Microsoft Windows Internet Printing Protocol service integer overflow

Vulnerability Note VU#793233

Original Release Date: 2008-10-15 | Last Revised: 2008-10-27

Overview

The Microsoft Windows Internet Printing Protocol (IPP) service contains an integer overflow vulnerability, which can allow a remote attacker to execute arbitrary code on a vulnerable system.

Description

IPP is an IP-based network protocol that allows remote printing and printer management. On Windows 2000 and XP, IIS comes with IPP enabled by default. IPP is optional on Windows 2003 systems. IPP by default is configured to only allow authenticated users; however, it may be configured to allow unauthenticated connections.

The Microsoft Windows IPP component, which is provided by msw3prt.dll, contains an integer overflow vulnerability that results in an overflow of heap memory. By creating a specific HTTP POST to the vulnerable server, the IPP server will attempt to make an SMB connection to a printer that is specified by the attacker. If this printer returns a malformed JOB_INFO_2 structure, the integer overflow vulnerability in IPP may be triggered, resulting in a four-byte memory overwrite and eventually code execution on the IPP server.

This vulnerability is being exploited in the wild.

Impact

By making a specially crafted request to an IPP server, a remote attacker may be able to execute arbitrary code on a vulnerable IPP server.
