Rule:
--
Sid:
1050
--
Summary:
This event is generated when a request is made to a webserver using the 
the command 'GETPROPERTIES'. This may be an indication that a buffer 
overflow attack may be in process.
--
Impact:
If successful, this attack will allow attackers to run code of their 
choosing on the victim server.
--
Detailed Information:
The web publishing feature in iPlanet Web Server 4.1 is vulnerable to a 
buffer overflow.
--
Affected Systems:
iPlanet Web Server 4.1 up to Service Pack 8
--
Attack Scenarios:
An attacker can spawn a remote shell on the server and execute any 
command they desire.
--
Ease of Attack:
Difficult.  Exploit code does not appear to exist as of June 2003, so an
attacker would need to write the code themselves.
--
False Positives:
Legimate uses of web publishing.
--
False Negatives:
This vulnerability can be exploited using any number of web publishing 
commands, however this rule only generates an event on one specific 
command (GETPROPERTIES).
--
Corrective Action:
Disable web publishing or upgrade your web server software.
