pyftpdlib FTP Server Multiple Vulnerabilities
Published: 2010-10-28 09:50:37
CVE Author: NIST National Vulnerability Database
CVSS Base Vector:
AV:N/AC:L/Au:N/C:P/I:P/A:P
Detection Type:
Remote Banner
Impact:
Successful exploitation will allow attacker to retrieve or upload arbitrary
system files or cause a denial of service.
Affected Versions:
ftpserver.py in pyftpdlib before 0.2.0
Technical Details:
Multiple flaws exist because pyftpdlib,
- allows remote authenticated users to access arbitrary files and directories
via a .. (dot dot) in a LIST, STOR, or RETR command.
- does not increment the attempted_logins count for a USER command that
specifies an invalid username, which makes it easier for remote attackers
to obtain access via a brute-force attack.
- allows remote attackers to cause a denial of service via a long command.
- does not limit the number of attempts to discover a unique filename, which
might allow remote authenticated users to cause a denial of service via
a STOU command.
- does not prevent TCP connections to privileged ports if the destination IP
address matches the source IP address of the connection from the FTP client,
which might allow remote authenticated users to conduct FTP bounce attacks
via crafted FTP data.
Solution Type:
Vendor Patch
Recommendations:
Upgrade to pyftpdlib version 0.5.2 or later.
Summary:
This host is running pyftpdlib FTP server and is prone to multiple
vulnerabilities.

What's vulnerability management?
Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
