critical Nessus Plugin ID 27055

Language:

Synopsis

The remote FTP server is affected by several vulnerabilities.

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 1.3.0a. As such, it may be affected by one or more of the following vulnerabilities :

- An off-by-one string manipulation flaw exists in the 'sreplace' function. (CVE-2006-5815)

- A buffer overflow exists in the 'tls_x509_name_oneline' function of the mod_tls module involving the data length argument. (CVE-2006-6170)

- An off-by-two buffer overflow exists due to a failure to properly set the buffer size limit when 'CommandBufferSize' is specified in the configuration file, an issue which is disputed by the developers.
(CVE-2006-6171)

An attacker may be able to leverage this issue to crash the affected service or execute arbitrary code remotely, subject to the privileges under which the application operates.

Solution

Upgrade to ProFTPD version 1.3.0a or later.
