Date: Wed Jun 22 20:46:08 2005 From: labs-no-reply at idefense.com (iDEFENSE Labs) Subject: iDEFENSE Security Advisory 06.22.05: IpSwitch WhatsUp Professional 2005 (SP1) SQL Injection Vulnerability IpSwitch WhatsUp Professional 2005 (SP1) SQL Injection Vulnerability iDEFENSE Security Advisory 06.22.05 www.idefense.com/application/poi/display?id=268&type=vulnerabilities June 22, 2005 I. BACKGROUND WhatsUp Professional 2005 SP1 is a network management solution for small and mid sized organizations. Further information is available at: http://www.ipswitch.com/Products/WhatsUp/professional/index.html II. DESCRIPTION Remote exploitation of a SQL injection vulnerability in IpSwitch Inc.'s WhatsUp Professional 2005 Service Pack 1 could allow a remote attacker to gain administrative access to the application. The main logon screen for the web based front end does not properly validate input, allowing for SQL injection attacks to occur. SQL commands can be submitted through the "User Name" and "Password" fields on the default login page. The web front end is not enabled by default and must be running for the application to be vulnerable. It can be enabled under the "Configure", "Program Options" menu by checking the "Enable web server on port [80]" checkbox. Exploit code for this vulnerability is unnecessary; the following SQL injection attacks can be executed in the "User Name" field of the http://[target]/NmConsole/Login.asp page: Reset the Admin user password with a blank password: - 'UPDATE WebUser SET sPassword=DEFAULT WHERE sUserName='Admin'-- Elevate Guest user privileges to Admin privileges: - 'UPDATE WebUser SET nUserRightsMask=-1 WHERE sUserName='guest'-- III. ANALYSIS Successful exploitation allows unauthenticated remote attackers to gain administrative access to the WhatsUp Professional application. SQL injection attacks can be used to either elevate the privileges of the Guest user or to change/erase the password of the Admin user. Either approach will provide a remote attacker with full administrative access to the application. By default, the Guest user is enabled but has limited access to the application and the account has a blank password. IV. DETECTION iDEFENSE has confirmed the existence of this vulnerability against WhatsUp Gold Professional 2005 SP1 running on Windows XP Professional SP1. V. WORKAROUND Disabling the web front end to WhatsUp Gold Professional 2005 (SP1) will prevent the ability to exploit this vulnerability. It can be disabled under the "Configure", "Program Options" menu by unchecking the "Enable web server on port [80]" checkbox. VI. VENDOR RESPONSE This vulnerability is addressed in WhatsUP Pro 2005 SP1a. A change log detailing changes in SP1a is available at: http://www.ipswitch.com/forums/shwmessage.aspx?ForumID=20&MessageID=7699 VII. CVE INFORMATION The Common Vulnerabilities and Exposures (CVE) project has assigned the name CAN-2005-1250 to this issue. This is a candidate for inclusion in the CVE list (http://cve.mitre.org), which standardizes names for security problems. VIII.
