Rule:

--
Sid:
100000590
--
Summary:
This event is generated when an attempt is made to exploit a remote file 
include vulnerability in the "Indexu" application running on a webserver. 
Access to the file "editor_add.php" using a remote file being passed as the 
"admin_template_path" parameter may indicate that an exploitation attempt has 
been attempted. 

--
Impact:
Information gathering and system integrity compromise. Possible unauthorized 
administrative access to the server or application. Possible execution of 
arbitrary code of the attackers choosing in some cases.

--
Detailed Information:
This event indicates that an attempt has been made to include a file from a 
remote machine via the "admin_template_path" parameter in the "editor_add.php" 
script used by the "Indexu" application running on a webserver.

If stringent input checks are not performed by the CGI application, it may also 
be possible for an attacker to execute system binaries or malicious code of the 
attackers choosing.

This event is generated when an attempt is made to gain unauthorized access to 
a CGI application running ona web server. Some applications do not perform 
stringent checks when validating the credentials of a client host connecting to 
the services offered on a host server. This can lead to unauthorized access and 
possibly escalated privileges to that of the administrator. Data stored on the 
machine can be compromised and trust relationships between the victim server 
and other hosts can be exploited by the attacker.

--
Affected Systems:
All systems running CGI applications using Indexu
--
Attack Scenarios:
An attacker can access an authentication mechanism and supply his/her own 
credentials to gain access. Alternatively the attacker can exploit weaknesses 
to gain access as the administrator by supplying input of their choosing to the 
underlying CGI script.

--
Ease of Attack:
Simple. Exploits exist.

--
False Positives:
None known.

--
False Negatives:
None known.

--
Corrective Action:
Ensure the system is using an up to date version of the software and has had 
all vendor supplied patches applied.
