Cisco on Wednesday rolled out  security updates  to address a critical flaw impacting its IP Phone 6800, 7800, 7900, and 8800 Series products. The vulnerability, tracked as CVE-2023-20078, is rated 9.8 out of 10 on the CVSS scoring system and is described as a command injection bug in the web-based management interface arising due to insufficient validation of user-supplied input. Successful exploitation of the bug could allow an unauthenticated, remote attacker to inject arbitrary commands that are executed with the highest privileges on the underlying operating system. "An attacker could exploit this vulnerability by sending a crafted request to the web-based management interface," Cisco  said  in an alert published on March 1, 2023. Also patched by the company is a high-severity denial-of-service (DoS) vulnerability affecting the same set of devices, as well as the Cisco Unified IP Conference Phone 8831 and Unified IP Phone 7900 Series.

Cisco has released a new security advisory warning of a high-severity flaw affecting IP Phone 7800 and 8800 Series firmware that could be potentially exploited by an unauthenticated attacker to cause remote code execution or a denial-of-service (DoS) condition. The networking equipment major said it's working on a patch to address the vulnerability, which is tracked as  CVE-2022-20968  (CVSS score: 8.1) and stems from a case of insufficient input validation of received Cisco Discovery Protocol (CDP) packets. CDP is a  proprietary   network-independent protocol  that is used for collecting information related to nearby, directly connected devices such as hardware, software, and device name, among others. It's enabled by default. "An attacker could exploit this vulnerability by sending crafted Cisco Discovery Protocol traffic to an affected device," the company  said  in an alert published on December 8, 2022. "A successful exploit could allow the attacker to

As a vCISO, you are responsible for your client's cybersecurity strategy and risk governance. This incorporates multiple disciplines, from research to execution to reporting. Recently, we published a comprehensive playbook for vCISOs, "Your First 100 Days as a vCISO – 5 Steps to Success" , which covers all the phases entailed in launching a successful vCISO engagement, along with recommended actions to take, and step-by-step examples.  Following the success of the playbook and the requests that have come in from the MSP/MSSP community, we decided to drill down into specific parts of vCISO reporting and provide more color and examples. In this article, we focus on how to create compelling narratives within a report, which has a significant impact on the overall MSP/MSSP value proposition.  This article brings the highlights of a recent guided workshop we held, covering what makes a successful report and how it can be used to enhance engagement with your cyber security clients.

A critical vulnerability in the firmware of Cisco small business phones lets an unauthenticated attacker to remotely eavesdrop on private conversation and make phone calls from vulnerable devices without needing to authenticate, Cisco warned. LISTEN AND MAKE PHONE CALLS REMOTELY The vulnerability ( CVE-2015-0670 ) actually resides in the default configuration of certain Cisco IP phones is due to " improper authentication ", which allows hackers to remotely eavesdrop on the affected devices by sending specially crafted XML request. Moreover, the vulnerability could be exploited by hackers to make phone calls remotely from the vulnerable phones as well as to carry out other attacks by making use of the information gathered through the audio interception activity. AFFECTED DEVICES The devices affects the Cisco's small business SPA300 and SPA500 Internet Protocol (IP) phones running firmware version 7.5.5, however, Cisco alerts that later versions of these
