Rule:

--
Sid:
100000687

--
Summary:
This event is generated when an empty CTCP NOTICE message is sent to an IRC 
channel.

--
Impact:
If the EnergyMech IRC Bot receives such a message, a denial of service 
condition will occur.

--
Detailed Information:
Whenever the EnergyMech IRC Bot processes a null CTCP NOTICE message, a denial 
of service condition occurs. Note that this rule is set to examine only default 
IRC ports, in order to conserve system resources; if you are particularly 
concerned about this exploit, you may wish to set the ports to "any", as IRC 
channels can exist on any port.

--
Affected Systems:
EnergyMech <= 3.0.1

--
Attack Scenarios:
An attacker could exploit this vulnerability via any IRC client, or by using an 
automated script.

--
Ease of Attack:
Simple.

--
False Positives:
None known.

--
False Negatives:
None known.

--
Corrective Action:
Upgrade to version 3.0.2 or greater.
