportedly affected by a heap-based buffer overflow vulnerability in the function 'sql_prepare_where()' in the file 'contrib/mod_sql.c'. An unauthenticated, remote attacker may be able to exploit this in combination with an earlier SQL injection vulnerability (CVE-2009-0542) to execute arbitrary code with root privileges.

Note that Nessus did not actually test for the flaw but instead has relied on the version in ProFTPD's banner.

Solution

Upgrade to ProFTPD version 1.3.3d or later.
