|
||||||
|
This module exploits a flaw in the Web Start plugin component of Sun Java
|
||||||
|
Web Start. The arguments passed to Java Web Start are not properly validated.
|
||||||
|
By passing the lesser known -J option, an attacker can pass arbitrary options
|
||||||
|
directly to the Java runtime. By utilizing the -XXaltjvm option, as discussed
|
||||||
|
by Ruben Santamarta, an attacker can execute arbitrary code in the context of
|
||||||
|
an unsuspecting browser user.
|
||||||
|
|
||||||
|
This vulnerability was originally discovered independently by both Ruben
|
||||||
|
Santamarta and Tavis Ormandy. Tavis reported that all versions since version
|
||||||
|
6 Update 10 "are believed to be affected by this vulnerability."
|
||||||
|
|
||||||
|
In order for this module to work, it must be ran as root on a server that
|
||||||
|
does not serve SMB. Additionally, the target host must have the WebClient
|
||||||
|
service (WebDAV Mini-Redirector) enabled.
