Application: AntiVir PersonalEdition Classic Site: http://www.free-av.de/ Version: 7 and maybe lower OS: Windows XP, Windows 2000 Bugs: Local Privilige Escalation Product: ===== AntiVir PersonalEdition Classic Windows from Avira GmbH protects your computer from viruses, malware, unwanted programs and other dangers. About: ===== A few days ago I discovered a little 'Local Privilege Escalation' Bug in the current version of AntiVir PersonalEdition Classic. Description: ===== Part of AntiVir PersonalEdition Classic is a service called 'AntiVir PersonalEdition Classic Planer' which runs with SYSTEM rights. If you start the update process using the GUI, AntiVir will show you a status window. After finishing the process AntiVir offers you a report. Open the report using the button 'Report' and AntiVir will open the report in the well known application 'notepad.exe'. Well, since the update was initiated by the service 'AntiVir PersonalEdition Classic Planer', which runs with SYSTEM rights, notepad.exe inherits these rights now. Use 'notepad.exe' to *run* 'compmgmt.msc' for example and... Well, you know what might happen now.
