'Name' => 'Cisco RV110W/RV130(W)/RV215W Routers Management Interface Remote Command Execution',
'Description' => %q{
A vulnerability in the web-based management interface of the Cisco RV110W Wireless-N VPN Firewall,
Cisco RV130W Wireless-N Multifunction VPN Router, and Cisco RV215W Wireless-N VPN Router
could allow an unauthenticated, remote attacker to execute arbitrary code on an affected device.
The vulnerability is due to improper validation of user-supplied data in the web-based management interface.
An attacker could exploit this vulnerability by sending malicious HTTP requests to a targeted device.
A successful exploit could allow the attacker to execute arbitrary code on the underlying operating
system of the affected device as a high-privilege user.
RV110W Wireless-N VPN Firewall versions prior to 1.2.2.1 are affected.
RV130W Wireless-N Multifunction VPN Router versions prior to 1.0.3.45 are affected.
RV215W Wireless-N VPN Router versions prior to 1.3.1.1 are affected.
Note: successful exploitation may not result in a session, and as such,
on_new_session will never repair the HTTP server, leading to a denial-of-service condition.

DCNM exposes a file upload servlet (FileUploadServlet) at /fm/fileUpload.
An authenticated user can abuse this servlet to upload a WAR to the Apache Tomcat webapps
directory and achieve remote code execution as root.
This module exploits two other vulnerabilities, CVE-2019-1619 for authentication bypass on
versions 10.4(2) and below, and CVE-2019-1622 (information disclosure) to obtain the correct
directory for the WAR file upload.
This module was tested on the DCNM Linux virtual appliance 10.4(2), 11.0(1) and 11.1(1), and should
work on a few versions below 10.4(2). Only version 11.0(1) requires authentication to exploit
(see References to understand why).

This module attempts to gain root privileges by exploiting
a vulnerability in ktsuss versions 1.4 and prior.
The ktsuss executable is setuid root and does not drop
privileges prior to executing user specified commands,
resulting in command execution with root privileges.
This module has been tested successfully on:
ktsuss 1.3 on SparkyLinux 6 (2019.08) (LXQT) (x64); and
ktsuss 1.3 on SparkyLinux 5.8 (LXQT) (x64).

'Name' => "Cisco UCS Director default scpuser password",
'Description' => %q{
This module abuses a known default password on Cisco UCS Director. The 'scpuser'
has the password of 'scpuser', and allows an attacker to login to the virtual appliance
via SSH.
This module has been tested with Cisco UCS Director virtual machines 6.6.0 and 6.7.0.
Note that Cisco also mentions in their advisory that their IMC Supervisor and
UCS Director Express are also affected by these vulnerabilities, but this module
was not tested with those products.
