Networking supplier Cisco has disclosed and released key security patches for critical flaws affecting Webex Teams for Windows and a video surveillance camera series.
Cisco said that a vulnerability in the loading mechanism in the Cisco Webex Teams client for Windows could allow an authenticated, local attacker to load a malicious library. To exploit this vulnerability, the attacker needs valid credentials on the Windows system.
The vulnerability is due to incorrect handling of directory paths at run time. Attackers could exploit this vulnerability by placing a malicious DLL file in a specific location on the targeted system. This file will execute when the vulnerable application launches.
A successful exploit could allow the attacker to execute arbitrary code on the targeted system with the privileges of another user’s account.
The company said that another vulnerability in the Cisco Discovery Protocol implementation for Cisco Video Surveillance 8000 Series IP Cameras could allow an unauthenticated, adjacent attacker to execute arbitrary code on an affected device or cause the device to reload.
This vulnerability is due to missing checks when an IP camera processes a Cisco Discovery Protocol packet.
An attacker could exploit this vulnerability by sending a malicious Cisco Discovery Protocol packet to an affected device.
A successful exploit could allow the attacker to execute code on the affected IP camera or cause it to reload unexpectedly, resulting in a denial of service (DoS) condition.
The third flaw affects the web management interface of Cisco Identity Services Engine (ISE).
A vulnerability in the web-based management interface of Cisco Identity Services Engine (ISE) could allow an authenticated, remote attacker to modify parts of the configuration on an affected device.
A successful exploit could allow the attacker to modify parts of the configuration. The modified configuration could either allow unauthorised devices onto the network or prevent authorized devices from accessing the network.
Cisco has released software updates for all the vulnerabilities and there are no workarounds that address these vulnerabilities.
Cisco Webex ealier said it supported half a billion meeting participants who generated 25 billion meeting minutes in the month of April.
The Cisco Webex platform has seen unprecedented demand and more than triples its normal volume in the social distancing times.
Cisco also unveiled key Webex enhancements to help, including: security and compliance capabilities, intelligent and actionable insights to deliver consistent user experiences, and an integration with Box.
Cisco has integrated Webex Teams and Box, the leading cloud content management platform that is used by 68 percent of the Fortune 500 and nearly 100,000 businesses globally,” Cisco has said.
