Vulnerability Information

Severity: Medium
Vulnerability Published: 2006-05-25
Patch Published: N/A
CVE [?]: CVE-2006-2685
CPE [?]: cpe:/a:secureideas:basic_analysis_and_security_engine

Synopsis

The remote web server contains a PHP application that is prone to remote file inclusion attacks.

Description

The remote host is running BASE, a web-based tool for analyzing alerts from one or more SNORT sensors.

The version of BASE installed on the remote host fails to sanitize input to the 'BASE_path' parameter before using it in PHP include_once() function in several scripts. Provided PHP's 'register_globals' setting is enabled, an unauthenticated attacker may be able to exploit this flaw to view arbitrary files on the remote host or to execute arbitrary PHP code, possibly taken from third-party hosts.

Solution

Upgrade to BASE 1.2.5 or later.

Public Exploits

Target Network Port(s): 80
Target Asset(s): Services/www
Exploit Available: True (Metasploit Framework, Exploit-DB)
Exploit Ease: Exploits are available

Here's the list of publicly known exploits and PoCs for verifying the BASE Multiple Script BASE_path Parameter Remote File Inclusion vulnerability:

Metasploit: exploit/unix/webapp/base_qry_common
[BASE base_qry_common Remote File Include]
Exploit-DB: exploits/php/webapps/1823.txt
[EDB-1823: BASE 1.2.4 - melissa Snort Frontend Remote File Inclusion]
Exploit-DB: exploits/php/webapps/9908.rb
