How to check the Firmware version running on Cisco IP Phones

-


Firmware Naming Convention

These conventions are used in naming the IP Phone firmware:
SCCP firmware: P003xxyyzzww.bin: where x represents the major version, y represents the major subversion, z represents the maintenance version, and w represents the maintenance subversion.
SIP firmware: P0S3-xx-y-zz: where x represents the major version, y represents the minor version, and z represents the subversions.
MGCP firmware: P0M3-xx-y-zz: where M is the third character. The major, minor, and subversions for MGCP are consistent with the SIP naming convention
For Java-based IP phones, the following naming conventions are used for image files.
SCCP firmware: TERMnn.xx-y-z-ww or SCCPnn.xx-y-zz-ww: where n represents the phone type, x represents the major version, y represents the major subversion, z represents the maintenance version, and w represents the maintenance subversion.

Firmware Offered by CUCM

Complete these steps in order to view the software versions that the Cisco Unified Communications Manager offers:
  1. Log in to the Cisco Unified Communications Manager Administration page.
  2. Navigate to Device > Device Settings > Device Defaults.

    The Device Defaults Configuration list appears. This list shows the firmware that the IP Phone will load when it registers with CUCM. In this example, the Cisco 7961 IP Phone will load SCCP41.8-4-1S when it register with the Cisco Unified Communications Manager.

Methods

Complete one of these methods in order to find the firmware version of an IP phone:
  • You can access the firmware version directly from the phone from the Settings Menu.
    1. Press Settings, scroll down, and select Status.
    2. Scroll down, and select Firmware Versions.
      This lists the versions of the different kinds of load.
  • If the IP Phone is located in a remote location, telnet to the Cisco switch to which the IP Phone is connected and issue the show cdp neighbors <module/port> detail command.

  • If you know the IP address of the IP Phone, you can access directly the HTTP interface of the IP Phone.
    Open a web browser, and enter http://<ip phone ip address>/. Where ip phone ip address is the IP address of the IP Phone.

DNS Tunneling Attack - You might know this !

-
Image
  Introduction: In the world of cybersecurity, attackers continuously explore new techniques to bypass network defenses and exfiltrate sensitive information. One such technique gaining prominence is DNS tunneling. DNS tunneling allows attackers to use the DNS protocol as a covert communication channel, exploiting its ubiquitous nature and inherent characteristics. This blog post delves into the concept of DNS tunneling, its working mechanism, potential risks, and methods to mitigate this emerging threat. Understanding DNS Tunneling: DNS (Domain Name System) is the backbone of the internet, responsible for translating domain names into IP addresses. Its primary purpose is to facilitate communication between devices. However, this fundamental protocol can be manipulated to serve as a covert channel for data transmission. DNS tunneling involves encapsulating data within DNS queries and responses, effectively bypassing network security measures that may not scrutinize DNS traffic as c...
