Vulnerability Note VU#513068

eIQnetworks Enterprise Security Analyzer Syslog server buffer overflow

Original Release date: 18 Jan 2007 | Last revised: 18 Jan 2007

Overview

The eIQnetworks Enterprise Security Analyzer Syslog server contains a buffer overflow vulnerability, which may allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.

Description

Enterprise Security Analyzer

eIQnetworks Enterprise Security Analyzer (ESA) "... provides essential real-time security intelligence to help decipher hacker/virus behavior, combat security threats and meet regulatory compliance requirements across the entire IT infrastructure – network devices and hosts." ESA is also provided on an OEM basis as Astaro Report Manager, Fortinet FortiReporter, iPolicy Security Reporter, SanMina Viking Multi-Log Manager, Secure Computing G2 Security Reporter, and Top Layer Network Security Analyzer.

ESA Syslog server

The ESA Syslog server is provided by the SyslogServer.exe executable. This server collects data from managed machines and listens on 10617/tcp.

The problem

The ESA Syslog server contains a buffer overflow vulnerability.

Impact

A remote, unauthenticated attacker may be able to execute arbitrary code on a system running the vulnerable Syslog component.

Solution

Apply an update
This vulnerability is addressed in eIQnetworks ESA 2.5.0.

OEM versions of ESA, including Astaro Report Manager, Fortinet FortiReporter, iPolicy Security Reporter, SanMina Viking Multi-Log Manager, Secure Computing G2 Security Reporter, and Top Layer Network Security Analyzer should be updated to version 4.5.4 or later.


Restrict access

You may wish to block access to the vulnerable software from outside your network perimeter, specifically by blocking access to the ports used by eIQnetworks ESA Syslog server (typically 10617/tcp). This will limit your exposure to attacks. However, blocking at the network perimeter would still allow attackers within the perimeter of your network to exploit the vulnerability. The use of host-based firewalls in addition to network-based firewalls can help restrict access to specific hosts within the network. It is important to understand your network's configuration and service requirements before deciding what changes are appropriate.
