If you are using a Juniper Netscreen as a DHCP server you may find that when rebooting the device the DNS server entries for the DHCP change to the entries of the untrust port. This is down to the default DNS override settings and they can be changed either by using the GUI or Shell commands. I will show both ways below:
GUI:
- Log into the juniper and select Network > Interfaces > untrust port > Edit
- Deselect the setting Automatic Update DHCP Server Parameters
Shell:
Login to the shell (i.e. using Putty) then type the following command to disable the setting on the untrust port:
unset interface untrust dhcp client settings update-dhcpserver
Cisco Security Advisories
- Cisco Small Business 100, 300, and 500 Series Wireless Access Points Command Injection VulnerabilitiesMultiple vulnerabilities in the web-based management interface of certain Cisco Small Business 100, 300, and 500 Series Wireless Access Points could allow an authenticated, remote attacker to perform command injection attacks against an affected device. These vulnerabilities are due to improper validation of user-supplied input. An attacker could exploit these vulnerabilities by sending crafted HTTP requests […]
- Cisco Web Security Appliance Privilege Escalation VulnerabilityA vulnerability in the configuration management of Cisco AsyncOS for Cisco Web Security Appliance (WSA) could allow an authenticated, remote attacker to perform command injection and elevate privileges to root. This vulnerability is due to insufficient validation of user-supplied XML input for the web interface. An attacker could exploit this vulnerability by uploading crafted XML configuration files […]
- Cisco Unified Customer Voice Portal Cross-Site Scripting VulnerabilityA vulnerability in the web-based management interface of Cisco Unified Customer Voice Portal (CVP) could allow an unauthenticated, remote attacker to perform a cross-site scripting (XSS) attack against a user. This vulnerability is due to insufficient input validation of a parameter that is used by the web-based management interface. An attacker could exploit this vulnerability by […]
- Cisco Firepower Device Manager On-Box Software Remote Code Execution VulnerabilityA vulnerability in the REST API of Cisco Firepower Device Manager (FDM) On-Box Software could allow an authenticated, remote attacker to execute arbitrary code on the underlying operating system of an affected device. This vulnerability is due to insufficient sanitization of user input on specific REST API commands. An attacker could exploit this vulnerability by sending […]
