|
||||
This module exploits a command injection vulnerability
|
||||
discovered in HP SiteScope 11.30 and earlier versions (tested in 11.26
|
||||
and 11.30). The vulnerability exists in the DNS Tool allowing an
|
||||
attacker to execute arbitrary commands in the context of the service. By
|
||||
default, HP SiteScope installs and runs as SYSTEM in Windows and does
|
||||
not require authentication. This vulnerability only exists on the
|
||||
Windows version. The Linux version is unaffected.
