Severity: Critical
Vulnerability Published: 2010-05-06
Patch Published: 2010-05-05
CVE [?]: CVE-2010-1549
CPE [?]: cpe:/a:hp:loadrunner

Synopsis

It is possible to execute arbitrary commands on the remote system.

Description

The version of the LoadRunner Agent installed on the remote host allows an unauthorized attacker to execute arbitrary commands on the remote system provided 'Secure Channel' is disabled (which is disabled by default).

Run the scan.

Here are a few examples of how to run the plugin in the command line. Note that the examples below demonstrate the usage on the Linux / Unix platform.

Basic usage:

/opt/nessus/bin/nasl loadrunner_agent_remote_command_execution.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a loadrunner_agent_remote_command_execution.nasl -t <IP/HOST>

Run the plugin with trace script execution written to the console (useful for debugging):

/opt/nessus/bin/nasl -T - loadrunner_agent_remote_command_execution.nasl -t <IP/HOST>

Run the plugin with using a state file for the target and updating it (useful for running multiple plugins on the target):

/opt/nessus/bin/nasl -K /tmp/state loadrunner_agent_remote_command_execution.nasl -t <IP/HOST>

Go back to menu.
