A few higher-severity flaws exist in Cisco’s Webex video conferencing process, Cisco’s Movie Surveillance 8000 Sequence IP Cameras and Id Products and services Motor.
Cisco has issued patches for high-severity vulnerabilities plaguing its common Webex movie-conferencing procedure, its video surveillance IP cameras and its Id Solutions Motor network administration item.
All round, Cisco on Wednesday issued the three superior-severity flaws along with 11 medium-severity vulnerabilities.
The most extreme of these is a flaw (CVE-2020-3544) in Cisco’s Video Surveillance 8000 Series IP Cameras, which ranks 8.8 out of 10 on the CVSS scale.
“A vulnerability in the Cisco Discovery Protocol [CDP] implementation for Cisco Video Surveillance 8000 Sequence IP Cameras could allow for an unauthenticated, adjacent attacker to execute arbitrary code on an affected gadget or trigger the system to reload,” in accordance to Cisco’s security advisory.
The CDP is a network-discovery device that allows network directors detect neighboring Cisco units. The vulnerability is owing to missing checks when an IP digicam procedures a CDP packet.
To exploit the flaw, an attacker does not want to be authenticated. Having said that, the man or woman must be in the very same broadcast domain as the affected device — simply because CDP is a Layer 2 protocol, attackers ought to be Layer 2-adjacent.
“An attacker could exploit this vulnerability by sending a malicious [CDP] packet to an impacted machine,” in accordance to Cisco. “A successful exploit could let the attacker to execute code on the affected IP digital camera or result in it to reload unexpectedly, resulting in a denial of assistance (DoS) affliction.”
The vulnerability impacts cameras jogging a firmware release before than Launch 1..9-5 that have the CDP enabled, claimed Cisco. Of note, Cisco Video Surveillance 8000 Sequence IP Cameras are no longer getting offered as of July 24 nevertheless, vulnerability and security guidance does not finish until finally July 24, 2023.
Cisco also patched a significant-severity flaw impacting its Webex platform. This issue is critical specified the troves of workforces turning to online video conferencing devices through the pandemic – nevertheless, it is considerably sophisticated to exploit, as an attacker would want to be equally authenticated (needing legitimate qualifications on the Windows method) and area.
The vulnerability stems from the incorrect managing of listing paths at operate time. An attacker could exploit this vulnerability by placing a destructive DLL file in a specific spot on the qualified method, which would then execute when the susceptible software launches.
“A thriving exploit could enable the attacker to execute arbitrary code on the targeted method with the privileges of a further user’s account,” according to Cisco.
The flaw (CVE-2020-3535) has an effect on Cisco Webex Groups for Windows releases 3..13464. through 3..16040. it does not have an impact on Webex Teams for Android, Mac or iPhone and iPad.
Id Services Flaw
A remaining higher-severity flaw (CVE-2020-3467) exists in the web-dependent administration interface of Cisco Identity Providers Motor (ISE), a instrument that permits the creation and enforcement of security and obtain procedures for endpoint devices connected to the company’s routers and switches. The flaw enables authenticated (with valid Go through-Only Administrator credentials), remote attackers to modify parts of the configuration on an afflicted machine.
The bug stems from an incorrect enforcement of purpose-based accessibility management (RBAC) in the web-dependent management interface.
“An attacker could exploit this vulnerability by sending a crafted HTTP request to an impacted unit,” in accordance to Cisco. “A effective exploit could permit the attacker to modify elements of the configuration. The modified configuration could either allow unauthorized units on to the network or protect against licensed devices from accessing the network.”
Cisco explained it is not conscious of any public exploits for any of the a few bugs
