HP-UX Line Printer Daemon Vulnerable to Directory Traversal

Vulnerability Note VU#638011

Original Release Date: 2001-11-21 | Last Revised: 2001-12-06

Overview

A remotely exploitable directory traversal vulnerability exists in the HP-UX line printer daemon.

Description

The line printer daemon (rlpdaemon) enables various clients to share printers over a network. By sending a specially crafted print request to an HP-UX host running the rlpdaemon, a local or remote attacker can create arbitrary files or directories on the target host. Intruders may find this vulnerability attractive to exploit because the line printer daemon is enabled by default to provide printing services.

Impact

An attacker may be able to execute arbitrary code on the target system with the privileges of the line printer daemon, typically superuser.

Solution

Contact HP for patches.

Workaround

Disable the line printer daemon until a patch can be applied.
