(HP Issues Patch for Virtual Vault) Re: iPlanet Web Server Allows Remote Users to Execute Arbitrary Code on the Server and to Crash the Server
SecurityTracker Alert ID:  1001729
SecurityTracker URL:  http://securitytracker.com/id/1001729
CVE Reference:   GENERIC-MAP-NOMATCH   (Links to External Site)
Date:  Jun 12 2001
Impact:   Denial of service via network, Execution of arbitrary code via network, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): v4.1 SP 3-7
Description:   iPlanet announced that there is a vulnerability in the iPlanet Web Server that allows a remote user to crash the web services. The vulnerability also allows a remote user to gain shell access on the server (note that iPlanet did not mention this latter impact in their advisory).

It is reported that two vulnerabilities have been identified within iPlanet Web Server(iWS).

In the first vulnerability, a remote user can send manipulated HTTP request headers to iPlanet Web Server, Enterprise Edition version 4.1 Service Packs 3 through 7 (iWS4.1sp3-7), to cause a denial of service condition. This applies only to iWS4.1sp3-7 on the Microsoft Windows NT platform (but the vendor still recommends that all customers upgrade, regardless of the platform).

In the second vulnerability , a remote user can send manipulated HTTP request headers to an iPlanet Web Server or Netscape Enterprise Server (NES) that has the Web Publisher feature enabled to cause a denial of service condition. A remote user can also obtain shell access via this vulnerability.

Impact:   A remote user can cause the web server application to crash. In the Web Publisher vulnerability, a remote user can obtain shell access on the server.
Solution:   HP has released patch PHSS_24108 for the HP-UX 11.04 Virtual Vault (VVOS) release. (The iPlanet Web Server is included in Virtual Vault.)
Vendor URL:  www.iplanet.com/products/iplanet_web_enterprise/iwsalert5.11.html (Links to External Site)
Cause:   Boundary error, Input validation error
Underlying OS:  UNIX (HP/UX)
