Critical Vulnerabilities Under Cisco Security updates 

 1. Denial of Service Vulnerability (CVE-2018-0368

A critical vulnerability existing in the reassembly logic for fragmented IPv4 packets of Cisco StarOS running on virtual platforms allow a remote attacker can perform reload the process leads to perform denial of service (DoS) attack.

Improper handling of fragmented IPv4 packets Allows an attacker could exploit this vulnerability by sending a malicious IPv4 packet across an affected device.

2. Web UI Command Injection Vulnerability(CVE-2018-0341)

A command injection vulnerability affected the web-based UI of Cisco IP Phone 6800, 7800, and 8800 Series with Multiplatform Firmware which allow an attacker perform a command injection and execute commands with the privileges of the web server.

Medium Severity Vulnerabilities

1.Credential Logging Information Disclosure Vulnerability (CVE-2018-0368 )

A vulnerability in Cisco Digital Network Architecture (DNA) Center could allow an authenticated, local attacker to access sensitive information on an affected system.

2. Denial of Service Vulnerability (CVE-2018-0385)

A vulnerability in the detection engine parsing of Security Socket Layer (SSL) protocol packets for Cisco Firepower System Software could allow an attacker to perform a denial of service (DoS) condition due to the Snort process unexpectedly restarting.

3. Access Control Policy Bypass Vulnerability (CVE-2018-0384)

A vulnerability in the detection engine of Cisco FireSIGHT System Software could allow an unauthenticated, remote attacker to bypass a URL-based access control policy that is configured to block traffic for an affected system.

4. Policy Bypass Vulnerability (CVE-2018-0383)

A vulnerability in the detection engine of Cisco FireSIGHT System Software could allow an unauthenticated, remote attacker to bypass a file policy that is configured to block the transfer of files to an affected system via FTP.

5. Denial of Service Vulnerability (CVE-2018-0370)

A vulnerability in the detection engine of Cisco Firepower System Software could allow an unauthenticated, remote attacker to cause one of the detection engine processes to run out of memory and thus slow down traffic processing.
6. Cross-Site Scripting Vulnerability (CVE-2018-0366)

A vulnerability in the web-based management interface of Cisco Web Security Appliance (WSA) could allow an unauthenticated, remote attacker to conduct a reflected cross-site scripting (XSS) attack against a user of the web-based management interface of an affected device.
