iPlanet Web Server Enterprise Edition and Netscape Enterprise Server malformed Web Publisher command causes denial-of-service
A vulnerability exists in iPlanet Web Server, Enterprise Edition and Netscape Enterprise Server in which a malformed Web Publisher command can crash the web server process. This vulnerability only affects Windows NT based servers.
ProCheckup has reported a vulnerability in iPlanet Web Server, Enterprise Edition and Netscape Enterprise Server running on Windows NT based operating systems. The iPlanet and NES servers provide a feature called Web Publisher. According to NES documentation:
Netscape Enterprise Server 4.0 clients can use Web Publisher to collaborate on projects by directly accessing, editing, and managing file on remote servers. Web Publisher provides sophisticated features for server clients, such as file management, editing and publishing, and access control.
An unauthenticated remote attacker can cause a denial-of-service condition by sending malformed ?wp-html-rend commands to a vulnerable server.
Disable Web Publishing
Another method for disabling Web Publisher is to use a Netscape Server Application Programming Interface (NSAPI) Server Application Function (SAF):
Filter HTTP Traffic
It may be possible to use an application layer filter to detect and block HTTP requests containing the ?wp-html-rend command.
