APP: MDConfig Malformed Version Command
This signature detects attempts to exploit a known vulnerability against MDConfig for Mdaemon. MDConfig v3.5.0 and earlier versions are vulnerable. Attackers can send a blank VERS request to obtain sensitive information; attackers can then use a separate connection to send the correct VERS request and consume mdconfig resources, causing a denial of service and preventing administrator logins.
Extended Description
Remote attackers could exploit this vulnerability to obtain the MDaemon version number and cause an MDConfig denial of service.
