Trustwave's SpiderLabs Security Advisory TWSL2010-007: Passlogix v-GO Self-Service Password Reset Bypass via Invalid SSL Certificate https://www.trustwave.com/spiderlabs/advisories/TWSL2010-007.txt Published: 2010-12-10 Version: 1.0 Vendor: Oracle Passlogix (http://www.passlogix.com/) Product: Passlogix v-GO Self-Service Password Reset and OEM versions Version(s) affected: Versions prior to 7.0A - note that no currently supported release is affected Internet Explorer Versions Vulnerable: IE6, IE7 Product description: Passlogix v-GO SSPR provides users with a fast, secure way to regain access to their computer by automating Windows password reset. Users can reset their password or unlock their Windows account directly from their locked out workstation, so that they can get to their applications within seconds - without having to pick up the telephone or go to another workstation. Credit: Garrett Held of Trustwave's SpiderLabs CVE: CVE-2010-4506 Finding: When a user clicks the button on the login window to reset their Windows or AD password, a locked-down IE browser shows a form to answer questions before allowing a reset. If for any reason an invalid SSL Certificate is used by the password reset site, the resulting Internet Explorer alert will ask if the user would like to accept, deny, or view the details. By navigating through the windows using the following method, a user can execute a program without authentication. When the certificate error popup is shown there will be three tabs: "General", "Details", and "Certification Path" Choose the "Details" tab then click on the "Copy to File" button that is now shown in the bottom right. This will cause a "Certificate Export" wizard to appear. Click the "Next >" button until you reach the "File To Export" page (third page) which displays a "Browse" button. Click this and a "Save As" dialog box will appear which also allows you to navigate the filesystem. You can now browse the file system for executables such as "explorer.exe" and launch an application by right clicking the file and selecting "Open". While an SSL certificate left to expire may create this problem, other methods may be used to induce certificate failures, such as: * Man-In-The-Middle attack, which requires network access to spoof the router and relay any certificate back to client except a valid one. * System settings change, such as a future date, which would not match the certificate.
