TITLE

Apple Mac OS X of ARDAgent Elevation of privilege vulnerability

DESCRIPTION

Open Scripting Architecture in Apple Mac OS X 10.4.11 and 10.5.4, and some other 10.4 and 10.5 versions, does not properly restrict the loading of scripting addition plugins, which allows local users to gain privileges via scripting addition commands to a privileged application, as originally demonstrated by an osascript tell command to ARDAgent. Successful exploits allow local attackers to execute arbitrary code with superuser privileges, completely compromising the affected computer. This issue is confirmed to affect Mac OS X 10.5 versions; earlier versions may also be vulnerable. A local attacker can invoke Mac OS X's ARDAgent via AppleScript (such as osascript). This vulnerability is currently being actively exploited by a Trojan named AppleScript.THT. Once the user is tricked into installing a malicious file with a Trojan horse, the Trojan horse will open file sharing, Web sharing, and remote login. The default file name of the Trojan is AStht_06.app, and the installation location is /Library/Caches. The problem is that "ARDAgent", which is owned by "root" and has the setuid bit set, can be invoked to execute shell commands via AppleScript (e.g. through "osascript"). This can be exploited to execute arbitrary commands with root privileges. SOLUTION: Grant only trusted users access to affected systems.
