5 High Impact Flaws Affect Cisco Routers, Switches, IP Phones and Cameras

5 High Impact Flaws Affect Cisco Routers, Switches, IP Phones and Cameras

Feb 05, 2020
Several Cisco-manufactured network equipments have been found vulnerable to five new security vulnerabilities that could allow hackers to take complete control over them, and subsequently, over the enterprise networks they power. Four of the five high-severity bugs are remote code execution issues affecting Cisco routers, switches, and IP cameras, whereas the fifth vulnerability is a denial-of-service issue affecting Cisco IP phones. Collectively dubbed ' CDPwn ,' the reported vulnerabilities reside in the various implementations of the Cisco Discovery Protocol (CDP) that comes enabled by default on virtually all Cisco devices and can not be turned OFF. Cisco Discovery Protocol (CDP) is an administrative protocol that works at Layer 2 of the Internet Protocol (IP) stack. The protocol has been designed to let devices discover information about other locally attached Cisco equipment in the same network. According to a report Armis research team shared with The Hacker N
Flaw Affecting Millions of Cisco Devices Let Attackers Implant Persistent Backdoor

Flaw Affecting Millions of Cisco Devices Let Attackers Implant Persistent Backdoor

May 14, 2019
Researchers have discovered a severe vulnerability in Cisco products that could allow attackers to implant persistent backdoor on wide range devices used in enterprises and government networks, including routers, switches, and firewalls. Dubbed Thrangrycat or 😾😾😾, the vulnerability, discovered by researchers from the security firm Red Balloon and identified as CVE-2019-1649, affects multiple Cisco products that support Trust Anchor module (TAm). Trust Anchor module (TAm) is a hardware-based Secure Boot functionality implemented in almost all of Cisco enterprise devices since 2013 that ensures the firmware running on hardware platforms is authentic and unmodified. However, researchers found a series of hardware design flaws that could allow an authenticated attacker to make the persistent modification to the Trust Anchor module via FPGA bitstream modification and load the malicious bootloader. "An attacker with root privileges on the device can modify the contents of
SaaS Compliance through the NIST Cybersecurity Framework

SaaS Compliance through the NIST Cybersecurity Framework

Feb 20, 2024Cybersecurity Framework / SaaS Security
The US National Institute of Standards and Technology (NIST) cybersecurity framework is one of the world's most important guidelines for securing networks. It can be applied to any number of applications, including SaaS.  One of the challenges facing those tasked with securing SaaS applications is the different settings found in each application. It makes it difficult to develop a configuration policy that will apply to an HR app that manages employees, a marketing app that manages content, and an R&D app that manages software versions, all while aligning with NIST compliance standards.  However, there are several settings that can be applied to nearly every app in the SaaS stack. In this article, we'll explore some universal configurations, explain why they are important, and guide you in setting them in a way that improves your SaaS apps' security posture.  Start with Admins Role-based access control (RBAC) is a key to NIST adherence and should be applied to every SaaS a
Cisco finds new Zero-Day Exploit linked to NSA Hackers

Cisco finds new Zero-Day Exploit linked to NSA Hackers

Sep 20, 2016
Network equipment vendor Cisco is finally warning its customers of another zero-day vulnerability the company discovered in the trove of NSA's hacking exploits and implants leaked by the group calling itself " The Shadow Brokers ." Last month, the Shadow Brokers published firewall exploits, implants, and hacking tools allegedly stolen from the NSA's Equation Group, which was designed to target major vendors including, Cisco, Juniper, and Fortinet. A hacking exploit, dubbed ExtraBacon , leveraged a zero-day vulnerability (CVE-2016-6366) resided in the Simple Network Management Protocol (SNMP) code of Cisco ASA software that could allow remote attackers to cause a reload of the affected system or execute malicious code. Now Cisco has found another zero-day exploit , dubbed "Benigncertain," which targets PIX firewalls. Cisco analyzed the exploit and noted that it had not identified any new flaws related to this exploit in its current products. But,
