Cisco Jabber | Breaking Cybersecurity News | The Hacker News

Cisco has once again fixed four  previously disclosed critical bugs  in its Jabber video conferencing and messaging app that were inadequately addressed, leaving its users susceptible to remote attacks. The vulnerabilities, if successfully exploited, could allow an authenticated, remote attacker to execute arbitrary code on target systems by sending specially-crafted chat messages in group conversations or specific individuals. They were reported to the networking equipment maker on September 25 by Watchcom , three weeks after the Norwegian cybersecurity firm publicly disclosed multiple security shortcomings in Jabber that were found during a penetration test for a client in June. The new flaws, which were uncovered after one of its clients requested a verification audit of the patch, affects all currently supported versions of the Cisco Jabber client (12.1 - 12.9). "Three of the four vulnerabilities Watchcom  disclosed in September  have not been sufficiently...

Networking equipment maker Cisco has released a new version of its Jabber video conferencing and messaging app for Windows that includes patches for multiple vulnerabilities—which, if exploited, could allow an authenticated, remote attacker to execute arbitrary code. The flaws, which were uncovered by Norwegian cybersecurity firm Watchcom during a pentest, affect all currently supported versions of the Jabber client (12.1-12.9) and has since been fixed by the company. Two of the four flaws can be exploited to gain remote code execution (RCE) on target systems by sending specially crafted chat messages in group conversations or specific individuals. The most severe of the lot is a flaw (CVE-2020-3495, CVSS score 9.9) that's caused by improper validation of message contents, which could be leveraged by an attacker by sending maliciously-crafted Extensible Messaging and Presence Protocol ( XMPP ) messages to the affected software. "A successful exploit could allow the...

Vulnerability Management (VM) has long been a cornerstone of organizational cybersecurity. Nearly as old as the discipline of cybersecurity itself, it aims to help organizations identify and address potential security issues before they become serious problems. Yet, in recent years, the limitations of this approach have become increasingly evident.  At its core, Vulnerability Management processes remain essential for identifying and addressing weaknesses. But as time marches on and attack avenues evolve, this approach is beginning to show its age. In a recent report, How to Grow Vulnerability Management into Exposure Management (Gartner, How to Grow Vulnerability Management Into Exposure Management, 8 November 2024, Mitchell Schneider Et Al.), we believe Gartner® addresses this point precisely and demonstrates how organizations can – and must – shift from a vulnerability-centric strategy to a broader Exposure Management (EM) framework. We feel it's more than a worthwhile read an...
