Security Advisory Bundled Publication for October 2020 – Cisco announced the release of patches for 17 high-severity flaws in its security appliances.

Cisco announced the release of security patches for 17 high-severity vulnerabilities in its security appliances as part of its Security Advisory Bundled Publication for October 2020.

The vulnerability impacts Adaptive Security Appliance (ASA), Firepower Threat Defense (FTD), and Firepower Management Center (FMC).

“The October 21, 2020 release of the ASA, FMC, and FTD Software Security Advisory Bundled Publication includes 17 Security Advisories that describe 17 vulnerabilities in ASA, FMC, and FTD Software. Cisco has released software updates for these vulnerabilities.” states the advisory.

“All of these vulnerabilities have a Security Impact Rating (SIR) of High.”

Most of the vulnerability addressed by the IT giant can be exploited by remote, unauthenticated attackers. The list of addressed vulnerabilities includes denial-of-service (DoS), CSRF, FMC authentication bypass, and MitM issues.

The company also fixed multiple vulnerabilities that require local access or authentication to be exploited, an attacker can trigger them to read or write files on a device, cause a DoS condition, bypass the secure boot mechanism, and escape containers and execute commands with root privileges.

The good news is that Cisco is not aware of attacks in the wild exploiting these vulnerabilities.

Cisco is also warning of attacks targeting the CVE-2020-3118 high severity vulnerability that affects multiple carrier-grade routers running the Cisco IOS XR Software.

The flaw resides in the Discovery Protocol implementation for Cisco IOS XR Software and could allow an unauthenticated, adjacent attacker to execute arbitrary code or cause a reload an affected device.
